Mississippi Skies: Dangerous long-lasting excessive heat now likely for another few weeks

Published 8:25 pm Tuesday, August 1, 2023

At least one region of Mississippi now has a long-range forecast that includes excessive heat warnings and advisories for another two or three weeks without much of a break.

The National Weather Service office in New Orleans/Baton Rouge expects at least a 70 to 80 percent chance of above-normal highs at least through Aug. 11. Although excessive heat warnings in place already caution about safety for people and animals outdoors or without air conditioning, this NWS office cautioned days upon days of the dangerous heat can be even more dangerous because isn’t much of a chance for bodies to recover.

We’ll be mostly dry Wednesday, but heat extremes and high humidity could help an isolated shower or thunderstorm to develop in the afternoon. The best chance, although a very small chance, is in southern Mississippi Wednesday.
