The stormy weather that started last night managed to linger into the start of our Labor Day. Although this rain held on a bit longer than we would have liked, it actually helped by lowering temperatures and instability through lunchtime. Now temperatures are on the rise and instability values are increasing. These conditions are sparking new shower and thunderstorm growth. Some storms over West Alabama have been quite strong and severe. A few strong to severe storms will be possible during the rest of the afternoon and evening. In fact, a tornado watch has been issued for some of our west and southwest counties (see graphic).
The remnant energy associated with Isaac will be merging with an upper level disturbance over Florida. This should cause the bulk of the wet weather to shift a bit eastward. Over the next couple of days we will have a partly to mostly cloudy sky, with highs in the upper 80s. Moisture levels will remain high so the heat index could top 95-degrees at times. This will be quite noticeable when the sun peaks through the clouds. Scattered thunderstorms will be possible, especially over eastern sections of the area.
We will have a better opportunity for some periods of sunshine on Thursday and Friday; however, a few afternoon storms can’t be ruled out. It’s going to feel hotter, with highs reaching the low 90-degree range.
The chance for rain is expected to go up on Saturday as a cold front approaches. Right now it looks as though the best chance of rain could come Saturday night as the front pushes into the state. Some strong thunderstorms will be possible. The wet weather should make a push southward early Sunday, with a taste of fall returning to Alabama. Less humid air is expected to arrive late Sunday and into Monday, with lows in the 50s in some of our northern communities.
Tropics: Leslie is the only named tropical system in the Atlantic basin right now. The latest forecast from the National Hurricane Center has the tropical cyclone tracking north through the week and developing into a hurricane. Bermuda is the only landmass in the threat zone and this system is not expected to threaten the United States.
