Loud Storms Across Central Alabama

ABC 33/40 Weather Blog - 3 hours 49 min ago

Several strong storms continue this morning across Central Alabama. These storms are producing heavy rainfall, small hail, gusty winds, frequent lightning, and window shaking thunder. Numerous reports across the area of the very loud thunder associated with this morning’s storms. All storms remain below severe limits at this time.

The activity continues to slide off to the east and the more intense storms remain south of Interstate 20. Locations in Bibb, Chilton, Hale, and Greene Counties are seeing the worst of the weather right now. The storms continue to slowly weaken as the move through the area.

Strong Storm for Pickens County

ABC 33/40 Weather Blog - Thu, 04/24/2014 - 22:36

Showers and storms are now moving into the state. Even though this cell has been severe, it continues to weaken as it moves east. The NWS in Birmingham has decided not to issue a warning for this storm at this time.

It will be producing gusty winds and some hail, and these should stay below severe criteria, but expect very heavy rainfall and frequent lightning. This storm will be affecting locations across southern Pickens County affecting Pickensville and Aliceville.

…SIGNIFICANT WEATHER ADVISORY FOR SOUTHERN PICKENS COUNTY UNTIL
1115 PM CDT…

AT 1023 PM CDT…THE NATIONAL WEATHER SERVICE WAS TRACKING A STRONG
THUNDERSTORM 12 MILES NORTHWEST OF PANOLA…OR 14 MILES SOUTHWEST OF

Strong Storms Approaching West Alabama

ABC 33/40 Weather Blog - Thu, 04/24/2014 - 21:12

Strong and a few severe storms continue to move across northern Mississippi this evening. These storms will be entering into Alabama over the new couple of hours. The storms are moving-in a few hours earlier than originally forecast and are maintaining some very strong updrafts. This could allow for some of the storms to maintain severe criteria as the enter the state and could still pack a bunch into western portions of Alabama.

With the ongoing severe storms moving in, the SPC considered extending the severe thunderstorm watch currently over Mississippi, into the first few rows of counties in West Alabama. After a discussion with SPC, the NWS in Birmingham decided not to issue a watch for Alabama. Dew points and instability are much lower in Alabama than in Mississippi. The storms will continue to weaken as they head east, but portions of West Alabama could see hail and gusty winds.

Evening Update

ABC 33/40 Weather Blog - Thu, 04/24/2014 - 20:01

First off there is a very dangerous tornado warned storm moving across Central Mississippi. The NWS in Jackson is tracking a confirmed tornado well north of Jackson and northeast of Yazoo City. The storm currently is in Holmes County near the town of Lexington as is approaching Interstate 55. This storm continues to move off to the east-southeast and besides producing the tornado, hail to the size of golf balls is possible.

Click image to enlarge.

For us in Alabama, we will continue to watch the storms to our west, but the atmosphere over Alabama is more stable than over Mississippi. Instability values are higher to our west as dew points are in the mid 60s. Over Alabama there are only in the mid-50s, which are not ideal for severe storms. We are expecting the storms to be weakening as they approach the state later tonight.

The SPC maintains portions of Northwest Alabama in a slight risk for severe weather. The areas outlined in green remain under this risk until 7 AM tomorrow morning. Locations from northern Pickens County, up through Fayette, Winston, Morgan, and Limestone Counties, and areas to the north and west are in this threat. As the storms approach the state, we could see some of them produce some hail and gusty winds.

Showers Early Tomorrow; Very Warm Weekend Ahead

ABC 33/40 Weather Blog - Thu, 04/24/2014 - 14:27

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: Nothing on radar over Alabama this afternoon; the sky is partly sunny and temperatures are generally in the low 80s. We do note strong storms forming over much of Arkansas, where a severe thunderstorm watch has been issued.

A band of showers and thunderstorms will enter the northwest corner of our state around midnight tonight; they could pack a punch initially as they impact places like Muscle Shoals and Russellville, but the storms will weaken rapidly as they move deeper into Alabama during the pre-dawn hours tomorrow. Just a few scattered showers are likely for Birmingham, Tuscaloosa, Anniston, and Gadsden between 3:00 and 8:00 a.m.

TOMORROW THROUGH THE WEEKEND: Once those early morning showers end, tomorrow will be a mostly sunny day with a high between 77 and 80 degrees.

Look for the warmest weather so far this year over the weekend; a good supply of sunshine Saturday and Sunday with highs up in the mid 80s… a nice summer preview. High clouds will begin to increase Sunday afternoon ahead of storms west of Alabama.

SPC maintains severe weather risks for Sunday and Monday… the threat Sunday is west of our state, but much of Alabama is included in the Monday risk.

THE ALABAMA SEVERE WEATHER THREAT: The new 12Z global model runs are slower, suggesting the main action will come late Monday night and during the day Tuesday. With a slow moving, cut off upper system like this, the slower solution is probably correct, and it could very well be Tuesday before we have our primary severe weather threat in Alabama.

As we have discussed here this week, it is simply too early to be able to identify the mesoscale features of this system that will ultimately determine the magnitude of the severe weather threat. Seems like the severe weather parameters are maximized west of Alabama Sunday… no doubt we will have some risk of severe weather here, but the shear, instability, and wind fields are not exactly “overwhelming”, and it could very well be that flooding is the primary impact.

A very slow moving band of storms, feeding off very high precipitable water values, will bring rain amounts of 2 to 4 inches to North Alabama, and some flooding problems are very possible. It might be late Tuesday night, or even Wednesday before the rain gets out of here.

We will be able to be much more specific about the timing, and the modes of severe weather to expect tomorrow morning. But I really do think the slower idea has very good credibility, so our biggest day could very well work out to be Tuesday.

See the Weather Xtreme video for the maps, graphics, and more details.

COOLER AIR FOLLOWS THE RAIN: Models have backed off on the strength of the upper trough over the eastern U.S. over the latter half of next week, and also on the amount of cool air that reaches Alabama. Highs could drop into the 60s by Thursday and Friday.

WEATHER RADIO UPDATE: Important note concerning the Birmingham NOAA Weather Radio situation…

NWS technicians have successfully installed a temporary fix to the Birmingham transmitter. While not returning to full power and coverage, we hope that this fix will provide coverage to a good number of radios that may not have been able to receive a sufficient signal from a backup transmitter. There are technical issues as to the type and length of cable, as well as the height of the tower that will limit our capabilities until the permanent replacement can be installed. We are still hoping to have that happen on or about May 3rd.

To allow NWR Birmingham radio users to check/confirm reception on their radios, we will be conducting tone alert tests on the BIRMINGHAM TRANSMITTER ONLY at 6 PM CDT tonight (Thurday), and again at 11 AM and 6 PM CDT Friday and Saturday. For all other transmitters, we will conduct the regularly scheduled weekly test Saturday at 11 AM CDT. If NWR listeners receive the test signal, their radios should activate for any warnings that are issued. Note that not all weather radios are configured to alarm for the weekly test; users may need to be near their radios at those times to confirm receipt of the test signal. If they do not receive the test signal from the Birmingham transmitter, they may need to reprogram their radios to one of the backup transmitters. Our webpage has all the specific information needed to do that.

At this point, we do not anticipate any significant changes to the status of the transmitter in the near term. We truly appreciate all the offers to assist us in fixing the tower, however, we are bound to existing contracts and the Federal contracting regulations for the maintenance and repair of the transmitters. While it is highly unlikely, if anything changes in that regard, we will let everyone know.

GULF COAST WEATHER: Look for sunny days and fair nights through Monday… showers and storms return Tuesday and Wednesday of next week. Highs on the immediate coast will be in the low 70s, but 80s are likely just a few miles inland. The sea water temperature at the Dauphin Island Sea Lab this afternoon is up to 71 degrees.

Risk for Severe Weather for Parts of NW Alabama

ABC 33/40 Weather Blog - Thu, 04/24/2014 - 13:18

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

ABC 33/40 Weather Blog - Thu, 04/24/2014 - 12:08

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

ABC 33/40 Weather Blog - Thu, 04/24/2014 - 06:35

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

ABC 33/40 Weather Blog - 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

ABC 33/40 Weather Blog - 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

ABC 33/40 Weather Blog - 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

ABC 33/40 Weather Blog - 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

ABC 33/40 Weather Blog - 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.
