LOOK AHEAD: Heat advisory through 7 p.m.; storms also expected

(WAFF) -

A heat advisory will be in effect for:  Madison, Morgan, Limestone, Cullman, Lawrence, Lauderdale, Colbert, and Franklin Counties from 12 p.m. until 7 p.m. on Tuesday. Heat index values could be as high as 105. Be sure to drink plenty of water and take frequent breaks to cool off if your plans take you outdoors.

While it’s hot, there is also a disturbance that is expected to track into the area from Tennessee Tuesday afternoon. This will interact with the hot and unstable air to produce clusters of strong to severe thunderstorms Tuesday afternoon and evening. Strong to severe thunderstorms are expected to develop along an old thunderstorm boundary during the peak heating of the day on Tuesday. These storms will develop in southern Tennessee and form a line as they track to the southeast.

Within this line of thunderstorms, it will be possible for some of the storms to produce significant lightning, torrential rain and damaging wind gusts in excess of 60 mph. These storms could create some issues for the commute home from work.  Winds in excess of 55 mph can down trees and power lines. The exact timing and strength of these storms has yet to be determined.  Look for some adjustments as they develop Tuesday afternoon and evening.

You can stay ahead of the storms by downloading the WAFF 48 Weather App. Text APPS to 44848 to get started.
