Risk for Severe Weather for Parts of NW Alabama

1 hour 8 min ago

The SPC maintains a risk for severe weather across much of the Lower Mississippi Valley today. The risk area does come as far east as Alabama and includes much of the northwestern portion of the state, which has been outlined in green. The risk is valid until 7 AM Friday morning.

We are seeing some convection ongoing to our west, with a few severe storms. Heading through the rest of today, we are expecting additional showers and storms to develop and some will become severe. This activity is then expected to head east through the evening hours and should impact portions of Northwest Alabama after midnight tonight.

Areas around Red Bay, Florence, Haleyville, Decatur, and Huntsville could see some strong and locally severe storms overnight as this activity heads into the state. Hail and gusty winds will be the main threats.  However, as these storms enter the state, they will be weakening and should not cause too many problems. This activity is expected to begin rapidly dissipating during the early morning hours as it pushes into and across Central Alabama. We are not expecting any severe weather for Birmingham, Tuscaloosa, Anniston, or Gadsden. The left-over convection should only be some scattered showers that will affect the area during the pre-dawn and early morning hours.

Once these showers push through in the morning, we are expecting improving conditions with mostly sunny skies and highs near 80 for you Friday.

Update on Birmingham Weather Radio

2 hours 18 min ago

The National Weather Service has been working diligently to repair serious equipment with the Birmingham NOAA Weather Radio broadcasting from Red Mountain overlooking downtown Birmingham. Through some extraordinary measures, they have been able to get the broadcast back on the air on a limited basis. I’ve posted their statement below for all the information.

Showers Late Tonight/Early Tomorrow

7 hours 51 min ago

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

BIG WARM-UP: We are starting off this day with some upper 30s over Northeast Alabama… Fort Payne reports 37, Black Creek is at 38 just before daybreak. But, despite the morning chill, we warm quickly today, and most communities will see a high in the low 80s this afternoon. The GFS is printing a high of 84 for Birmingham, and if we see that today will be the warmest day so far in 2014. The sky will be partly to mostly sunny.

TO THE WEST: SPC has the standard “slight risk” of severe weather up later today and tonight for areas northwest of Alabama, and that risk clips the northwest corner of our state.

A band of showers and thunderstorms will enter Northwest Alabama between 10:00 p.m. and midnight tonight, and initially the storms could be strong up around Muscle Shoals, Florence, Russellville, and Hamilton. Gusty winds and some small hail are possible, but the storms will weaken very quickly as they move deeper into Alabama, and by the time it reaches Birmingham, Tuscaloosa, Anniston, and Gadsden, we expect nothing more than scattered, light rain showers between 3:00 and 6:00 a.m.

TOMORROW: After those pre-dawn showers end, the day tomorrow looks very nice with ample sunshine and a high in the mid to upper 70s.

THE ALABAMA WEEKEND: It will be the warmest weekend so far this year with highs up in the mid 80s Saturday and Sunday. We expect a good supply of sunshine both days, and the chance of a shower is so small that we won’t mention it.

EYES TO THE WEST: While we enjoy a warm, calm weekend, a significant severe weather outbreak will unfold over the Southern Plains Saturday and Sunday as a vigorous, negative tilt upper trough moves out of the Rockies, encountering very unstable air. Severe thunderstorms with large hail, damaging wind, and a few tornadoes are possible Sunday west of our state.

SPC continues a risk of severe weather over a good part of Alabama Monday.

THE ALABAMA SEVERE WEATHER THREAT: No doubt we will have the dual threat of heavy rain/flooding, and severe thunderstorms Monday, Monday night, and into Tuesday morning, but the exact details of how it all unfolds are still not clear at this early stage of the game.

The GFS hints some type of MCS (mesoscale convective system) could move into Alabama Monday morning with potential for heavy rain, but the core threat for severe weather still seems to be Monday afternoon and Monday night.

It remains to be seen how morning storms might impact the Monday evening threat, but the GFS shows a good bit of surface based instability Monday evening (CAPE values over 2,000 j/kg over West Alabama). Thankfully the low level bulk shear values have come down, but there is still sufficient shear for some tornado threat. The low level jet is in the 40-45 knot range, not overwhelming, but enough for strong to severe storms.

FLOODING THREAT: Rain amounts of over 3 inches are possible over North Alabama (generally along and north of I-20) Monday through Tuesday, and that could be enough for some flooding issues. If you live in a flood prone area, be aware of the possibility. This could actually turn out to be the biggest threat of the event.

IMPORTANT NOTE: You will probably hear all kind of hyperbole on the Internet and across social media about the event early next week. Nobody at this point really knows how the mesoscale features will play out that determine the true magnitude and scope of the threat. And, there is no need for comparisons to April 27, 2011. That was a generational event, and you probably won’t see another one like that for many, many years. But, remember, if there is only one tornado in the entire state, and if it happens to come through your neighborhood, then that becomes YOUR April 27. When people ask me “will this be like April 27?”… I don’t answer because of that.

COLDER AIR: After the rain and storms, the weather will turn colder by Wednesday and Thursday. The 00Z GFS has backed off on the strength of the upper trough over the eastern half of the U.S., but one way or another temperatures will be below average over the latter half of the week. I fully expect some of the colder North Alabama valleys and protected areas to reach the upper 30s by Thursday or Friday morning.

Take some time to watch the Weather Xtreme video for the maps, graphics, and details.

BIRMINGHAM WEATHER RADIO OUTAGE: It is important to note the Birmingham NOAA Weather Radio transmitter is down. Received this note from John DeBlock at the NWS last night…

“Based on some late afternoon updates, we are now hopeful that the Birmingham transmitter may be back on the air before the threat of severe weather next week.

As you can imagine, pulling together any sort of repair on short notice is challenging in the best of circumstances. We are working closely with technicians and our regional and national management teams to do everything we can to return the transmitter to operations as soon as possible.”

We recommend the MyWarn and iMap WeatherRadio smart phone apps with ABC 33/40 as your chosen partner so you can watch our streaming coverage.

AT THE BEACH: Mostly sunny days and fair nights on the coast through the weekend (from Panama City to Gulf Shores). Highs in the low 70s on the immediate coast, with mid 80s just a few miles inland. Showers and storms return to the Gulf Coast Monday and Tuesday of next week.

Warm Days Ahead

Wed, 04/23/2014 - 14:14

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

SEVERE CLEAR: Hard to find a decent cloud in the Alabama sky this afternoon; temperatures are generally in the mid to upper 70s, the humidity is low, and the visibility is excellent. Tonight will be clear and cool… we drop into the upper 40s by daybreak.

WARMER TOMORROW: Tomorrow will be another dry day; the sky partly to mostly sunny with a high up in the low 80s, making it one of the warmest days so far in 2014. To the west, SPC has the standard “slight risk” of severe weather up from roughly Memphis down to Shreveport, but those storms will fizzle fast as they near Alabama late tomorrow night.

FRIDAY: A band of showers and storms will enter the northwest corner of Alabama around midnight tomorrow night, but they will weaken quickly as the upper air support lifts out… by the time they reach Birmingham, Tuscaloosa, Anniston, and Gadsden during the pre-dawn hours (2:00 to 6:00 a.m.) there won’t be much left, and rain amounts will be light and spotty.

The day Friday looks nice with a partly sunny sky and a high around 80 degrees. I don’t expect any rain in the state after the early morning showers end.

THE ALABAMA WEEKEND: No doubt it will be the warmest weekend so far this year, with mid 80s Saturday and Sunday. The sky will be partly sunny both days, and the chance of rain looks very small. Not zero, but the chance of any one spot seeing an afternoon shower is only about one in ten, and barely worth mentioning in the forecast.

TO THE WEST: A very significant severe weather threat is shaping up for parts of the southern U.S. over the weekend…

ALABAMA’S SEVERE WEATHER THREAT: Again I stress there is no way of knowing the small scale features now that will really determine the magnitude and scope of the severe weather risk in Alabama early next week, but parameters certainly look favorable for the dual risk of severe thunderstorms and heavy rain.

The 12Z GFS is a little faster, suggesting the main risk of strong to severe storms will come from about 3:00 p.m. Monday through 6:00 a.m. Tuesday. This could change again, however. But, if the storms do arrive Monday afternoon or Monday evening, the instability values would be higher, and the risk more substantial.

The forecast combination of instability, shear, wind fields, and lapse rates could suggest all modes of severe weather will be possible, including large hail, damaging winds, and a few tornadoes.

BIRMINGHAM WEATHER RADIO OUTAGE: It is important to note the Birmingham NOAA Weather Radio transmitter is down, and could be down until late next week. Received this note from John DeBlock at the NWS earlier today…

“The current NOAA Weather Radio All Hazards (NWR) transmitter outage in Birmingham, AL highlights the need to have a layered approach in receiving weather notifications. The National Weather Service (NWS) recommends that no one relies on a single technology or method to receive weather warnings, and we encourage everyone to plan ahead – now – for potential severe weather in the coming days and weeks.

A good layered approach will include as many of the following options as you can employ: NOAA Weather Radio All Hazards receiver, television and/or radio broadcasts, social media, cell phone apps, and text or e-mail notification services. We are blessed with excellent broadcast and media partners across Central Alabama that work with us and local emergency management agencies to help prepare and inform the public for severe weather. Similarly, there are any number of apps and notification services available for most smartphones and devices. The NWS doesn’t endorse any particular app or service, other than the one that YOU will use to keep you and your family safe! There is a free app which was made available to all Alabamians after the April 27th outbreak, which can be found at AlabamaSafTNet.com, and many of our local broadcast and media partners offer similar free services as well. Otherwise, a partial list of available E-mail and SMS Weather Alert Services can be found at http://www.weather.gov/subscribe.”

We recommend the MyWarn and iMap WeatherRadio smart phone apps with ABC 33/40 as your chosen partner so you can watch our streaming coverage.

COLD SNAP NEXT WEEK: After the rain and storms, the weather turns much colder here Wednesday. Looks like we won’t get out of the 50s thanks to a cold core upper trough over the eastern third of the nation, and some of the colder pockets around here could visit the upper 30s by daybreak Thursday or Friday morning.

Take a few minutes to watch the Weather Xtreme video for the maps, graphics, and more details on this active weather pattern.

Beautiful Spring Day

Wed, 04/23/2014 - 06:24

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

DRY AIR TAKES OVER: The NWS in Birmingham has issued a “dense fog advisory” for much of Central Alabama this morning, but that fog will burn off quickly, and the day ahead will be delightful with sunshine in full supply along with a high in the upper 70s. The humidity will be low as dewpoints drop into the 30s.

We stay dry tomorrow; a partly sunny sky with a high up in the low 80s. It could be the warmest day so far this year for some Alabama communities.

We do note the standard “slight risk” of severe weather tomorrow from Memphis down to Shreveport, but the storms there will weaken considerably late tomorrow night as they approach and the upper support lifts out.

FRIDAY: A band of weakening showers and storms will move into Northwest Alabama late tomorrow night around midnight, and they will continue to fizzle as they move deeper into the state. Some North Alabama communities could see some rain during the pre-dawn hours Friday, but by sunrise most of the showers will be over.

The daytime hours Friday will be mostly dry with a mix of sun and clouds; the weather stays warm with a high at or just over 80 degrees.

THE ALABAMA WEEKEND: It will clearly be the warmest weekend so far this year; the GFS is suggesting highs will be up in the mid 80s both Saturday and Sunday. There will be sufficient moisture and instability for a few isolated showers both days, mostly during the afternoon and evening hours, but the chance of any one spot getting wet will be only about one in eight.

TO THE WEST: A significant severe weather outbreak will unfold across the South-Central U.S. over the weekend as a vigorous upper trough moves out of the Rockies, and a very deep surface low forms over East Colorado (983 mb). This system will encounter high to extreme instability over parts of North Texas and the Southern Plains, and all modes of severe weather will be possible. Sunday seems to be the day when severe weather parameters are maximized to the west. This is the SPC convective outlook…

ALABAMA EARLY NEXT WEEK: As you can see the “Day 6″ severe weather risk extends well into Alabama. It is important to understand we can’t be too specific about the severe weather threat six days in advance; you will hear lots of rumors floating around, but the skill in identifying mesoscale features that determine the magnitude of a severe weather threat this far out is small.

A sub-1000 mb surface low is forecast to be near St. Louis late Monday night, with a deep, negative tilt upper trough over the Great Plains. The 00Z GFS suggests the primary window for thunderstorms in Alabama will come from about 9:00 p.m. Monday through 12:00 noon Tuesday.

The good news is that the model is showing lower surface based instability values (under 750 j/kg) when the storms arrive late Monday night and early Tuesday, but the bulk shear values are very high, and the low level jet is strong (over 60 knots).

No doubt severe weather will be likely across Alabama late Monday night into Tuesday morning, with all modes of severe weather possible, but again I stress it is impossible to go into more detail this early in the game. Take a few minutes to watch the Weather Xtreme video to see all of the maps, graphics.

LATER NEXT WEEK: After the severe weather, much colder air invades Alabama Wednesday as a deep upper trough forms over the eastern U.S. Sure looks like we won’t make it out of the 50s Wednesday afternoon with lingering clouds, and some of the colder pockets over Northeast Alabama might make a run at lows in the upper 30s by Thursday or Friday morning.

AT THE BEACH: Expect mostly sunny days and fair nights tomorrow through the weekend from Panama City over to Gulf Shores. A few isolated showers could show up Friday and Saturday, but the chance of any one spot seeing rain is small. Highs along the immediate coast will be in the 68-72 degree range because of the cooler ocean water; but just a few miles inland highs will rise into the low to mid 80s. Sea water temperatures remain in the mid 60s.

WEATHER RADIO TOUR: We will be at the Publix in the McCalla/Bessemer area (just off I-459 exit one) today from 3:30 until 6:30 p.m. If you need your weather radio programmed, or have questions, or need to buy one, come see us. The Birmingham weather radio transmitter is off the air due to equipment failure, and the NWS indicates it might be 10 days or so before it gets back on the air. We can answer questions about this as well, and reprogram your radio for other frequencies that might work in your location.

Dry Air Returns Tonight

Tue, 04/22/2014 - 15:43

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

RADAR CHECK: We have a few heavy showers on radar at mid-afternoon near the I-20 corridor (Tuscaloosa to Birmingham to Anniston), but I haven’t seen any lightning strikes showing up, and it looks like thunder will be unlikely for our state this evening. Temperatures are mostly in the 68-73 degree range, and the sky is mostly cloudy.

The rain will end later this evening, and we expect a clearing sky tonight as drier air works down into the state.

TOMORROW/THURSDAY: These days look mostly sunny; we reach the mid to upper 70s tomorrow, followed by low to mid 80s Thursday. In fact, Thursday could be the warmest day so far this year for many Alabama communities.

A surface front could bring a few showers into the state Thursday night, however.

FRIDAY AND THE WEEKEND: That front will move into Central Alabama, stall, and dissipate over these three days. Bottom line is that we will continue to mention a chance of widely scattered showers Friday, Saturday, and Sunday, but the rain will be light and spotty, and the sun should be out at times. And, the weather stays warm with highs up in the low to mid 80s. A nice summer preview.

TO THE WEST: A significant severe weather event is possible this weekend over North Texas and parts of the Southern Plains… (D5 is Saturday; D6 is Sunday)…

EARLY NEXT WEEK IN ALABAMA: Still too early to really determine the threat of severe weather in our state early next week. The 12Z GFS hints the main window for thunderstorms will come from about 6:00 p.m. Monday through 6:00 a.m. Tuesday, and severe weather parameters, while not overwhelmingly strong, do suggest some risk of thunderstorms with hail and strong winds. Just too early to determine if there will be a tornado threat. See the Weather Xtreme video for the maps, graphics, and details.

LATE NEXT WEEK: Global models develop a long wave upper trough over the eastern U.S. in the April 30-May 2 time frame, which would imply temperatures well below average here in Alabama and across the Deep South. I don’t think we will have to worry about a freeze threat, but on one morning late next week there could be a touch of frost across the colder valleys and protected areas of Northeast Alabama. Again, see the video for more details.

AT THE BEACH: A few scattered showers tonight from Panama City over to Gulf Shores, but nothing too heavy or widespread. Then, mostly sunny days and fair nights tomorrow through the weekend. A few isolated showers could show up Friday and Saturday, but the chance of any one spot seeing rain is small. Highs along the immediate coast will be in the 68-72 degree range because of the cooler ocean water; but just a few miles inland highs will rise into the low to mid 80s. Sea water temperatures remain in the mid 60s.

WEATHER RADIO TOUR: We will be at the Publix in the McCalla/Bessemer area (just off I-459 exit one) tomorrow from 3:30 until 6:30 p.m. If you need your weather radio programmed, or have questions, or need to buy one, come see us.

Update on Birmingham NOAA Weather Radio Transmitter Outage

Tue, 04/22/2014 - 11:01

Yesterday, Brian posted about the Birmingham NOAA Weather Radio Transmitter being off the air. Today we received an update from Jim Stefkovich, the Meteorologist in Charge at the National Weather Service in Birmingham. Jim believes it is important for everyone to know about the situation, and has asked all media partners spread the word on the issue. Here is the latest information on this situation.

Initial issues with the Birmingham NOAA Weather Radio (NWR) transmitter occurred during the late afternoon on Saturday 4/19. Technicians determined on 4/20 that equipment on the tower, as well as cable from the transmitter to the antenna needed to be replaced. There are limited personnel available to make repairs and certified to make the approximate 450 foot climb on the antenna. We have received estimates that the transmitter may not be repaired until on or around 5/3.

They have provided a link to allow people the opportunity to switch transmitter sites and determine if they can in fact pick up broadcasts from surrounding transmitters. Map of nearby transmitters.

The last NWR weekly test occurred on 4/19. For some NWR receivers, if a weekly test does not occur within 10 days, the receiver will begin to beep constantly. This means that if not repaired by 4/29-30, these receivers will begin to beep until a weekly test is performed. It is their intention to perform a weekly test immediately if the outage lasts this long.

Occasional Showers Today

Tue, 04/22/2014 - 06:09

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

RADAR CHECK: Showers cover a decent part of North Alabama, mostly north of I-20, just before daybreak. We will continue to forecast occasional showers across Alabama today, with potential for a few thunderstorms this afternoon. The rain won’t be especially heavy, it won’t rain all day, and no severe weather is expected. Rain amounts between 1/4 and 1/2 inch are likely across North/Central Alabama.

The rain will end this evening, and the sky will clear late tonight as drier air works into the state.

TOMORROW/THURSDAY: These days will be warm and dry with a good supply of sunshine both days. The high tomorrow will be in the upper 70s, followed by low to mid 80s. Thursday could be our warmest day so far in 2014… we have hit 82 three times this year in Birmingham; the GFS is printing 83 for Thursday afternoon.

FRIDAY AND THE WEEKEND: A weak surface front will drift into Alabama, but there is very little upper support, and it looks like any showers will be few and far between Friday. Chance of any one spot getting wet Friday afternoon is only about one in five, and the high will be at or just over 80 degrees.

Very similar weather for the weekend as the front stalls out and washes out. Mixed sun and clouds Saturday and Sunday; highs in the 81-85 degree range, and only isolated showers. Most of the weekend looks rain-free for Alabama.

TO THE WEST: A significant severe weather situation is possible this weekend across parts of North Texas and the Southern Plains… in this graphic from SPC Day 5 is Saturday, and Day 6 is Sunday…

NEXT WEEK IN ALABAMA: This weather system will impact Alabama early next week; the 00Z GFS hints the main risk of showers and storms will come late Monday, Monday night, and into Tuesday morning. It remains to be seen if severe weather will be an issue here; for now the parameters look rather marginal as the main system weakens, but we are still a week out and things could change. Take some time to see the Weather Xtreme video for the maps, graphics, and details.

We also note the 00Z GFS hints at some chilly air dropping into Alabama toward the end of next week.

AT THE BEACH: A few scattered showers today from Panama City over to Gulf Shores, but nothing too heavy or widespread. Then, mostly sunny days and fair nights tomorrow through the weekend. A few isolated showers could show up Friday and Saturday, but the chance of any one spot seeing rain is small. Highs along the immediate coast will be in the 68-72 degree range because of the cooler ocean water; but just a few miles inland highs will rise into the low to mid 80s. The sea water temperature this morning at the Dauphin Island Sea Lab is 66 degrees.

WEATHER RADIO TOUR: We will be at the Publix in the McCalla/Bessemer area (just off I-459 exit one) tomorrow from 3:30 until 6:30 p.m. If you need your weather radio programmed, or have questions, or need to buy one, come see us.

WeatherBrains 430: It’s in the Can

Tue, 04/22/2014 - 05:15

WeatherBrains Episode 430 is now online (April 21, 2014). If you are crazy about weather, this is THE netcast audio program for you!

You can’t get much higher in the weather enterprise than tonight’s Guest WeatherBrain. He might well be the most powerful man in weather. He is in charge of the weather service that is the envy of the world. Officially, he is the National Oceanic and Atmospheric Administration’s Assistant Administrator for Weather Services and Director of the National Weather Service. Join us in welcoming Dr. Louis Uccellini to WeatherBrains. Our discussion with Dr. Uccellini actually took place last week in a pre-recorded interview that is airing tonight. As you might imagine, getting the schedule of this man and that of the WeatherBrains crew together was a major undertaking.

Other discussions in this weekly podcast include topics like:

  • Extremes: 102 at Death Valley, CA, and 15 at Bodie State Park, CA
  • Hurricane Conference going on in Florida
  • Severe weather ongoing in Texas
  • and more!
  • Our email bag officer is on a hot date tonight, so no mail bag segment.

    From The Weather Center:

    WeatherBrains 101: We’re going to take a look at something that most weather enthusiasts already know something about. NOAA Weather Radio is a nationwide system that provides the baseline for getting severe weather information. So we take a look at some of the basics to weather radio.

    TWIWH: Bill Murray looks back at the week of April 20th.

    Listener Surveys: Okay, we continue to drive this topic into the ground, but we really do like to hear from you. Many thanks to everyone who has taken the time to fill out the Listener Survey.

    CLOUDS THICKEN TONIGHT: It has been a dry day across the great state of Alabama today with a partly sunny sky; temperatures are generally in the upper 70s at mid-afternoon. We have noted a few echoes on radar over North Alabama this afternoon, but that is not reaching the ground.

    Clouds thicken tonight across the state, and showers will likely develop toward daybreak tomorrow.

    TOMORROW: We will continue to mention the chance of showers and thunderstorms statewide tomorrow, but it will not be an “all-day” kind of rain, the rain won’t be too heavy, and we don’t expect severe thunderstorms. Seems like the main window for rain will come from about 4:00 a.m. until 4:00 p.m; tomorrow night looks generally dry. The high tomorrow will be in the mid 70s.

    WEDNESDAY/THURSDAY: These days will be warm and dry with an upper ridge overhead; expect a good supply of sunshine both days. The high Wednesday will be close to 80, with low 80s likely Thursday. Some of the warmest weather we have experienced so far this year.

    FRIDAY AND THE WEEKEND: A weak surface front, with little upper support, will drift into Alabama Friday, and we will mention just the risk of a few widely scattered showers. The front will dissipate Saturday, and after a review of the 12Z model runs, I get the idea most the weekend will be dry and warm. Can’t totally rule out a shower somewhere Saturday or Sunday, but the chance of any one spot getting wet will be small. Looks like we stay in the low 80s over the weekend with some sun possible both days.

    To the west, the GFS hints at a significant severe weather setup for the Great Plains Sunday, but it remains to be seen if the severe weather threat will continue eastward early next week.

    We will mention a chance of showers and storms Monday and Tuesday, and significant rain is very possible along with some threat of strong storms, but we will have to wait until better model clarity to determine if severe weather will be an issue.

    AT THE BEACH: The weather looks generally good along the coast through the upcoming weekend, although a few scattered showers and storms are possible from Panama City over to Gulf Shores tomorrow. Highs along the immediate coast will be around 70 degrees, but 80 degree warmth is likely just a few miles inland. For the weekend ahead, just a slight risk of a shower Saturday, otherwise the weather looks dry on the coast. Sea water temperatures are generally running in the mid 60s along the Central Gulf Coast.

    WEATHER RADIO PROGRAMMING TOUR: This week we will be at the Publix in Bessemer, just off I-459 exit 1, Wednesday from 3:30 until 6:30 p.m. Need your radio programmed or have questions? Come see us.

This is the show all about weather featuring many familiar voices, including our meteorologists here at ABC 33/40. We will produce this week’s show tonight at 8:30 CT… you can watch it on “James Spann 24/7″ on cable systems around the state, or on the web here.

    Birmingham NOAA Weather Radio Down

    Mon, 04/21/2014 - 09:53

    The National Weather Service posted the message below this morning, so if you listen to the NOAA Weather Radio broadcast from the Birmingham transmitter, it is currently off the air. Due to the overlap in transmitter coverage, you may be able to pick up another nearby broadcast. But as noted in the message, that alternative transmitter may not broadcast warnings for your county. Fortunately, showers and perhaps an isolated thunderstorm tomorrow are not expected to be severe.

    Dry/Warm Today; Showers Return Tomorrow

    Mon, 04/21/2014 - 06:22

    An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

    CLOUDS SLOWLY INCREASING: We begin this day with temperatures mostly in the low 50s at daybreak; we rise into the upper 70s today with a partly sunny sky, although clouds will gradually increase. To the west, active weather is expected over Texas where SPC has the standard “slight risk” of severe weather up for cities like Dallas, Fort Worth, and Waco.

    TOMORROW: A surface front will bring the chance of showers and thunderstorms to the state. Thankfully there is very limited dynamic support, and severe weather is not expected. Rain amounts will be in the 1/4 to 1/2 inch range. No “all day” rain, but a few passing showers and storms are likely. The sky will be mostly cloudy, and the high will remain in the upper 70s.

    WEDNESDAY/THURSDAY: These two days will be warm and dry with a good supply of sunshine and a high up in the low 80s.

    FRIDAY AND THE WEEKEND: A weak surface boundary will move down into Alabama Friday, and could kick off a few scattered showers. But, like the system tomorrow, there isn’t much upper support for the front, and severe weather or really heavy rain isn’t expected.

    Then, for the weekend, the front will remain stationary across Central Alabama Saturday before washing out Sunday. We will keep the chance of scattered showers and storms in the forecast Saturday, but again this isn’t a “wash out” kind of rain. Then, for Sunday, just an outside risk of a shower or two during the day. Highs over the weekend will be in the 77 to 80 degree range, and the sky will be mostly cloudy both days.

    NEXT WEEK: Showers and storms will increase across the state Monday; the GFS hints the main surface low could be south of here which would mean more of a heavy rain threat… see the Weather Xtreme video for the maps, graphics, and more details.

    AT THE BEACH: The weather looks generally good along the coast through the upcoming weekend, although a few scattered showers and storms are possible from Panama City over to Gulf Shores tomorrow. Highs along the immediate coast will be around 70 degrees, but 80 degree warmth is likely just a few miles inland. For the weekend ahead, just a small risk of a shower Saturday, otherwise the weather looks dry on the coast. The sea water temperature this morning at the Dauphin Island Sea Lab is a cool 64 degrees.

    WEATHER RADIO PROGRAMMING TOUR: This week we will be at the Publix in Bessemer, just off I-459 exit 1, Wednesday from 3:30 until 6:30 p.m. Need your radio programmed or have questions? Come see us.

    My Tribute to JB

    Sun, 04/20/2014 - 14:03

    My first J.B. Elliott experience was probably in 1971. The National Weather Service in Birmingham had a recorded telephone line for the forecast. It was updated a few times a day by the meteorological technicians and forecasters that worked there at the office at 11 West Oxmoor Road in Homewood. When there was active weather, they could shorten the recording length and provide more frequent updates. One voice on the line could be counted upon to deliver excellent severe weather updates and even tropical advisory information. That was the trusted voice of J.B. Elliott.

    As a nine year old that year, I had discovered tracking hurricanes and was using my trusty World Book Atlas to plot tropical cyclone positions from the advisories. The first storm I ever tracked was Edith that September. The major hurricane came together over the southern Caribbean and reached peak intensity on September 9th before it made landfall in Nicaragua. The storm weakened considerably and meandered northwestward, eventually crossed the Yucatan Peninsula and entered the southwestern Gulf of Mexico. It moved into Mexico then tracked slowly north northeastward along the coast. On the 15th, it was picked up by an approaching trough and shunted rapidly northeastward toward the Louisiana coast. It made landfall 30 miles east of Cameron as a minimal hurricane on the morning of the 16th.

    As a fourth grader at McElwain Elementary, I begged to stay home on Thursday the 16th so that I could track the storm. It may have been the first hurricane weather day in history for a Birmingham school student. I followed the hourly observations by listening to the ATIS from the Birmingham Airport on an old Patrolman 6 VHF/UHF radio. The winds only gusted to 31 mph at BHM, but I recorded the reports diligently like it was a category five hurricane. 1.94 inches of rain fell at the Airport.

    By the next year though, I was addicted to the reports on the recorded line. There was no Weather Channel, no internet, no weather radio, and barely any television weather. And you knew that it was going to be a good weather information day when you heard that reassuring voice.

    But I didn’t know who it belonged to. It would be 1976 before I would meet the man behind the voice at the NWS. And in November of that year, NOAA Weather Radio came to Birmingham. Then it was on! J.B. quickly established himself as the trusted voice for Central Alabama weather on the new KIH-54 station.

    Anytime there was active weather, you hoped J.B. was working. You knew then that you were in good hands for the next 8 hours or so. That never was truer than on April 4, 1977. I was the only kid at Huffman High School who carried a NOAA Weather Radio to school. I knew that we had trouble when a tornado warning was issued shortly before 3 p.m., which was dismissal time. I went up to the teacher and told her that a warning had been issued and that we needed to let someone know so that we could sound the tornado drill bell. She told me to sit down.

    The rear flank downdraft struck with a fury even as the dismissal bell sounded. I hit the hallway running, but could not open the glass doors. The tornado bells sounded immediately afterwards and we were all hurried downstairs. The storm passed well to the north of us and we were allowed to leave. J.B. was broadcasting live on KIH-54, the first of several times that would happen under his watch.

    J.B. would bolster his image as a weather legend with his updates that afternoon and over the next twelve years. Any event that warranted reports on the “Alabama Weather Situation” immediately got your attention. He would continue to be the voice of NOAA Weatheradio for everyone in Central Alabama until his retirement in 1989. The article that ran in The Birmingham News when he retired is shown here.

    But that would not be the end of his storied career. He has been creating content for The Weather Company (now known as The Weather Factory) ever since. And while he has officially retired from his day to day forecasting duties, he still is an owner in the company. He has his logon for AlabamaWx and he promises you will see occasional stories under his byline in coming days. He will also make an appearance on WeatherBrains from time.

    Sally and I went out to J.B. and Judy’s house last Thursday to take them a set of birthday cupcakes. J.B. was funny and said thank you to everyone for his birthday wishes. M&M were in rare form as well.

    Thank you J.B. for your years of service to the people of Alabama, your mentoring and your friendship. You are an Alabama Weather Legend.

    Sunday Update

    Sun, 04/20/2014 - 10:36

    The tale of two skies continues across the state of Alabama on this Easter Sunday.

    Skies are cloudy south of I-85 and US-80 over the southeastern part of the state when some moisture is riding up and over the high pressure over southern Alabama. Funny thing, the moisture is coming from an unusual direction: the northeast. The culprit is the large low off the coast of the Carolinas. Elsewhere, skies are a bright blue.

    The closest rain to Alabama is some showers along the Carolina Coast. Just a little further away, we find some showers and storms over Texas and Oklahoma ahead of our next weather system.

    Temperatures this afternoon across Central Alabama will be in the 76-79F range with a few readings touching 80F as the clouds stay well to the south and gradually erode. Lows tonight will be near 50F.

    Gorgeous Easter Sunday

    Sun, 04/20/2014 - 07:10

    An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

    As Ryan Stinnett noted in the forecast this morning, you could not order a better day than what we expect to see across Central Alabama today. Sunshine will be in full supply and we expect the afternoon highs to climb into the middle and upper 70s with comfortably low humidity to add to the wonderful conditions.

    Monday will be a transition day as we see clouds increase ahead of the next front approaching the area from the northwest. That front should move into and across Central Alabama Tuesday bringing us showers and perhaps a little thunder. Moisture appears to be somewhat limited, so while the likelihood of showers is very high, the scattered nature of them will mean that some folks won’t get wet at all and some could see a half inch of rain. The surface and upper level low that moved off the Southeast US coast yesterday will help to keep a strong southerly return flow from developing thus limiting the amount of moisture available. But moisture will be sufficient for scattered showers as precipitable water values climb close to 1.5 inches.

    Cool 500 millibar temperatures on Tuesday could help to produce thunderstorms with hail. Instability values are somewhat marginal for really strong updrafts, so I do not expect to see any organized severe weather.

    The upper trough moves quickly east allowing an upper ridge to build into the eastern third of the country. This will dry us out for Wednesday and Thursday. But while the air mass will be drier, we won’t see any appreciable lowering of the temperatures with a limited northwesterly flow that does not go very far north, so no real air mass change.

    The big forecast problem will be dealing with the end of the week and into the weekend. The GFS keeps the ridge fairly strong so that the traveling weather systems are expected to remain well north of us. That puts us into a weakened pattern where the fronts will drag into the area with sufficient moisture for scattered showers driven primarily by daytime heating. While the best chance for showers appears to come on Friday, the front becomes stationary in the area keeping us susceptible to scattered showers into the weekend. Without a strong push, the front is not likely to bring much in the way of an air mass change so temperatures will remain warm with highs around 80 or so.

    Looking out into voodoo country, the GFS had a really strong Omega ridge developing at the end of April. While the pattern remains similar, the latest GFS run is more realistic in the look of the ridge. A strong upper trough approaches the eastern US on May 1, which could signal a round of severe storms for the Southeast US. By May 5th, the GFS shows the westerlies well north of us putting us into the same issue of fronts dragging into the area without much strength.

    And you can follow news and weather updates from ABC 33/40 on Twitter here. Stay in the know by following the whole gang – here’s the list…

    Early Afternoon Update

    Sat, 04/19/2014 - 13:31

    Another fascinating look at the storm system to our southeast today. The surface low and upper-level low are both located on the Georgia/Florida line this afternoon. Clouds and rain continue to fall in many areas to our east with this system. The last few satellite images it appears to look like the clouds are bubbling up over southeastern Georgia. These are actually thunderstorms that have developed in the area and the strong updrafts in the storms are allowing the cloud tops to make it higher than the lower cumulus and stratus clouds affecting most areas.

    For us in Alabama, if you are west of Interstate 65, there is hardly a cloud in the sky as beautiful blues skies are allowing an abundance of sunshine through. East of Interstate 65, there is a mix of sun and clouds, which becomes more overcast the farther east you go. There are still a few very light showers showing up on radar this afternoon east of I-65 and south of I-20.

    Where the clouds and rain are, it is quite a cool and raw day. Temps are staying in the 50s across much of Georgia and the Carolinas, with even some 40s in North Carolina. Where the sun is out over most of Alabama, temps are well into the 70s and it has turned out to be a beautiful spring Saturday. At last check I noticed the temperature at Auburn was 59 degrees verses the 77 in Tuscaloosa.

    For the rest of today, these lows will continue to slowly shift off to the east and will gradually allow skies to clear over eastern portions of the state later this evening.

    A Mix of Sun and Clouds

    Sat, 04/19/2014 - 10:28

    Many areas of Alabama are seeing a mix of sun and clouds late this morning thanks to the upper-level low that is currently over Georgia. There is quite a bit of sunshine across much of Central Alabama this morning as well as a brisk north wind in most locations.

    Up and down the western side of the state, there is nearly full sunshine along Highway 43 from Muscle Shoals to Mobile. Along the Interstate 65 corridor in Central Alabama, clouds are moving towards the south and are thinning out slowly. The main area of clouds over the state is confined to the southeastern corner of the state. Locations in and around Dothan, Eufaula, Phenix City, Troy, Hartford, and Fort Rucker continue to see mostly cloudy and overcast conditions.

    As we head through the rest of today, we will continue to see the clouds slowly clearing out of the state as the upper-level low pulls away from the region. Most locations will see mostly sunny skies later today. Then for Easter Sunday, nothing but sunshine and blue skies are expected. .

    Rainfall Summary

    Sat, 04/19/2014 - 07:56

    Here is a summary of the rainfall from a variety of reporting stations for the last 48 hours as prepared by the National Weather Service in Birmingham. As you can see from the observed totals, there was a pretty steep gradient in rainfall amounts from Jefferson County southeastward toward Dothan with Barbour County coming in with totals approaching 5 inches.

    The overall weather pattern continues to be an active one, but I sure would not classify this month as your typical April! The high temperature at the Birmingham Shuttlesworth International Airport yesterday barely made it out of the 50s with a 61 which is 14 degrees below our seasonal average for this date. The low for the day was only 1 degree above, so we saw very little diurnal change in the temperature. Plus we got a bit more rain bringing us to a total which is nearly 4 inches above the 30-year average rainfall for the month – with 11 days still left to go.

    The surface low along with the upper level cold core low which brought us the soaking rain yesterday continues to bring rain to much of the eastern half of Alabama this morning. Both lows should continue to push eastward, so we should see a slow decrease in the light rain which is now falling over areas generally east of Interstate 65. Temperatures will be problematic with lower 70s possible from Birmingham westward while areas east of Birmingham could remain shrouded in clouds holding temperatures in the 60s.

    Surface high pressure will fill in behind the surface and upper lows on Sunday bringing us a beautiful Easter Sunday. We’ll see a few late morning and afternoon clouds, but the sunshine will feel good with temperatures climbing into the middle 70s for most of us.

    Monday will be a transitional day with clouds on the increase ahead of the next upper trough and surface cold front. The front should pass through Central Alabama on Tuesday bringing us the next good chance of showers. The afternoon highs should reach the upper 70s. The front should move through briskly as the upper trough moves quickly off the East Coast and we come under ridging aloft for Wednesday and Thursday. Yet another strong upper trough approaches Alabama on Thursday and Friday bringing another cold front into the picture. Timing of this system seems to befuddle the models as the GFS has continued to oscillate back and forth between Friday and Saturday on the frontal passage and attendant rain chances. The GFS is also more aggressive with the rain chances and the amounts than the European, so the forecast remains somewhat fluid at the moment. But whether it is Friday or Saturday, it looks like we’ll have a reasonably good chance at some showers before clearing out for next Sunday. Temperatures appear to be seasonal with highs in the upper 70s and morning lows mainly in the 50s.

    Looking into voodoo country, I’d describe the model solutions as complex. Another shot at rain comes around the 29th and then the GFS goes off the scale with a huge Omega block ridge situated along the Mississippi River. The ridge is so strong it does seem exaggerated, so my confidence in the solution is pretty low. The Omega ridge pattern evolves by May 4th with a trough undercutting the huge ridge. Definitely a stay tuned on this one situation.
