Showers Possible Late Today – Saturday 12:15 p.m.

Points north of Tuscaloosa and Pickens County are under a Slight Risk of severe weather today. The timeframe is from 3-10 pm. The mostly likely elements for us to see is hail and then some strong wind across parts of the area. The storms will remain isolated and not widespread. It will be much like our rain showers yesterday. The rain showers should be out of here by late tonight or early Sunday morning. If you’ll be heading out to the 2012 Tuscaloosa Regional Air Show, things are looking like they should be fairly nice for our Sunday with temperatures getting into the mid to upper 80s. Monday will be much of the same with sunshine and really warm temperatures before another front begins to move into the area late Monday and into Tuesday.

After looking at the latest ECMWF it appears that most of the medium/long range models are now in fair agreement with the evolution of the closed upper low. With that said there are still some timing and placement issues. The trend over the past couple days has been to slow the system down. Previous forecast packages have leaned more toward the GFS since it was the most consistent from run-to-run. Right now it looks like any activity associated with the cold front will hold off until Tuesday night. Still could see some scattered showers/storms on Tuesday, mainly due to daytime heating, as forcing will be an issue. The only lifting mechanism would be any mesoscale boundaries that may be present. There will still be the chance for some slight severe weather Tuesday mainly because of how unstable the airmass will be.

The cold front will approach the Mississippi River on Wednesday with showers and storms spreading into the area. The severe threat will continue as the airmass will remain unstable and due to the proximity of the front. Damaging winds and hail will continue to be the main threats. Rain chances will continue into Thursday as the boundary sags southward across the area. The GFS tries to bring another boundary across the area late in the week as the upper trough finally pushes off the Atlantic coast. There will be a slight chance of rain through Friday. Temperatures will remain well above normal through the entire forecast period but we could see a very slight decrease in temps in the middle of the week with highs in the mid 70s to low 80s.

Rain Ahead for the Weekend – Thursday 5:15 p.m.

A few thunderstorms have developed across northwest Alabama this afternoon in what appears to be a zone of weak low level convergence. The majority of the convection is near and downstream of an upper level disturbance currently along the upper Texas coast. The main challenge tonight is will the convection associated with the upper low get close enough to West Alabama overnight. Expect most of the convection across northwest Alabama to dissipate this evening after sunset. Showers and thunderstorm activity over northern Louisiana will continue to shift northeastward overnight with some convection likely reaching West Alabama by midnight. The best chance of rain will be on Friday as the upper level disturbance moves across the central Gulf Coast region. Bulk shear is fairly weak on Friday, so no organized severe weather threat and with the rain expected to develop early in the day cloud cover should also limit instability.

The system will move quickly off to the east Friday evening and most of the rain will shift into east Alabama with rain mostly gone by midnight Friday night. Upper flow becomes northwesterly by Saturday. A weak surface boundary will remain across the southeast counties and kept a small rain chances across this area. With upper ridge axis building over area by Sunday…thickness and numerical guidance support afternoon temperatures reaching the upper 80s in many areas.

Monday through Thursday

Model agreement over the timing of the system early next week continues to be the challenge in the long term forecast. 12z models continue to slow down the timing of the system.

A weak shortwave trough will eject out of northern Mexico into the southeast ahead of the main upper level trough on Monday. With plenty of moisture and instability in place across Central Alabama this weak shortwave trough will provide enough lift for some showers and thunderstorms across the forecast area on Monday. Some of these storms could be strong to severe. Due to models slowing down the speed of the main upper level trough, a better chance for strong to severe thunderstorms appear to be on Tuesday. On Tuesday a more robust upper level trough will move into the southeast states. Models show that the trough will have a slight negative tilt that will help steepen lapse rates. The main threats at this time appear to be large hail and damaging winds. Plenty of instability and moisture will be present for these storms to form. Some limiting factors will be relatively weak flow aloft with only 50-60 kts at 300 mb. However, enough divergence and diffluence aloft will be present for synoptic lift across Central Alabama. All current long range models are on board with this solution except for the ECMWF. The ECMWF solution has a more elongated trough with the bulk of the upper level support over the Upper Mississippi River Valley. Later forecast will continue to monitor the model trends and timing of the system early next week.

The cold front will move through Central Alabama by Wednesday morning. A few model solutions indicated some wrap around showers could linger into the day on Wednesday. Not enough confidence at this time to include lingering rain showers in the forecast on Wednesday. Cooler temperatures will move in behind the front with temperatures near normal late next week.

Warm Temperatures, Iso. Storms…Lower Weekend Rain Chances – Wednesday Afternoon Forecast Discussion – 5pm

Good Wednesday afternoon to you! It has been another nice and dry day, but temperatures are approaching hot levels this afternoon. Many spots have reached the lower to middle 80s under a partly cloudy sky. While moisture levels have been low over the past several days, you’ll notice an increase in humidity over the next couple of days as dewpoints rise.

A storm system passing north of Alabama will have no impacts locally due to a strong ridge across the south. The ridge is blocking the storm system from getting anywhere near Alabama. A moist south flow has developed ahead of the front and is allowing dewpoints to increase. Due to higher moisture content at surface, temperatures won’t be able to get as cool as recent nights. Look for lows to fall into the upper 50s to lower 60s through early next week.

The upper level disturbance that was expected to bring a good chance of scattered storms on Saturday has really fizzled out on our latest model data. That being the case, I’ve brought down the rain chances on Saturday to 30%. This means we’ll see more sun, warmer temperatures and drier conditions. There’s still a chance for isolated showers or storms, but most spots will stay dry and rain won’t last long at all. Look for highs to reach the lower 80s through the weekend. As the surface low and upper level disturbance moves well north east of Alabama, skies will become mostly sunny by Sunday, with highs in the middle 80s. Lows at night will remain in the upper 50s to lower 60s through next week.

There are big questions in the forecast for the Monday/Tuesday time frame. Right now model data is showing a large storm system developing and moving our way. This system is still questionable in our model data, so updates will likely be needed. There is a chance we may have to put severe wording in the forecast early next week.

The beach forecast is looking pretty nice along the Alabama Gulf Coast through the weekend. Look for a chance of scattered to isolated showers and storms, but rain chances will remain near or below 30%. Afternoon highs will reach the upper 70s to lower 80s, with lows in the 60s. This forecast is for the Gulf Shores and Destin Areas.
