The week ahead: Staying rather unsettled

/ June 8, 2025 at 8:12 PM

Warm, muggy, and unsettled weather will continue heading into this second week of June as a front stalls out nearby, which will help to instigate numerous showers and thunderstorms with the heating of the day each afternoon.

Weekend forecast: Warm and occasionally stormy

/ June 6, 2025 at 7:38 PM

Heat and humidity will continue to feature prominently in the weekend’s weather as we watch disturbances to our west potentially introduce a risk for strong to severe thunderstorms at times. If you have outdoor activities planned this weekend, keep a close eye on the weather.

Friday & the weekend: Turning hotter, severe risk increases

/ at 12:27 AM

The good news for Friday is that storm chances trend downward, with just some isolated storms on the seabreeze expected in the afternoon. We could stand to dry out a bit, especially after the deluge in Summerville on Thursday, and Friday gives some of us an opportunity to do exactly that. It’ll be very summerlike, though, with highs around 90° after a low 70s start, and low-70s dewpoints will make it feel more like the mid-to-upper 90s.

Thursday: More storms, especially in the afternoon

/ June 5, 2025 at 12:26 AM

Thunderstorms remain likely, especially in the afternoon, as low pressure lifts north and away from the area throughout the day. A warm and humid airmass remains in place, and this will get us off to a balmy start in the low 70s. Scattered to numerous showers and thunderstorms should redevelop by afternoon, keeping highs suppressed to the mid-80s. Rain could still be heavy at times, with spots potentially reaching another inch of rain or so before it’s over. Not everyone will see that kind of rain, though.

Breezy conditions remain possible especially at the coast and over the waters, so it’ll be another day where boating and beaching will be generally unadvisable. The good news, though, is that with the low pushing inland, the risk for any sort of tropical development — low as the risk was this entire time — has ended. (Take the wins where you get them.)

Rest of the work week: Turning soggy Wednesday and Thursday as a coastal low moves by

/ June 3, 2025 at 7:31 PM

A coastal low will bring numerous showers and thunderstorms, some with potentially heavy rain, to the Lowcountry starting late tonight and peaking Wednesday into Thursday.

Tuesday: One more quiet day, then the rain begins again

/ June 2, 2025 at 9:21 PM

We’ve got one more day of quiet weather in store for Tuesday before low pressure offshore begins to send moisture back our direction starting Wednesday. Temperatures Tuesday start in the mid-60s, and we’ll warm to the mid-to-upper 80s under generally partly cloudy skies as high pressure builds in briefly from the north.

The week ahead: Quiet start, but unsettled weather returns later in the week

/ June 1, 2025 at 8:18 PM

We will stay quiet heading into the first couple days of the work week, but low pressure moving into the area will help turn the weather more unsettled for the second half of the week and into the weekend.
