Not bad today, tomorrow, then storms on Thursday: Southern MS/AL/LA Weather Forecast – 4/25/23

REMINDER: Check your settings on the app! Starting this week, based on your feedback, I’m going to be sending out a ‘morning ping’ regarding the updated forecast. If you want to opt-out of that, I’ve made that possible.

Some other ‘housekeeping’ notes. I’m re-working some of the maps and the Ag Forecast so those will not be in the daily email this week. But they will be back next week (I hope) with some added features. The forecasts may be a bit less robust this week, too, as I’m dealing with some personal / family things that are taking a lot of my attention outside of work. Apologies. But I’m not great at handling death. Especially those close to me.

Okay, on to the forecast….

I’m just about ready to put a fork in our Spring Tornado Season. While, sure a brief or weak tornado will still be possible with the next few systems that push through, the threat for the nasty big brothers like we saw in March is quickly coming to an end (unless something changes, drastically, within the model guidance).

The forecast does feature a few chances for rain and an outside shot for technical severe weather, though, in the coming days. But the main concerns will be brief heavy rain, lightning, gusty wind and small hail.

It looks like there’s a broad upper-level longwave trough hanging over much of the US today, with a low pressure system centered over the Great Lakes and another one sliding southeastward from Idaho toward New Mexico. Closer to home, there’s a subtle shortwave trough that’s causing some weak precipitation to develop over southern Missouri to northern Louisiana. The chances for anything measurable at the surface should remain farther north, with only a few brief sprinkles expected farther south into our forecast area. Rain chances will increase again late tonight into Wednesday morning as a more substantial low pressure system approaches from the west.

Midweek, there’ll be some zonal flow across the Gulf Coast, which means another chance for some rain on Wednesday. Depending on your location, you may end up with a brief downpour or a few sprinkles.

On Thursday, a shortwave trough will move in from NE Texas and bring widespread precipitation to our area. With some pretty decent values ahead of the system, early model guidance shows the potential for an environment favorable for isolated severe storms, with our main threats being damaging winds and hail up to quarter size. Highs look to push into the low 80s.

Friday through Tuesday, the previous trough will be exiting our region, although some showers may still linger. Weather should be mainly quiet through midday before a long wave trough developing over the Central Plains makes its way eastward. There’s limited potential for severe weather, but we’ll continue to monitor this system since it’s still a little less than a week away. Highs will be in the low to mid 70s for the weekend, with lows in the low to mid 50s.
