The south central US has been sweltering under a heat wave. There have been heat advisories out for a lot of the center of Mississippi and Louisiana. If that part of the world feels warm, you better believe it is roasting.
At 1155AM, CT, Hattiesburg was reporting a temperature of 93 degrees with clear skies. Much of the region was seeing clear skies, however there were a few isolated thunderstorms cropping up along the coast, near Bay St. Louis. Light sea breezes should keep the thundershowers well south of Hattiesburgh for the day, but a lower level trough in the Ozarks bears watching as a weather maker in southern Mississippi.
The Ozarks feature won’t be terribly well organized, and will be motivated by a weak cold front moving through the Ohio Valley, but because of the soupy atmosphere it will be moving through, destabilization will lead to widespread shower and thunderstorm activity around Tennesser but shifting to the south. Hattiesburg may see a rogue sea breeze storm on Saturday evening, but with the wave sinking south on Sunday, expect most of the afternoon to be fairly soggy, though severe weather isn’t really a threat.

I am slightly surprised by the well above average temperatures from the NWS and WeatherNation. They are already trending cooler than guidance. Here is the radar from midday, showing the storms I mentioned in the post.
