MONTGOMERY, Ala. (WSFA) - One of our hottest September days in the historical record has mercifully come to a close. We reached 103 degrees in Montgomery; that’s our hottest day since August 22, 2007, and the hottest September temperature since 1925. This is a living testimony to the way that a dry ground can really crank up the heat - when the ground has little moisture in it, more of the sun’s energy goes into the air. So, dry patterns are often very hot patterns, and this one is absolutely that.
Expect more brutal heat Wednesday; afternoon temperatures will again rise into the upper 90s and lower 100s across central and south Alabama.
But, thankfully, some slightly cooler air arrives from Georgia Thursday and will last through the weekend. Afternoon highs will drop into the upper 80s and lower 90s, and humidity levels will plummet, too.
It will feel nice, but the lower humidity will mean no widespread rain anytime soon. In fact, our two long-range computer models are in lock-step agreement that the next seven days will offer little to no rain for Alabama. We need it very badly.
In the tropics, things are busy. Tropical Storm Imelda made landfall along the southeast Texas coast; it will weaken but cause heavy rain and some flooding issues for parts of Texas and southwest Louisiana. Hurricane Humberto will curve out over the open Atlantic. And, back in the central Atlantic, Tropical Depression Ten and another potential system behind it bear close watch.
