Low pressure over southern Louisiana and high pressure over the Carolinas are driving our weather forecast for the next several days. Both features will put the squeeze on this area, forcing in more Gulf of Mexico moisture (humidity), and hotter temperatures for the end of the week. the counterclockwise flow of the low, and the clockwise flow of the high will keep winds out of the south-southeast for the next several days.

Tuesday, there’s a decent chance for a few thunderstorms across the area. The rain chances are slightly better the further west and south you go from Tuscaloosa. Wednesday, there could be an isolated storm or two, rain chances are slim that day. The low will finally diminish and the moisture will dissipate as well. Thursday and Friday look to be dry, and very hot! Highs will be in the upper-90s both days with the heat index easily in the 105 to 110, or better, range both afternoons.

A weak cold front advances towards the area from the northwest on Saturday and Sunday. This will bring us an increased chance for showers and thunderstorms both days. The extra cloud cover and rainfall will keep temperatures in the lower-90s.
