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.
Generally quiet weather featuring plenty of sunshine and seasonable temperatures will bring us into Memorial Day Weekend as high pressure builds in at the surface for a couple days. Friday will start in the low-to-mid-60s and warm to the mid-80s in the afternoon with low humidity. It’ll still be a bit breezy, but not to the extent as we saw on Thursday.
A reprieve from the early-season stretch of 90° temperatures commences Thursday in the wake of a cold front. We’ll start the day noticeably cooler and drier than previous days, with lows bottoming out in the mid-60s as opposed to the low 70s. Highs will still run a little warmer than normal, but upper 80s will still represent cooler highs, especially on the heels of highs in the low 90s the past few days. Despite the warmer-than-normal temperatures, the lower dewpoints in the mid-50s will send relative humidity values down to around 30% or so during the day, so at least any sweat will have a chance to do its thing to cool you off.
The main weather story for Friday and the weekend will be the unusual midsummer-like heat, especially Friday and Saturday. We may break a record high on Friday — the record high is 94° set in 1941 — as temperatures head into the mid-90s under partly cloudy to mostly sunny skies. Heat indices will peak around 100° or so — not into heat advisory territory but still on the high side for mid-May.
Partly cloudy skies continue into Saturday, though a stalling front could pop a stray storm or two especially further north. Otherwise, expect another quiet and very warm day, with highs in the mid-90s once again expected after a low-70s start. The front meanders around the area on Sunday, keeping partly cloudy skies in the forecast with a stray storm not out of the question. Temperatures should run a touch “cooler” — and by “cooler” I mean around 90° as opposed to 95°.
The 90s stick around well into next week before the next front approaches by mid-week with the next mentionable shower and thunderstorm chances.
Wednesday was the warmest day thus far of 2025, with a high of 89° recorded at the airport. This distinction will be short-lived as high pressure continues to build in on Thursday, sending us to what should be our first 90° readings of the year in the afternoon. Mostly sunny skies are expected to prevail, so be sure to apply sunscreen if you are headed outside for a little pre-summer preview.
After a reasonably quiet Friday, shower and thunderstorm chances return to the forecast for the weekend, bringing with it a decent shot at some much-needed rain but also the risk for a strong storm or two on Saturday.
May Day will be a partly cloudy affair across the Lowcountry as Atlantic high pressure continues to exert influence over our weather. We’ll start near 60° away from the locally warmer coastline, warming to the mid-80s in the afternoon. It’ll be a bit breezy especially as the seabreeze gets by in the early afternoon, but otherwise no major concerns are expected.
A few more storms will be possible Thursday as the lingering stalled front hangs around a bit longer. This, combined with the seabreeze, keeps a slight chance for storms in the metro in play for a good bit of the day, though the rain chance should diminish as the seabreeze pushes further inland. Temperatures will still be on the warm side of normal, but cloud cover, storms, and onshore flow should keep highs suppressed to the low 80s.
Not much to write home about in the weather department as we head into Friday and Easter weekend as temperatures warm into the 80s and precipitation remains at bay for at least a few more days as high pressure continues to be the dominant weather feature.
Friday starts much warmer than Thursday did, with lows in the mid-to-upper 50s to start the day warming to around 80° in the afternoon under mostly sunny skies. We turn a few degrees warmer on Saturday before the temperature curve levels out a little bit on Easter Sunday as we start to see high pressure begin to slip away a bit ahead of a front. This will help cloud cover tick up across the area, though we will still have more than ample sunshine. Enjoy!
