After a beautiful weekend, the pattern begins to shift back toward warmer and more humid conditions once more, bringing about the return of shower and thunderstorm chances later this week into the weekend.

The week ahead gets off to a hot, humid, and unsettled start, but by the end of the week, temperatures will be more befitting of — if not a few clicks below — what we’d expect from late September.

We tied a record high Sunday, and should at least threaten if not break the daily record again on Monday. From there, slightly cooler high pressure builds in from the northeast, bringing a little whiff of more seasonable air for mid-September.

A very warm climatological summer — perhaps a top-three warmest on record — comes to an end on Monday as we roll into September. It won’t feel like fall, though, as temperatures head back to the mid-90s as clouds and showers give way to sunnier skies.

The week ahead will certainly not run as hot as the past two weeks have been, but that comes at the cost of afternoon thunderstorms each day, with a risk for heavy, flooding rain increasing as we get toward the second half of the week.

We have a few more days to go in the most dangerous part of this heat wave before the pattern finally begins to dislodge, allowing temperatures to trend back toward — but remain above — normal for mid-August.

The main weather story this week will be the return of heat that will be reminiscent of what we experienced earlier in July, with another round of dangerous heat indices pushing 110-115° at times.

The first week of August looks unsettled with more rain on the way, especially in the first half of the week as low pressure aloft becomes cut off and stalls for a couple days.

After a very wet weekend that included flooding rains at Mt. Pleasant and Isle of Palms, we should see a bit of a downtrend in rain chances as some of the deeper moisture that’s been hanging around this weekend moves offshore and further into the Atlantic. The pesky cold front that’s been hanging around will start the day just to our south, lifting north during the afternoon, so between this and the seabreeze, it’s still possible for a few afternoon thunderstorms to fire. Temperatures will run in the mid-70s Monday morning, topping out in the low to mid-90s in the afternoon. Heat indices should run around 102-106°, highest near the coast.

The week ahead will continue to feature warm and muggy conditions, with an uptick in rain chances as we get over the hump toward the weekend.
