An Update To Central Alabama’s Weather Situation at 3:10 AM

| January 21, 2017 @ 3:18 am

For much of Central Alabama at this time, conditions are still rather quiet. Most locations are still dry at this point, but activity is picking up in the southwestern locations in the area. Currently, there are no warnings or our area, but several tornado and severe thunderstorm warnings are up in southern Mississippi. All of the storms are moving to the northeast at 40 MPH. Plenty of lightning, along with heavy rainfall can be expected within locations such as Selma, Marion, Uniontown and Demopolis shortly.

Latest from the Storm Prediction Center has a tornado watch lined up to be issued for much of the southern 2/3rds of the state, due to the risk for a few tornadoes, damaging winds, and large hail. We will keep you posted throughout the morning.

Be Ready For Strong to Severe Storms Early Saturday Morning

| January 20, 2017 @ 11:17 pm

Strong to severe thunderstorms are occurring over Louisiana tonight as a warm front lifts north out of the Gulf of Mexico ahead of an approaching upper level disturbance. The warm front will gain momentum overnight as the low level jet intensifies at about 5,000 feet and transports warm, moist low level air northeastward. A strong upper level jet max of over 125 knots (145 mph) will overspread the region, enhancing the storms.

Downstream, the airmass over southeastern Louisiana and southern Mississippi into southwestern Alabama will be destabilized by drier air aloft moving in from the west over the rich low level air coming off the Gulf of Mexico. Storms should continue to be severe through the overnight hours in these areas. Supercells with tornadoes will be possible.

A tornado watch has been issued for parts of Louisiana and southern Mississippi.

The mass of thunderstorms will enter West Central Alabama around 4-5 a.m., entering around Sumter County. They should reach Tuscaloosa by 5 a.m. and Birmingham by 6:30 a.m. They will get into East Alabama after 7 a.m.

Severe threat through early morning: orange=greatest threat, yellow=a few severe storms, green=isolated severe storms possible

The biggest threat of severe weather through 7 a.m. will come over Southwest Alabama, south of a line from Cuba to Thomaston to Beatrice to Atmore and Orange Beach. There is still a good chance of severe weather as far north as a line from Pickensville to Tuscaloosa to Brent to Prattville to Luverne to Navarre Beach. But storms could reach severe limits as far north as a line from Hamilton to Oneonta to Alexander City to Enterprise.

Through the morning hours, the severe threat will lift east northeast as well, with isolated storms as far north as US-278, scattered severe storms south of I-20 and the best chance for severe weather, including tornadoes, south of I-85.

Additional storms will develop Saturday night over Mississippi and move into western Alabama. There are still signs that the storms could have very large hail. This development is not as certain at this time, but could pose an enhanced severe weather threat.

Scott Martin will be providing continuous coverage starting at 3 a.m. on the blog as the storms approach Alabama. Stay tuned for the latest updates.

Friday Night Update

| January 20, 2017 @ 10:56 pm

A very active weekend is ahead for Alabama… with two rounds of potentially severe storms ahead.

A new tornado watch is bring issued for parts of Southeast Louisiana and South Mississippi through the early morning hours, and very active storms continue to develop quickly over Louisiana.

ROUND ONE: Severe storms will move into West and Southwest Alabama sometime in the 2-3 a.m. time frame… this is the forecast UH (updraft helicity) max through midday tomorrow, suggesting the highest tornado potential will be along and south of I-20…

In addition to the tornado threat, storms will be capable of producing hail and damaging winds. The main window for rain and storms will come from 3a CT until 9a CT; be sure you have a way of hearing severe weather warnings. A good app for this is WeatherRadio by WDT.

There will be a nice break from rain and storms from midday tomorrow through about midnight tomorrow night… the afternoon tomorrow should be pleasant with some sun at times and a high around 70 degrees.

ROUND TWO: We will have several waves of showers and storms from midnight tomorrow night through Sunday afternoon. With a generally unidirectional flow expected, the tornado risk is low; hail and gusty winds will be the main threat. It won’t rain all day Sunday, but a few passing showers and strong storms are likely.

Keep an eye on the blog for frequent updates through the weekend…

Complex Weekend Storm System

| January 20, 2017 @ 3:15 pm

QUIET AFTERNOON: We have a mix of sun and clouds across Alabama this afternoon with temperatures the low 70s; nothing showing up on radar. But, things get active over the weekend as a deep upper low forms west of the state, and unstable air moves northward.

Here is the latest thinking after viewing the new computer model data that arrived this morning…

ROUND ONE: The first opportunity for strong to severe storms will come early tomorrow morning, generally in the 3:00 a.m. to 10:00 a.m. time frame. High resolution model data suggests the best combination of instability, shear, and stronger wind fields will be over Central and South Alabama, generally south of I-20 (Tuscaloosa, Birmingham, Anniston and points south).

Storms early tomorrow morning over Central and South Alabama will be capable of producing large hail, damaging winds, and a few tornadoes. For now severe weather over North Alabama, north of I-20, looks unlikely early tomorrow morning.

TOMORROW AFTERNOON/EVENING: The main low level jet, about 5,000 feet off the ground, moves east of Alabama by the afternoon, and it sure looks like this could be a pretty quiet period with some sun breaking through the clouds along with temperatures approaching 70 degrees. But, the air will be rather unstable, and an isolated storm can’t be totally ruled out. But, generally speaking, we should be in a lull tomorrow afternoon and early tomorrow night with few, if any storms.

ROUND TWO: The next thunderstorm event comes Sunday with the upper low approaching. Storms could form as early as 2:00 a.m. Sunday, and the chance of storms will continue through the day, although by Sunday afternoon the stronger storms will shift down into areas south and east of Birmingham. Forecast wind fields are rather unidirectional, so for this round of storms it looks like the main threat will come from small hail and gusty thunderstorm winds… the tornado risk looks pretty low for now.

Rain amounts over the weekend should be in the 1-2 inch range, and flash flooding is not expected.

BOTTOM LINE: This is a pretty complex pattern, and understand there could be forecast changes as we get into the weekend, so keep up with the latest posts here on the blog. For now, the primary tornado threat seems to be early tomorrow morning over Central and South Alabama.

CALL TO ACTION: Be sure you have a way of hearing severe weather watches and warnings. At home, you need a properly programmed NOAA Weather Radio with a battery backup. On your phone, for warnings we recommend WeatherRadio by WDT. You can watch our live severe weather coverage on the free ABC 33/40 app. Here are the links…

Midday Forecast: Calm Today, Strong Storms Develop Late Tonight

| January 20, 2017 @ 11:01 am

We are seeing a mix of sun and clouds today and overall it is a calm day across the state. There are a few sprinkles showing up on the radar, but nothing too widespread.

Another very warm day and late this morning, temperatures are into the 60s, which is well-above average for this time of year. We are going to see highs this afternoon in the 70s.

In the latest day one convective outlook, the SPC has upgraded to an “enhanced risk” of severe storms across areas of South Mississippi and Louisiana, and maintains parts of West and Southwest Alabama in the standard “slight risk” of severe storms, with a “marginal” risk northeast to Birmingham.

The convective outlooks is valid through 6 AM CST tomorrow, so that is why we are seeing parts of the state highlighted in a risk for today. There is no threat of severe weather in Alabama today, this is for late tonight, after midnight, when we expect the first round of storms to begin to impact portions of Alabama.

This first initial round of storms will develop along the Gulf Coast of Louisiana and Mississippi in response to an upper-level jet streak that will provide the dynamic support for storms. These are expected to develop around midnight southwest of Alabama and rapidly head towards the northeast across the areas highlighted in the risk area.

For Alabama, the first chance of severe storms will come from roughly 3AM until 10AM tomorrow. During this time frame, these storms will certainly be capable of producing damaging winds, large hail, and tornadoes. It looks to be a rather stormy start to our Saturday especially across portions of South and Southwest Alabama.

I am just highlighting round one of the storms. There will be several rounds of storms through the weekend. We want to urge folks to remain weather aware this weekend, as this system has the potential to be a high impact event for the state. Make sure you have multiple reliable sources to receive severe weather notifications in the event a warning is issued for your location. With some of the severe weather occurring during the overnight hours, it extremely important that you are able to receive the alerts. As we head into tonight and through the weekend, be sure to check the blog frequently for the latest on the severe weather threat.

Severe Storms Possible This Weekend

| January 20, 2017 @ 6:23 am

ACTIVE PATTERN: A complex severe weather situation is setting up for Alabama over the weekend, but today will be fairly quiet. Morning clouds will give way to some afternoon sunshine, just a small risk of a shower, and afternoon temperatures reach the mid 70s, right around record levels for mid to late January in Alabama.

There will be three windows for severe storms across Alabama over the next 2 days. Let’s take them one at a time.

ROUND ONE: The first chance of severe storms will come from roughly 3:00 a.m. until 9:00 a.m. tomorrow as a deep upper trough gets closer with strong wind fields, deep shear, and unstable air. SPC has parts of West and Southwest Alabama in the standard “slight” risk of severe storms, with a “marginal” risk northeast to Birmingham. Understand this “Day One” outlook runs through 6:00 a.m. CT tomorrow, and this is for the overnight storms we expect late tonight, after midnight…

ROUND TWO: There should be a lull in storm activity across the state during the midday hours tomorrow, allowing temperatures to rise into the low 70s, with increasing instability values. A few scattered storms could form tomorrow afternoon and evening, generally in the 3 p.m. to 9 p.m. time frame. This is a much more conditional threat; some of the good high resolution models show no development at all. But, considering the thermodynamic fields, we sure can’t rule out a few scattered severe storms in this window. In their “Day Two” outlook, SPC has an “enhanced risk” up for parts of West Alabama, and the standard “slight” risk identified for the rest of the state. Keep in mind this outlook runs from 6:00 a.m. tomorrow through 6:00 a.m. Sunday…

ROUND THREE: The final window for severe storms will come from about 3:00 a.m. through 12:00 noon Sunday, when the main upper low moves in from the west. Then, by Sunday afternoon, the main severe weather risk shifts down into Southwest Alabama, where SPC has the standard “slight” risk up on the “Day Three” outlook…

So, bottom line is that there could be multiple rounds of strong to severe storms over the weekend, but there will also be some good breaks in the rain.

THREATS: During each window over the weekend, storms could produce large hail, damaging winds, and a few tornadoes.

RAIN: Additional rain amounts of 1-3 inches are likely; major flooding issues are not expected.

CALL TO ACTION: Be sure you have a way of hearing severe weather watches and warnings. At home, you need a properly programmed NOAA Weather Radio with a battery backup. On your phone, for warnings we recommend WeatherRadio by WDT. You can watch our live severe weather coverage on the free ABC 33/40 app. Here are the links…

NEXT WEEK: Monday will be cloudy, windy, and much cooler with some lingering light rain, mainly during the morning. The high will be in the 50-55 degree range. Even colder air arrives later in the week with highs dropping into the 40s. See the Weather Xtreme video for maps, graphics, and more details.

Rain Moving Out; Several Rounds of Severe Weather Possible Over the Weekend

| January 19, 2017 @ 9:12 pm

The line of thunderstorms is now into Georgia above Randolph County. South of there, they curve back to the east of Wedowee, Alexander City and Wetumpka.

The storms are at the vanguard of an area of moderate to occasionally heavy rain that is about 35 miles wide.

An areal flood advisory was just issued for Autauga and Almore Counties.

The rain has now ended in the Birmingham area, but to the northwest, showers continue across the northwestern part of the state. Everything is lifting to the northeast at about 30 mph.

The rain will be out of the area after midnight and lows will drop into the middle and upper 50s.

Current satellite/radar with isobars and temperatures.

Tomorrow will be a pretty nice day: partially sunny with mild temperatures in the middle 70s and a balmy southerly wind. The day should be dry.

An areas of showers and storms will overspread the state after midnight Friday night, affecting much of the area Saturday morning. Severe weather is a threat with this system, especially with a strengthening low level jet and strong winds aloft. The threat should be south of I-20, and more significant the further south that you go.

There could be additional development during the afternoon on Saturday, which could also be severe, but this is a little more doubtful because of the morning convection. But the environment will be set for severe storms through the later afternoon and into the overnight as we find ourselves in the warm sector of a developing low that will track near Memphis.

The storms will continue into Sunday morning. More storms may develop ahead of the eventual cold front on Sunday afternoon, with some threat for additional severe weather.

All modes of severe weather will be possible with this slow moving system. Please pay close attention to the latest updates and forecasts throughout the weekend, starting tomorrow.

Rain and Storms Pushing East

| January 19, 2017 @ 6:36 pm

A band of rain and thunderstorms continues pushing east across Central Alabama this evening.

At 635 p.mm. it extends from Fort Payne to Pell City to west of Talladega to west of Rockford and west of Prattsville this into Southwest Alabama.

The heaviest weather is over southern Talladea County extending into western Coosa County into Autauga County.

Further southwest, a severe thunderstorm warning is in effect for parts of Wilcox County.

So far, no warnings in the NWS Birmingham county warning area, which is great news. There is still a small chance of severe weather ahead of the main line of storms.

Here is the radar reflectivity on the left and rainfall that has fallen on the right.

Beneficial rains are falling. I have picked up 1.60 inches here in Vestavia. Only 1.08 inches of ran through 6 p.m. at the Birmingham Airport but it was continuing to rain.

There is an areal flood advisory, less serious than a flood warning, for parts of Chilton County where 1.5-2 inches of rain has fallen with more rain coming. Some minor flooding will occur there.

Rain is continuous back into Mississippi, back the back edge is coming over the border near Meridian.

Rain will end from the southwest over the next 3-4 hours. It should end in Birmingham by 11 p.m.

New forecast data indicates that between 1.5-2.5 inches of rain will fall across much of Central Alabama between now and Monday morning. Lesser amounts are expected along the Alabama/Mississippi border closer to 1-1.25 inches.

Severe weather is still a significant threat for the weekend. Stay tuned.
