BIRMINGHAM, Ala. (WBRC) - The temperatures have greatly improved this evening and the sky will be clearing, with lows in the 70s. We could see some isolated fog development in the early morning; otherwise, the weather will remain nice and tranquil. I’d plan for more blistering heat on Tuesday. Temperatures will quickly rise into the upper 80s and low 90s, with heat index levels topping 103º. The sky will be mostly sunny, with only a stray shower or storm in the afternoon. If we do see a pop-up shower or storm Tuesday, the greatest chance would be southeast.

THE REST OF THE WORKWEEK AND WEEKEND: The next big thing weather-wise will be an increase in scattered storms on Wednesday. A broader southeast flow pattern, and an upper level low drifting west across Florida, will bring higher rain chances for Wednesday, Thursday, and Friday. I’d plan for the typical summer routine, with periods of hot and humid weather, followed by shower and storm development in the afternoon. This trend will continue through the weekend, so plan for the possibility of afternoon storm delays on Saturday and Sunday.

THE TROPICS: The remnants of the tropical system Henri continue to produce heavy rain over the New England States. We are also monitoring three tropical disturbances with a 40% chance of development in the Atlantic Basin. At this time, I’m not concerned about any impacts this week, but do stay tuned as we monitor the latest developments. We are closing in on the peak of the Atlantic Hurricane Season, which is around September 10.
