Muggy air is back today as a warm front dissipates over us, and deep tropical moisture from Elsa moves up from the Gulf of Mexico. Scattered showers and thunderstorms have returned with the heating of the day. Some downpours are possible. High temperatures will be in the mid 80s. Tonight, unlike most other summer evenings, will be mostly cloudy with some lingering scattered showers. It will be muggy with lows in the upper 60s to lower 70s. Light Southeast winds at 3 to 5 mph.
A trough of low pressure aloft will move into the Southeast U.S. Wednesday at the same time Elsa is making landfall around the Big Bend of Florida. Normally, when a tropical system makes landfall east of Alabama, we would have dry air over us. But the trough will tap into the tropical moisture from Elsa and set off scattered showers and storms throughout the day. Some heavy rain will be possible. High temperatures will be in the lower 80s. Some rain will be lingering into Wednesday night with lows in the 70s.
On Thursday, Elsa will move northeast across the Carolinas, but the trough will remain over us. The deep tropical moisture will remain over Alabama, so expect more scattered to numerous showers and thunderstorms. Some heavy rain is still possible with any storm. High temperatures will be in the lower 80s.
The chance for rain will start to go down on Friday as Elsa is off the Northeast U.S. Coast and the trough pulls off to the east of Alabama. It will be partly cloudy, warmer, and still humid with scattered afternoon thunderstorms. High temperatures will be in the mid to upper 80s.
Weekend Outlook: The normal high humidity levels will stay over us all weekend. An area of low pressure will be located over the Great Lakes, and it will send some upper-level waves across the Southeast U.S. These waves will help set off some pop-up afternoon/evening showers and thunderstorms on Saturday and Sunday. Otherwise, we will be partly cloudy and hot with high temperatures in the upper 80s. The heat index will be around 95-100° each day.
