A Wet Weekend with a Cooler Start to the Week – Weekend Outlook for South MS 4/20/24

Yesterday was quite hot and muggy with temperatures reaching the mid 80s and a some cumulus clouds in the sky and it made it almost look like summer was here! Well, we’re nearing it considering how soon it usually happens in the South, but we’ll soon get a few days of relief at the beginning of this coming week.

Surface analysis for today from the SPC

Looking at the surface analysis, we have a long low pressure system that is stalling over the coastal south. This will keep showers and thunderstorms riding the stationary front over the next 24 hours as it slowly moves further south towards the coast.

The early afternoon should be fairly clear for much of south Mississippi, but we’ll see a thin line of cells start to develop over the Pinebelt, mainly to the south as we get closer to the evening. The SPC does have us under a marginal risk for severe thunderstorms, and it looks like the storms developing this evening are the main reason. While these don’t look to be anything crazy, there is always a chance for hail, high winds, and flash flooding. This looks to be the main window for the severe weather as it will begin to wane after dark.

Overnight into Sunday, we’ll see a steady amount of rain coming in. If you’re getting ready for church or work in the morning, you’ll probably need an umbrella since this system doesn’t look to get outta here until around noon.

Right behind the system is a fresh breeze of cool, dry air. Temperatures will even out during the day and only reach the 60s as the cold front pulls in. Even at night we’ll see temperatures drop into the 40s for a couple of nights as the ridge builds over the south. Overall, the start of the week will be a nice fresh start.
