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.

It’s that time again: Hurricane season starts today

Living at the coast is pretty amazing for the most part. We say “for the most part” because there is one key exception to the rule: Hurricane season, which resumes today and will run through November 30. Once again, we’ll be monitoring the tropics with vigilance throughout the summer and fall, watching for potential threats to the Carolina coastline that might require us to hide our cows and head west.

Weekend forecast: Nice respite for Saturday, a storm possible Sunday

/ May 30, 2025 at 8:45 PM

A welcome respite from the humidity and constant threat of storms arrives in the wake of a cold front on Saturday. It’ll be noticeably cooler in the morning, with lows bottoming out in the low 60s with the cooler and drier air setting into place. Temperatures warm nicely to the mid-80s in the afternoon, and humidity will be on the low side for the end of May, which is a nice cherry on top.

A stalling front and some energy aloft could stir up a few thunderstorms Sunday afternoon, but otherwise it should still be a decent day of weather outside of those storms as dewpoints mix down to the upper 50s in the afternoon. You’ll want to keep an eye out for popups as you embark on your outdoor activities, but many of us should be rain-free for much of the day.

Friday & the weekend: Much better this weekend after a Friday front

/ May 29, 2025 at 9:24 PM

A respite from the rain is coming just in time for the weekend (and it’ll be a beaut), but we’ve got one more day with storms — and the risk for a few severe storms, at that — coming up with a cold front on Friday.

Thursday: Afternoon storms return

/ May 28, 2025 at 8:32 PM

After a balmy start in the low 70s that could feature some patches of fog, temperatures will warm to near 90° in the afternoon before scattered to numerous showers and thunderstorms kick off courtesy of the seabreeze as well as some energy aloft. Heavy rain will be possible with these thunderstorms, and a few stronger storms with strong winds will be possible as well, with some of the high-res models pointing to clusters of storms developing and moving from southwest to northeast across the Lowcountry late in the day. Stay alert for rapidly changing conditions, particularly during the evening commute.

Rest of the work week: Active pattern continues

/ May 27, 2025 at 8:10 PM

The active pattern that’s kept things on the stormy side the past few days will continue until a front sweeps through the area late Friday, clearing things up a bit for the weekend. For now, though, we’re still going to be dodging scattered to numerous showers and thunderstorms each afternoon.

Rest of the work week: Staying stormy

/ May 26, 2025 at 9:46 PM

The weather will remain unsettled for the rest of this last work week of May with plenty of warm and humid air for various surface boundaries and mid-level impulses to stir things up, especially in the afternoons and evenings.

Memorial Day: Storms continue, especially late afternoon into the evening

/ May 25, 2025 at 11:58 PM

While we probably won’t get off to as stormy of a start as we did on Sunday, expect another round of showers and storms to kick off by afternoon on Memorial Day. We’ll start the day in the mid-to-upper 60s, warming to the mid-to-upper 80s in the afternoon before thunderstorms once again kick off with a stalled front in the vicinity. The risk for severe weather remains on the low side, but heavy rain and lightning will still be enough to disrupt outdoor plans at times. Storm motions will be toward the coast as well, so be especially alert for thunderstorms at the beaches. Remember, all thunderstorms are dangerous due to the lightning they produce. If you see lightning or hear thunder, you’re close enough to be struck, and should move inside.

We’ll also want to pay close attention to the flooding threat not only from training thunderstorms but also the evening high tide, which should peak between 7.1-7.3’ MLLW around 8:16 PM. If thunderstorms are in the area around that time (as some models seem to suggest), this could indicate a greater flooding threat for vulnerable locations in downtown Charleston. This will certainly be something to watch as the day progresses. Stay alert for possible flood advisories from the National Weather Service.
