SCATTERED P.M. STORMS; HEAT ADVISORY AS 110° HEAT INDEX VALUES LIKELY… A Heat Advisory has been continued into today as a very hot, humid, brutal air mass remains in place across our region. A rare Excessive Heat Warning is in effect just to our north across much of north and central Alabama. Scattered showers and thunderstorms will pop up again this afternoon and this evening. Severe weather is not expected, but these small, localized storms will produce heavy rain, gusty winds, and cloud-to-ground lightning. More details are below…

EXCESSIVE HEAT WARNING FOR NORTH & CENTRAL ALABAMA… It’s been quite some time since the last Excessive Heat Warning was in effect for parts of Alabama. The thresholds have been met, in terms of the forecast heat & humidity today, for the local National Weather Service offices in Birmingham and Huntsville to trigger an Excessive Heat Warning for much of north and central Alabama. Brutal heat index values of 110-115° will be possible across the state and region this afternoon and this evening. If you’re working outside today, know the signs of heat exhaustion or heat stroke, two very serious conditions that can cause death if untreated. This is the Deep South in summer – I don’t have to tell you it’s going to be hot and humid. I do have to say, “Take it easy” if at all possible.

HEAT ADVISORY AGAIN TODAY FOR ALL LOCAL COUNTIES… The entirety of south Alabama and northwest Florida remain under a Heat Advisory today. High temperatures will be in the mid- to upper-90s. That is what appears on a thermometer. Once the dewpoint temperature is factored in, you get the heat index. Those values will again be between 110 and 115 degrees this afternoon, very similar to yesterday.

SCATTERED STORMS MORE LIKELY ON WEDNESDAY… Numerous showers and thunderstorms are likely on Wednesday, especially in the afternoon and evening hours. Some of the storms may be on the strong side, capable of producing gusty winds, small hail, and downpours of very heavy rain.

WEEKEND OUTLOOK… Scattered showers and thunderstorms are likely in the afternoon and evening hours this weekend. High temperatures will be in the low-90s with morning lows in the low-70s. Those temperatures will be far closer to our climatological norms for this time of year compared to the relentless heat and humidity of today.

TROPICAL UPDATE… Here’s the good headline: Tropical storm formation is not expected over the next 5 days in the Gulf of Mexico, Caribbean Sea, and Atlantic Ocean. There’s a little more to it than that as some of the weather models have indicated a low-end potential of some tropical mischief toward the beginning of next week, perhaps in the northern Gulf or perhaps off the Atlantic coast of Florida and Georgia. Environmental conditions don’t look particularly favorable for development at this time. I’ll keep closely monitoring model details. Nothing to worry about as of now!
