Stormy Sunday into Monday

***Note: while in production of the morning video a tornado watch was issued for Southeast Alabama and the Florida Panhandle. ***

A large cluster of storms was moving across Central Alabama early this morning. This cluster is adding additional complexity to the forecast today as it helps to stabilize the atmosphere across the state. Stronger storms were noted across extreme South Alabama. Once these storms move east, we should have a lull in the action until the upper level storm system to our northwest brings a final round of potentially severe storms to the area.

Lots of questions this morning on exactly how both the storms along the Gulf Coast as well as the large rain cluster moving through Central Alabama will affect the weather later today. SPC still has an enhanced area outlooked just to our west and all of Alabama remained in a standard slight risk area. It’s worth noting that the GFS MOS numbers for probability are also down for the day and only peak around 40 percent for early Monday morning. In other words, the models are struggling, too.

Since the early morning convection will be gone by mid to late morning, I expect the atmosphere will have enough time to recover as the GFS paints a broad area of CAPE values over 1,500 j/kg for the afternoon hours. Plus we have the mesoscale convective system that should be moving through the area. While the tornado threat is not zero, the helicity and bulk shear numbers don’t seem to be that impressive. The final round of severe potential will come as the cold front approaches late tonight and into early Monday morning, but by then the atmosphere will be worked over a good deal and with the best dynamics lifting well to our north, the storms will probably be weakening though still the potential for damaging wind and some large hail.

The upper air pattern evolves into a broad trough over the eastern half of the country on Tuesday and Wednesday as surface high pressure settles into the region and provides a couple of very nice Spring days. But the good weather does not last long as another front approaches on Thursday and an upper level trough heads our way Friday and Saturday keeping the weather unsettled for Alabama and the Southeast US.

Wet this morning at the beach, but beach goers should see a lull for the late morning and early afternoon before additional storms occur. Highs will be in the upper 70s. Looks like some nice beach weather for midweek.

Severe Storms Possible Later Tonight/Tonight

ABC 33/40 Weather Blog - Sun, 04/19/2015 - 06:19

Brian will be along shortly with a new Weather Xtreme video… this is a look at what to expect over the next 24 hours.

RIGHT NOW: Rain and storms continue over much of North/Central Alabama this morning with heavy rain in spots. Organized severe weather is not expected over the northern half of the state, and this activity will slowly diminish later this morning. We should note severe storms are possible over South Alabama this morning; in fact SPC has issued a tornado watch much of Southeast Alabama until 3:00 this afternoon.

LATER TODAY AND TONIGHT: SPC has all of Alabama in the standard “slight risk” of severe weather…

Seems like we have two potential windows for severe storms.

One will come this afternoon when a disturbance (MCV) approaches from the west, and instability reaches a peak (ML CAPE values over 1,500 j/kg). Bulk shear values are not too impressive, and the tornado threat seems low. But, stronger storms during the afternoon could produce hail, and strong straight line winds where bowing segments develop.

Then, late tonight, more storms are likely ahead of the surface cold front. Most of this will come from about midnight tonight through 6:00 a.m. tomorrow. While there will be an increase in the low level jet (winds about 5,000 feet off the ground), the air will be pretty worked over across Alabama from previous storms, and the core dynamic support will lift northeast, away from us. A good chance the storms will weaken as they move through, but there still is some risk of a few storms with hail and gusty winds. The tornado threat late tonight is not zero, but very low.

And, don’t forget… when it comes to thunderstorms, expect the unexpected, so we will keep a very close eye on thunderstorm/radar trends today and tonight. Stay tuned for updates.

Wet/Stormy Late Tonight

ABC 33/40 Weather Blog - Sat, 04/18/2015 - 20:20

Rain continues to increase over West and Southwest Alabama tonight… this big rain mass is moving northeast.

Animation of the high resolution HRRR model shows a very wet overnight period for our state…

The main threat overnight will be heavy rain and localized flooding issues… just a marginal severe weather threat. A few storms could produce small hail and gusty winds.

We will have a break in the rain from mid-morning tomorrow through the evening hours, but another band of showers and storms will move in tomorrow night and early Monday, and those could be strong to severe. More later… stay tuned…

Lull Today, Active Sunday

ABC 33/40 Weather Blog - Sat, 04/18/2015 - 13:20

Though it remains cloudy, gray, and cool today, we are not seeing much in the way of rain across the state this afternoon, but of course that will be changing as rain and storms will return to the state as early as this evening. Temperatures this afternoon are in the upper 60s and lower 70s for most of Central Alabama. The SPC does have much of the southern two-thirds of the state outlined in a “marginal” risk for severe weather today, notice the blue line in the map below. Areas along and south of a line from Fayette to Birmingham to Talladega are included in this risk and this will be for storms that arrive late tonight into the pre-dawn hours.

I want to say first off that there is a lot of uncertainty with both rounds of potential storms we could see. The first round will come overnight tonight. Model data suggests showers and storms will begin developing across Mississippi and Alabama this afternoon and this activity will be heading towards Central Alabama during the overnight hours, with the main time frame being from around 12 a.m. until 8 a.m. tomorrow. We will see more of a heavy rain event with limited instability, but there will be still be the threat of storms that will bring with them the threat of hail and strong gusty winds, and while the tornado threat is very low, it is not zero.

However, we do note there is a large expanse of showers and storms across the Northern Gulf of Mexico and these could possibly be impeding our threat of strong storms during the overnight period as the flow from the Gulf of Mexico is blocked. Of course we are watching everything closely, but this ongoing activity could very much benefit us in Central Alabama. We are still going to forecast rain and storms this evening and overnight. What activity we see develop should be pushing out of the area during the late morning hours tomorrow and we should see a break in the action for most of Sunday afternoon and into the evening hours.

As we look at the latest day 2 convective outlook just issued from the SPC, it shows the entire state of Alabama is included in the “slight” risk for severe weather on Sunday. This is for what could potentially develop late Sunday and lasting into the pre-dawn hours Monday. This second round will be the one that we will have to watch very carefully as this is when the best dynamics will be approaching the area with the upper trough over the southern Plains. While it will be slowly weakening, the air will be more unstable, shear values and lapse rates suggest that some of the storms could produce damaging winds, large hail, and an isolated tornado or two will be possible.

We are continuing to monitor the situation carefully, and we are going to urge everyone to stay weather aware the next 48 hours, especially since the main threat for storms appears to be during the overnight hours; make sure you have ways to get and receive warnings. Always prepare for the worst and hope for the best, and expect surprises when it comes to thunderstorms in Alabama.

Weekend Weather Update

ABC 33/40 Weather Blog - Sat, 04/18/2015 - 08:20

This is a busy weekend for many with spring sports in full swing, and the two “A-Day” football games ahead at Tuscaloosa and Auburn.

The good news is that there is no rain on radar as of 8:00 this morning, and most of the morning should be rain-free. No doubt a few showers will begin to form this afternoon, but the good news is that it looks like the most widespread rain will hold off until tonight. This is model output from the high resolution HRRR model, valid at 3pm today…

So yes, take the rain gear to Bryant-Denny Stadium and Jordan-Hare Stadium, but there is a real chance both games will be played with few showers. Temperatures will be in the 70s this afternoon.

TOMORROW: Much of Alabama is in the standard “slight risk” of severe weather tomorrow…

There will be two main windows for strong storms… the first window will come from around 2 a.m. until 8 a.m. tomorrow; this will be more of a heavy rain event with limited instability, but a storm with hail and strong gusty winds can’t be ruled out. And, while the tornado threat is low, it is not zero.

There should be a lull in the action Sunday afternoon… then the second chance comes tomorrow night into the pre-dawn hours Monday… from about 10:00 p.m. tomorrow until 4:00 a.m. Monday. This is when the core dynamic support from the ejecting upper trough comes into play. While it will be slowly weakening, the air will be more unstable, and projected shear profiles and lapse rates hint that some of the storms could produce strong, perhaps damaging winds, and an isolated tornado will be possible.

Stay tuned to the blog for updates…

More Storms Later Today and Sunday

ABC 33/40 Weather Blog - Sat, 04/18/2015 - 07:35

To make the blog more user friendly for those using phones and tablets, we are now embedding the Weather Xtreme video at the top of individual posts. You can also subscribe to the Weather Xtreme video on iTunes by clicking here.

Looking for a brief break in the rain and storms for the morning and early afternoon before another round of rain and storms comes our way this afternoon and tonight. Clouds will keep temperatures from changing much but we should see highs push into the lower 70s. Severe weather is expected ahead of the closed low primarily from Texas to Nebraska later today.

The closed low over Colorado will open up and move eastward on Sunday bringing more storms. The overall pattern is conducive to a severe weather threat for Sunday with the greatest risk just to the west of Alabama, but all of Alabama is in the standard slight risk for severe storms with isolated tornadoes possible. The overall situation is somewhat messy with a highly saturated environment and the ongoing precipitation which could disrupt the overall severe weather potential for Central Alabama. Best CAPE values will be to our west and these values diminish into Sunday evening. However, better to err on the side of caution and be prepared for possible severe storms.

The severe weather risk slides east on Monday as we finally dry out with the carving out of a trough over the eastern half of the country. Tuesday and Wednesday look dry and very nice but chances for showers reenter the picture on Thursday as another cold front moves by.

Ridging aloft should bring a dry Friday to Central Alabama, but the pattern remains active with another trough coming out of the Rockies on Saturday that promises the potential for more rain and storms Saturday and possibly into Sunday.

At the beach, look for wet weather. A flash flood watch is in effect until Sunday for a large portion of the Gulf Coast from Pensacola westward to Galveston, TX. Not much sun for beach goers with rain likely through the weekend. Highs will be in the upper 70s today and Sunday. The weather at the beach should dry out for Tuesday and Wednesday.

The weather pattern remains active out into week 2 or voodoo country. The GFS is painting a large ridge which promises some much warmer weather for the start to May.

Occasional Showers/Storms Through Sunday

ABC 33/40 Weather Blog - Fri, 04/17/2015 - 15:53

To make the blog more user friendly for those using phones and tablets, we are now embedding the Weather Xtreme video at the top of individual posts. You can also subscribe to the Weather Xtreme video on iTunes by clicking here.

RADAR CHECK: Rain has ended for now across much of Central and West Alabama, but the rain continues over the eastern counties at mid-afternoon. We are even starting to see a few breaks in the overcast across West Alabama for a change…

Rain will end across East Alabama in coming hours, and the weather tonight will be relatively quiet, with only isolated showers. Temperatures are generally in the 60s this afternoon, well below average for mid-April in Alabama.

TOMORROW: It continues to look like the best chance of rain will come tomorrow afternoon into tomorrow night. We can’t rule out a few morning showers, but they should be widely spaced. Severe weather is not expected, and tomorrow’s high will be in the mid 70s.

SPRING FOOTBALL: While a passing shower is certainly possible, there is a decent chance much of the A-Day game at Auburn (1:00p CT kickoff at Jordan-Hare Stadium) will be dry tomorrow. For the Crimson Tide A-Day in Tuscaloosa, rain will likely begin at some point during the game, with the higher percentages coming during the second half. Afternoon temperatures will be in the 70s.

TOMORROW NIGHT/SUNDAY: As the upper trough lifts out of the western U.S., dynamic support for thunderstorms will increase. The Storm Prediction Center has most of Alabama in the standard “slight” risk of severe weather Sunday.

Strong storms are certainly possible early Sunday morning with a low level jet of almost 50 knots setting up across the state, but the instability values are pretty low (CAPE values below 750 j/kg). Perhaps there will be another window for severe storms late Sunday afternoon and Sunday night as the surface front approaches, but the higher wind fields have moved on to the northeast by then. If we do have severe storms Sunday, seems like the primary threat will come from hail and strong gusty winds, although the tornado risk is not zero.

Confidence in the specific timing of convection Sunday is fairly low; models have struggled with this pattern all week. But, one way or another showers and storms are likely Sunday with a high in the 70s.

NEXT WEEK: A few stray showers are possible Monday, especially during the morning hours, then we will enjoy beautiful weather Tuesday and Wednesday, with a good supply of sunshine both days, lower humidity, and cooler nights. Showers return later in the week Thursday and Friday, but for now the severe weather threat seems low. See the Weather Xtreme video for maps, graphics, and more details.

Occasional Showers/Thunderstorms

ABC 33/40 Weather Blog - Fri, 04/17/2015 - 06:34

SOGGY PATTERN CONTINUES: At daybreak rain is falling across parts of Central and South Alabama, and that rain is moving northward. Temperatures are in the 57-61 degree range in most places… it is cooler over East Alabama in the wake of the wedge front that moved in from the east yesterday.

It won’t rain all day today, and rain amounts will be lighter than yesterday for most, but no doubt it will rain at times with a cloudy sky. The high today will be in the 60s over the eastern half of the state, with 70s for West Alabama. Some thunder is possible, but there is no risk of severe weather for the northern counties.

WEEKEND FORECAST: Computer models are clearly struggling with the small scale details of this wet pattern; they have been all over the board making it a challenge to call the specific start/stop times of the rain over the weekend.

The latest batch of guidance for tomorrow is more encouraging for those of you trying to do something outdoors. Clearly, a shower is possible at any time, but it won’t rain all day, and the organized mass of rain and storms could hold off until late in the day and tomorrow night.

Seems the most widespread rain over the weekend will come tomorrow night into Sunday… interesting to note that the guys at SPC have put much of our state in the standard “slight” risk of severe weather Sunday.

With the big upper trough lifting out from the western U.S., dynamic support will increase for stronger storms, but for now it seems like surface based instability will be pretty limited, and shear values are not high at all. Some of the storms in Alabama Sunday could produce hail and strong, gusty winds; we will keep a close eye on parameters to see if anything changes. Seems like the overall tornado threat is low Sunday, but not zero. The high Sunday will be in the 75-80 degree range.

SPRING FOOTBALL: Annual “A Day” games are set tomorrow in Tuscaloosa (2:00p CT kickoff at Bryant-Denny Stadium) and Auburn (1:00p CT kickoff at Jordan-Hare Stadium). The news is a little better this morning with guidance holding off the most widespread rain until late in the day. A decent chance the game at Auburn will be played with generally dry conditions, although a passing shower is certainly possible. The chance of rain at Tuscaloosa will be higher, but I don’t think it rains for the entire game. One way or another I would take the rain gear at both stadiums. Temperatures will be in the low to mid 70s tomorrow afternoon.

NEXT WEEK: A few stray showers are possible Monday as the upper trough passes overhead, but we will finally enjoy two dry, sunny days Tuesday and Wednesday with lower humidity and cooler nights. Moisture returns late in the week with showers and storms possible late Thursday and Friday; the latest GFS runs suggest severe potential will be low, but it is too early to call. See the Weather Xtreme video for maps, graphics, and more details.

AT THE BEACH: Mostly cloudy conditions continue from Panama City to Gulf Shores through Sunday with occasional showers and thunderstorms, just a small risk of a shower Monday, followed by mostly sunny weather Tuesday and Wednesday of next week. Highs will stay in the 70s… and sea water temperatures are mostly in the low to mid 70s.

Unsettled April Weather Continues

ABC 33/40 Weather Blog - Thu, 04/16/2015 - 15:44

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.

WET DAY: Showers and storms returned to North and Central Alabama today, aided by a wedge front that pushed into Alabama from the east. Some flooding issues have been reported in a few spots; the image below was taken along Alabama 119 in Shelby County between US 280 and US 31 this afternoon (photo from @sparker2374)

Flooding has also been reported in parts of downtown Birmingham.

Radar continues to show rain and storms over much of North/Central Alabama…

As expected, it is much cooler over East Alabama with many places dropping into the cool 50s this afternoon.

TOMORROW: Don’t think it will be as wet as today. The wedge front dissipates, and showers become more widely scattered; a decent part of the day should be dry with a high in the 70s. The sun might even peek out at times.

THE ALABAMA WEEKEND: More rain. The high resolution NAM shows rain moving into West Alabama at midday Saturday, becoming widespread during the afternoon and into Saturday night. Sunday will be wet at times as well with occasional showers and thunderstorms. With a large scale upper trough approaching, we will need to monitor weather conditions for severe weather potential, but for now it looks like instability values will be pretty marginal, and the overall risk looks rather low. Rain amounts of 1-2 inches are likely over the weekend, and some flooding issues can’t be totally ruled out (like today). Highs over the weekend will be in the 70s.

A-DAY GAMES: Unfortunately it looks like rain will be likely for the Alabama spring game Saturday afternoon (2:00p CT kickoff) at Bryant-Denny Stadium in Tuscaloosa. Auburn’s game (1:00 CT kickoff) at Jordan-Hare Stadium will begin rain-free, but it turns wet by the second half. Temperatures will be in the low to mid 70s at both venues. Take the rain gear.

NEXT WEEK: We will continue to mention the chance of a few stray showers Monday, but drier air finally returns Tuesday and Wednesday with a good supply of sunshine both days along with lower humidity values. Temperatures should drop into the 40s early Wednesday. Then, later in the week, showers and storms will return. See the Weather Xtreme video for maps, graphics, and more details.

GULF COAST WEATHER: More clouds than sun each day through the weekend from Panama City over to Gulf Shores, with occasional showers and thunderstorms. A flash flood watch remains in effect for Dauphin Island, Gulf Shores, and Pensacola Beach. Highs will be in the 70s, and the sea water temperature this afternoon at the Dauphin Island Sea Lab is 73 degrees.

Rain and Storms Continue to Develop

ABC 33/40 Weather Blog - Thu, 04/16/2015 - 14:23

Click image to enlarge.

Heavy rain continues to develop in the I-20 corridor at this hour, with moderate to heavy rain all the way from the Pell City area westward into Jefferson and Shelby Counties they through Tuscaloosa and on into Pickens and Sumter Counties.

The heaviest accumulations according to radar estimates are over:

…southwestern Winston County
…Central Fayette County
…Central Tuscaloosa County around the City of Tuscaloosa and Holt
…over northeastern Tuscaloosa County into Southwestern Jefferson County

Some areas have picked up between 2-3 inches of rainfall.

An areal flood warning is in effect for southern Cullman County.

There is a good bit of embedded thunder involved as well, but the storms are not strong.

Rain and storms will continue to develop thanks to a backdoor cold front that has pushed into the area and uplift over the boundary of a moist southwesterly flow aloft as well as a passing upper level wind max that is helping increase upward motion.

Flooding Concerns Increasing

ABC 33/40 Weather Blog - Thu, 04/16/2015 - 11:01

Rain and thunderstorms have increased this morning over the southwestern half of the area, generally west of I-65 and south of US-280.

Rainfall has been especially heavy over the northern half of the City of Tuscaloosa over the past hour or so, with radar estimates indicating well over two inches of rain this morning. The NWS Birmingham has issued a flood advisory for much of Tuscaloosa County.

Click image to enlarge

The heaviest activity now extends from southwestern Cullman across Walker, western Jefferson, Tuscaloosa, western Bibb, Pickens and Greene Counties.

Recent rains have set the stage for grounds to become quickly saturated and heavy rainfall will be running off. There will be minor flooding in urban areas and quick rises on small streams. If prolonged heavy rains fall, more serious flooding is possible.

Click image to enlarge

The rain and storms are coming from a two pronged attack this morning. At the surface, we find a back door cold front at the leading edge of an easterly wedge nosing in from Georgia. This front is acting as a focusing mechanism for convection. Above the surface, winds are out of the southwest, providing a stream of moisture from the Gulf of Mexico that is riding up and over the wedge, providing for efficient precipitation making. Throw in an approaching wind max at the jetstream level that will provide additional lift as we go through the afternoon and we have the makings of a major rainy day for many.

Instability values to the west or ahead of the front are low to moderate, hence there is a good bit of lightning and thunder. Fortunately however, there is very low shear and not much chance for the storms to be severe. There will be loud booming thunder though in ddition to the threat for heavy rainfall and flooding.
