Warm, Sticky, and Stormy before a Big Cooldown Ensues – Weekly Outlook for South MS/LA/AL 4/2/25

If you look further up northwest around Arkansas to Missouri, you’ll notice a High (5/5!) risk for tornadoes and severe weather! There is a very optimal setup for tornadoes and historic flooding in the mid-South to the Mississippi/Ohio River valley. If you know anyone in that part of the country, contact them and make sure they’re safe because this will be a chaotic next several days for them.

If you haven’t noticed, it’s quite warm and humid outside. This is thanks to the inflow of moisture from the Gulf of Mexico due to the surface low clashing with an Atlantic high. This will lead to an optimal setup across the western part of the Deep South for severe weather closer to the weekend. We’ll see a slight chance of storms by Friday and a chance for severe weather Saturday evening into Sunday morning.

Tonight will be muggy as we’ll fall into the low 70s with some patchy fog possible into the morning hours. Thursday will be another warm and humid one with a mix of clouds and highs in the mid 80s. Winds will pull out of the south southeast around 10-15mph and wind gusts up to 30. Overnight, we’ll have a cloudy one with lows in the low 70s again. Friday will have a slight chance of storms moving in from the south especially in the afternoon. These look to be conditional, but still something to watch out for. We’ll reach the mid 80s and windy again.

Starting Saturday, the Storm Prediction center has put us under a slight risk for severe weather. While most of it will be to our northwest in the ArkLaMiss part of the Mississippi River valley, we’ll likely see some storms. Judging by the GFS and European model output, the main concern for us may be some cells that form ahead of the storm in the afternoon and evening. Both models differ on the timing of the main line. The line looks to weaken a bit as it stalls over us from the evening to overnight hours.

Our main concern for these storms would be heavy rain, localized flash flooding, straightline winds, and a possible tornado. I wouldn’t be surprised if we see a possible tornado in the leading cells as well as the main line, so please stay prepared going into Sunday morning. The rest of the line looks to hang around into the afternoon hours before the main cold front moves in. Afterwards, we’ll see temperatures begin to cool down. We’ll see highs in the low 70s and winds shift from the south to the northwest.

Surface analysis for Sunday from the Weather Prediction Center

The cooler weather is thanks in part to the trough that will bring the severe weather. This thing is fairly amplified, and an amplified ridge is soon to follow from the western US keeping the north winds blowing. While this won’t last forever, it’ll feel much better outside next week than it has for most of this week.

Afterwards, Monday will be quite cool with temperatures in the upper 40s in the morning with partly cloudy skies. Overnight, we’ll dip even further into the mid 40s. Tuesday will be a milder one with temperatures reaching the upper 60s to around 70 with north northwest winds and barely a cloud in the sky. Overnight, the temperature will reach the mid 40s again with winds shifting to the east. Wednesday will be a similar story with fair skies and temperatures reaching the low 70s with east winds.
