Excessive Heat And Severe Weather Today

By Jim Stefkovich, Meteorologist, Alabama Emergency Management Agency

CLANTON –Thursday, 7 am July 21, 2022

An Excessive Heat Warning has been issued for portions of western AL until 7 pm.  This includes the cities of Hamilton, Jasper, Tuscaloosa, and Demopolis.  Heat index values are expected to reach at least 110 this afternoon.  Much of the remainder of the state is under a Heat Advisory, with Heat index values from 105-109.

Dress in light colored, loose fitting clothing, drink plenty of water, do not leave kids or pets in vehicles, and avoid strenuous activity during the hottest part of the day.

Although models are still not in agreement with the development of today’s thunderstorms, the potential does exist for a line of storms and widespread wind damage (worst case scenario).  In this scenario, the line would develop in the northern sections of the state this afternoon and reach the coast after midnight.  

The other scenario is just for scattered storms to develop…still producing wind damage, but not as widespread.  A timing graphic is provided below but may need to be updated by early afternoon.  Remain alert for developing thunderstorms and go to a safe location in a sturdy building if you hear thunder.  Even if not severe, frequent lightning and very heavy rain will occur with today’s storms.

On Friday, redevelopment of thunderstorms and a few damaging wind gusts will be possible from late morning through early evening south of Hwy 80 – I-85.
