A Cooler Week? Maybe? – Weekly Outlook for South MS/LA/AL 8/3/25

So if you’ve been looking on the news recently, many people in the northern parts of Mississippi and Alabama have been all over the cold front and sub 90s temperatures. Is it going to affect us as much? Eh, kinda. Is this a foray into fall? Nah, probably not. The good news is, though, it will bring the heat index down a bit so we’re not completely miserable like last week.

Starting off the week, we’re stuck between a stationary front and a frontal boundary. That might sound like the same thing, but the stationary front will keep flowing in more dry air and the boundary will keep the rain further east towards Alabama and Georgia. This will keep on for the next day or so as rain chances stay east until Tuesday. Overall, expect some drier conditions with a slight northerly wind and temperatures in the low 90s and heat indices in the mid to upper 90s.

Tuesday and Wednesday will increase our rain chances a bit as the frontal boundary dissolves and allows more sea breeze thunderstorms to move in from the coastline. This will be the continuing trend for the rest of the week with highs in the low 90s and heat indices reaching the mid 90s to around 100 especially further west towards the Mississippi River Delta. By Thursday, a surface high will move in on the west side of the Gulf and increase the heat risk further west.

Friday through the weekend will be hot but not especially humid as the stationary front begins to dissolve. The heat index will stay around the upper 90s to 100, but overall it’ll be a much less miserable weekend. Rain and thunderstorm chances stay the same as the latter part of the week with mostly pop-up and sea breeze thunderstorms to contend with. As the week after moves in, we’ll see a slightly warmer trend that looks to move heat indices into the low 100s and stay fairly steady. This is due to a building high pressure zone from the northeast Atlantic creeping into the mid-Atlantic states, and eventually the Deep South.
