Flash flooding possible, severe weather can’t be ruled out, Wednesday & Thursday: Southern MS/AL/LA Weather Forecast – 1/23/24

The rain overnight has ended and we are left with just drizzle and mixed cloud cover this morning. We will see off-and-on rain today. Nothing major anticipated, simply keep an umbrellas handy and get ready to use the windshield wipers.

Looking ahead to tomorrow and Thursday, we have a few things to keep tabs on. The Weather Prediction Center has outlined parts of the area with a Moderate Risk for flash flooding for tomorrow with up to 8″ of rain possible in some spots. Then a Slight Risk is in place for Thursday.

The WPC rainfall estimates show most of the heaviest rain will be to the west, but they also note (and I agree) that the specific location of the highest rainfall totals will be difficult to forecast for this event.

On top of the potential for flash flooding, we will also have the risk for some severe weather. I will say, it does look like this setup isn’t going to be quite as conducive for severe weather, but the potential isn’t zero, either.

The Storm Prediction Center has highlighted the area with a Marginal Risk for severe weather for both Wednesday and Thursday

It wouldn’t surprised me if they add a Slight Risk area for Wednesday across parts of southeastern Louisiana and southern Mississippi, but I that doesn’t mean the forecast will have changed much. It looks like the biggest concerns (outside of the flooding) will be for lightning, wind gusts up to 65mph, small hail and the chance for a few brief tornadoes.

Looking at some of the guidance, if tornadoes can develop they will have a fair bit of shear and helicity to work with, but won’t have much instability. So, I think the top-end for tornado strength would be EF-2. Those will be strong enough to do some damage to trees and homes, but aren’t the big brothers that clear out entire neighborhoods.

Beyond that, things start to clear out through the weekend and we get back to normal as we start next week.
