(WAFF) - Dangerous heat covering most of the Tennessee Valley
A heat advisory is once again in effect for a good portion of the Tennessee Valley, including Madison, Morgan, Cullman, Limestone, Lawrence, Lauderdale, Colbert, and Franklin Counties. Heat indices here could get up to 110 degrees with actual highs topping out in the upper-90s. Stay hydrated if you plan on working outside, and be sure to take frequent breaks in the shade or air conditioning.
Isolated rain showers are ongoing this morning. It's warm and muggy with many starting out their day in the mid-70s. Morning clouds will thin, and we should still see a fair amount of sunshine today. Temperatures will warm quickly with midday readings already into the low-to-mid-90 with highs topping out in the upper-90s as scattered storms begin to pop up this afternoon.
A cold front will move into north Alabama Thursday but it should still be a hot day ahead of the front with highs into the mid-90s with the heat index around 100-105 degrees. Scattered storms should develop along the front, and some of them could be strong with locally heavy rain, frequent lightning, and gusty winds up to 45 mph. A few storms could become severe, both today and tomorrow, with damaging wind gusts of 60 mph.
