The heat continues, with chances for rain most days this week: Southern MS/AL/LA Weather Forecast – 5/15/23

You know, there’s nothing quite like temperatures in the 90s in the middle of May. That said, while those 90-degree temperatures may be sizzling, we’re gonna have a little reprieve with those upper 60s dewpoints instead of the sticky 70s. Overnight, on most nights this week, we’re not gonna cool off too much either. We’re looking at lows in the upper 60s and low 70s.

But suffice to say it will be warm and muggy.

Surface high pressure is still gonna be doing its thing, so we won’t be seeing much rain or storms today compared to what we’ve had in the past few days. But hey, as we move into summer, we can still expect some of those afternoon showers and thunderstorms to pop up, thanks to the diurnally driven activity.

According to our showerter-range hi-res guidance, any chance of precipitation is gonna hold off until the early evening, and it’ll mainly be south of I-20 and near I-59 and to the east. Once the sun starts to go down, though, those rain and storm chances will start to fizzle out. Now, there might be some patchy fog hanging around the Pine Belt area this morning, but nothing too thick and dense to worry about.

Then, as we move through the rest of the week, the pattern starts to change a bit. Tomorrow, as the ridging starts to break down a bit, we may actually see some storms on Tuesday with the possibility of turning marginally severe – especially south of I-20. We’re talking about vertical totals around 27 and SBCAPE around 3000 j/kg. High PWAT values also means a chance we’ll see some locally heavy downpours too.

As we move into Wednesday, a cold front is gonna saunter its way southward. It won’t fully clear the area until Wednesday night – and you guessed it, that means more thunderstorms are in the mix. Severe weather here isn’t as likely, though.

Come Thursday, things should start to dry out a bit thanks to some drier air moving in behind the front, but hold on to your umbrellas because that moisture is gonna rebound on Friday and Saturday.

A surface high pressure system over the Gulf is gonna kick in some return flow, and by Saturday afternoon, we’re expecting another cold front to swing through. That means rain and storms are back on the table, especially with sufficient moisture and heating in play.
