Messy Rush Hour

Fri, 04/10/2015 - 07:06

It is a messy rush hour across a large part of the Birmingham Metro area this morning with torrential rain falling from thunderstorms.

Rain is heaviest across the southern part of the Metro, especially along I-459 to the west of I-65 and over much of the area east of I-65.

The left panel shows the current radar. The right panel shows the rainfall which has fallen over the past hour. Rainfall rates of over an inch per hour have occurred. 1.34 inches of rain fell at the Birmingham Airport in just one hour.

This has resulted in minor flooding on some roadways, slowing traffic and causing accidents. The NWS has issued an Areal Flood Advisory for parts of Jefferson County.

Slow down and plan for a longer commute this morning.

Wet At Times Today; Drier Tomorrow

Fri, 04/10/2015 - 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: As expected, showers and storms have remained well under severe limits across North Alabama during the pre-dawn hours as the main upper support lifted away to the northeast.

A cold front will push slowly through the state today; showers and thunderstorms are likely this morning statewide, but by this afternoon the most numerous storms will push down into the southern half of Alabama. The guys at SPC maintain the standard “slight” risk of severe weather for South Alabama this afternoon and early tonight…

Some of the storms across South Alabama could produce hail and gusty winds this afternoon, but with little low level bulk shear and weak wind fields, there is very little risk of a tornado.

THE ALABAMA WEEKEND: Tomorrow promises to be a beautiful day for the northern half of the state with ample sunshine and a high in the mid 70s. Humidity values will be lower, and we start the day close to 50 degrees. The weather stays dry Sunday for North/Central Alabama, but clouds will begin to increase during the afternoon hours, and a shower could move up in here from the south Sunday night as moisture returns. Sunday’s high will be in the 76-79 degree range.

NEXT WEEK: Showers and storms are likely Monday as a short wave passes through; showers will be fewer in number Tuesday, but rain is still possible at times. Unsettled weather continues for the rest of the week with some risk of showers and storms daily; the 00Z GFS hints that we could see a setup for strong to severe storms late in the week with a surface low setting up over Arkansas with good upper support. See the Weather Xtreme video for maps, graphics, and more details.

AT THE BEACH: For the weekend, we project about 2 to 4 hours of sunshine for the coast from Panama City west to Gulf Shores with a few scattered showers and thunderstorms both days. Then, early next week, about 3 to 5 hours of sun daily, and we will maintain the risk of a few passing showers and storms daily Monday through Wednesday. Highs will be in the 70s, and sea water temperatures are very close to 70 degrees.

Storms Remain Below Severe Limits

Fri, 04/10/2015 - 05:01

Thunderstorms continue to move through North Alabama this morning… some with heavy rain and lots of lightning, but they remain well below severe limits.

Storms will continue to move southeast during the next few hours. Later today, a few severe storms are possible over the southern half of the state, where hail and gusty winds will be the primary threat. A full forecast discussion and new Weather Xtreme video coming soon…

The Alabama Weather Situation at 11:30 p.m.

Thu, 04/09/2015 - 23:35

Click to enlarge

We continue to monitor active weather to our northwest late tonight as a cold front pushes towards Alabama.

The front is about 75 miles northwest of Little Rock at this hour. It will be near Hamilton by 7 a.m. and south of I-59 by noon.

Showers and storms continue across northern Mississippi and eastern Arkansas tonight, but they are not severe. Instability values are dropping across Alabama and low level wind shear values are low. The storms will continue to run out of steam as they push east of I-55 in Mississippi during the early morning hours and move into Northwest Alabama.

There is a severe thunderstorm watch for northern Mississippi that goes until 1 a.m. It remains to be seen whether the NWS will issue a new watch downstream into Alabama. My gut feel is that they won’t.

We can’t rule out a severe storm or two overnight, with damaging wind gusts the main threat, so we will be monitoring things closely through the overnight hours.

Watching Developments To The Northwest

Thu, 04/09/2015 - 21:14

A major tornado moved through Rochelle, IL this evening… part of a wide area of strong to severe storms from the Great Lakes to Texas…

Strong storms are over Arkansas and West Tennessee… and those are moving in our direction…

A severe thunderstorm watch is up for much of North Mississippi, but no watches are in effect for any part of Alabama at this point. The high resolution HRRR model shows the storms moving into the northwest corner of Alabama between 1:00 and 2:00 a.m.

The storms will be strong as they move into the northwest corner of Alabama, with potential for some hail and strong gusty winds. But, with the main dynamics lifting our to the northeast, and weakening wind fields, the storms should weaken as they move south during the pre-dawn hours, and the severe weather threat is low for places like Birmingham, Tuscaloosa, Anniston, and Gadsden.

Storms could intensify again tomorrow afternoon over South Alabama, but the tornado threat looks very low… main issues could be from hail and gusty winds. Drier air rolls into the state tomorrow night, and the weekend will be dry and pleasant. We will watch radar trends closely overnight as the storms get closer.

Showers/Storms Arrive Tomorrow

Thu, 04/09/2015 - 15:26

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.

WARM APRIL AFTERNOON: Temperatures are generally in the 80-84 degree range across the great state of Alabama this afternoon with a mix of sun and clouds; nothing showing up on radar. The weather is getting active north and west of the state; a tornado watch is up for parts of Texas, Arkansas, Louisiana… and to the north another one is in effect for much of Illinois and some of the adjacent states, including Chicago.

A large “enhanced” severe weather risk continues from the southern Great Lakes down to the Ark-La-Tex region through tonight…

Note the “slight” risk extends down into far Northwest Alabama… and keep in mind this outlook runs through 7:00 a.m. tomorrow.

SHOWERS AND STORMS INTO ALABAMA: A line of strong, possibly severe storms will enter the northwest corner of the state between 1:00 and 3:00 a.m… and they could produce hail and strong winds as they move through places like Florence and Muscle Shoals.

But, the storms should weaken as they drop south toward daybreak, and it continue to look like the chance of severe weather is low for places like Birmingham, Tuscaloosa, Anniston, and Gadsden.

But, SPC has a “slight” severe weather risk up tomorrow afternoon for the southern counties of the state… instability values will be higher there, and some of the storms from U.S. 80 south (Demopolis to Selma to Montgomery to Opelika) could produce hail and gusty winds. The tornado threat is very low for South Alabama tomorrow afternoon despite the SPC risk due to weak wind fields and low bulk shear values.

THE ALABAMA WEEKEND: Still looking very nice for most of the state; for North/Central Alabama Saturday will feature a sun-filled sky with lower humidity and a high in the mid 70s. And, we stay dry Sunday with a partly to mostly sunny sky along with a high in the upper 70s. Any showers over the weekend will be confined to far South Alabama, and even there those showers will be widely spaced.

NEXT WEEK: Moisture comes back, and it looks like we will have some risk of showers and thunderstorms on daily basis through the week; a deep upper trough could bring the risk of strong to severe storms around Thursday (April 16)… but too early to be specific on that risk. See the Weather Xtreme video for maps, graphics, and more details.

AT THE BEACH: Expect about 2 to 4 hours of sunshine on the Gulf Coast from Panama City west to Gulf Shores tomorrow and Saturday with a few passing showers and thunderstorms likely. Then, 5 to 7 hours of sunshine Sunday into early next week with scattered showers and storms possible. Highs on the immediate coast will be mostly in the 70s, and the sea water temperature this afternoon at the Dauphin Island Sea Lab is 71 degrees.

Cold Front Arrives Tomorrow

Thu, 04/09/2015 - 06:20

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.

ANOTHER WARM DAY AHEAD: Yesterday gave Alabama quite the summer preview… some highs included 89 at Dothan, 88 at Troy, and 87 at Anniston and Montgomery. We project a high today in the low to mid 80s for most North/Central Alabama communities with a mix of sun and clouds; the chance of an afternoon shower for any one given spot remains small.

NORTHWEST OF ALABAMA: There is a large “enhanced” risk of severe weather from near Shreveport to Chicago…

These storms will move into the northwest corner of Alabama after midnight; SPC has that little part of Alabama (around Muscle Shoals) in the standard “slight risk” of severe storms for the potential of strong gusty winds and some hail. However, the storms should weaken as they move deeper into Alabama toward daybreak tomorrow.

FRIDAY FRONT: Models have trended a little slower with the movement of the surface front tomorrow. The day will be cloudy with a good chance of showers and a few thunderstorms; SPC has the southern third of the state in the standard “slight” risk of severe weather tomorrow afternoon as there will be a decent amount of instability. But, overall wind fields are weak and the threat looks fairly limited.

In terms of timing, with the slower movement of the front I think we need to maintain at least a chance of showers into the afternoon hours for North/Central Alabama (places like Birmingham, Tuscaloosa, Anniston, and Gadsden). Showers will end during the evening as drier air drops in from the north. Tomorrow’s high will be in the mid to upper 70s.

THE WEEKEND: Saturday looks like a delightful day for the northern two-thirds of the state with ample sunshine and a high in the low to mid 70s. Humidity values will also be considerably lower. The dry air should hold in place Sunday for the northern counties, but showers will be possible from about Montgomery south Sunday afternoon.

NEXT WEEK: Scattered showers and storms are possible statewide Monday as a southerly flow becomes established again, and it looks like there will be some risk of rain every day next week as the moist air stays in place. For now we don’t see any overwhelming evidence of severe weather problems in Alabama, but we always have to watch trends closely this time of the year. Highs next week will be generally in the 75-80 degree range, not far from average values for mid-April in Alabama. See the Weather Xtreme video for maps, graphics, and more details.

Cold Front Arrives Friday Morning

Wed, 04/08/2015 - 15:41

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.

WARM APRIL AFTERNOON: As expected, it is a very warm April day across the great state of Alabama with most communities up in the low to mid 80s. Interesting to note Tuscaloosa is cooler with temperatures only in the mid 70s; a small but persistent patch of clouds has lingered right over the Druid City through the day. No rain on radar, and the chance of showers will remain very low overnight.

NORTH AND WEST OF HERE: A “moderate” severe weather risk is up for parts of Oklahoma, Kansas, and Missouri, and severe storms with tornadoes will remain possible in that region.

TOMORROW/FRIDAY: Our weather won’t change much tomorrow… mostly dry and warm with only isolated afternoon showers or storms. The surface low, partly responsible for the severe weather across the nation’s mid-section, will lift north toward Canada tomorrow night and Friday, and will drag a cold front into Alabama.

Showers and storms ahead of the front will enter far North Alabama after midnight tomorrow night, and they could pack a punch initially over the Tennessee Valley. SPC has pulled the “slight risk” of severe weather down into extreme North Alabama due to this potential; places like Muscle Shoals and Athens could see storms with some hail and strong, gusty straight line winds between 2:00 and 6:00 a.m. Friday.

Then, during the day Friday, the storms will weaken as they move southward, and severe weather is not expected for places like Birmingham, Tuscaloosa, Anniston, and Gadsden. The best chance of showers and storms will come during the morning hours, with drier air moving in by Friday afternoon. Friday’s high will drop back into the 70s due to the clouds and rain.

THE ALABAMA WEEKEND: It looks delightful for the northern two-thirds of the state, with sunny pleasant days and clear cool nights. The high Saturday will be in the mid 70s, and then close to 80 degrees Sunday afternoon. Morning lows will be well down in the 50s, with 40s for the colder valleys. Any showers will be confined to far South Alabama, and even there rain won’t be too widespread or heavy.

NEXT WEEK: Moisture begins to return, and we will deal with some risk of showers Monday and Tuesday, but the best dynamic support for severe weather will remain north and west of Alabama. See the Weather Xtreme video for maps, graphics, and more details.

Warm And Mostly Dry Today

Wed, 04/08/2015 - 06:12

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.

SUMMER PREVIEW: We are projecting a high in the mid 80s across much of North/Central Alabama today… making it one of the warmest days so far this year, and well above the average high of 72 degrees for April 8 (for Birmingham). The sky will be partly sunny, and the chance of any one spot seeing a shower this afternoon is only about one in ten.

While we enjoy the calm weather, severe storms are likely later today and tonight across parts of Oklahoma, Kansas, and Missouri, where SPC has defined an “enhanced” severe weather threat.

Not much change tomorrow; there is an “enhanced” severe weather threat from near Chicago down to below St. Louis, but in Alabama the day will be warm with only widely scattered afternoon showers or storms; we reach the low to mid 80s tomorrow afternoon with a mix of sun and clouds.

FRIDAY FRONT: The surface low, partly responsible for the active weather across the nation’s mid-section today and tomorrow, will move up into eastern Canada, dragging a cold front into Alabama Friday. Data from the high resolution NAM hints the main band of showers and storms ahead of the front will impact North/Central Alabama from 4:00 a.m. until 12:00 noon Friday. The severe weather potential continues to look very low; SPC has a “marginal” severe weather risk defined for the southern two-thirds of the state.

Instability values are marginal, bulk shear is low, wind fields are weak, and lapse rates are not especially steep. You have to watch any thunderstorm in April in Alabama, but it just doesn’t look like a severe weather setup. Rain amounts around 1/2 inch are likely.

THE ALABAMA WEEKEND: Global models continue to trend dry for the northern half of the state. Saturday now looks mostly sunny with a high in the 70s… any showers should be confined to far South Alabama. And, while moisture begins to return Sunday, the 00Z GFS is pretty dry with only a small threat of shower for the northern counties. The high Sunday afternoon will be close to 80 degrees.

Next week scattered showers and storms are possible Monday through Wednesday, but again the best chance of organized severe weather seems to stay well to the north and west of Alabama, where better dynamic support exists. See the Weather Xtreme video for the maps, graphics, and more details.

ON THIS DATE IN 1998: An EF-5 tornado cut through the western suburbs of Birmingham… communities like Oak Grove, Rock Creek, Sylvan Springs, McDonald Chapel, Edgewater, and Pratt City killing 32 people. The same parent thunderstorm dropped another tornado in St. Clair County, killing two north of Pell City.
