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.

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.

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.

Expect less in the way of cloud cover on Tuesday as the front that helped focus some shower and thunderstorm activity across the area on Monday meanders north and high pressure builds in aloft with plenty of dry, sinking air to be found. We’ll stay on the toasty side of normal for mid-May, with lows in the low 70s warming to the low-to-mid-90s in the afternoon. Dewpoints aren’t terribly out of control, thankfully, so heat indices won’t be too much of a factor, only running about 2-3° or so above the air temperature. That said, it’s still quite warm for this point in the year — the normal high for May 20 is 84°.

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.

Much quieter weather is expected for Tuesday as a surface front moves by, shunting the plume of deep moisture that has absolutely soaked us for the past few days offshore and allowing the sun to break out. There’s still going to be some cloud cover, but we should get a good chance to dry out today.

There is going to be the risk for a few isolated storms to pop back up late today into tonight, but otherwise, it should be a good weather day with highs topping out in the low to mid-80s.

Shower and storm chances return Wednesday, but will be relatively short-lived as high pressure builds back in to close out the week, bringing us a sustained stretch of 90°+ highs and perhaps some even warmer heat indices as well.

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.

Another seasonably warm and mostly sunny day is on tap for Tuesday as high pressure remains in control. We’ll start the day on the cool side of normal once again, with lows in the mid-to-upper 50s expected away from the coastline. Then, temperatures warm to the low 80s in the afternoon with plenty of sunshine throughout. Don’t forget the SPF!

We will still need to monitor tides in the late evening as water levels should peak between 7-7.2’ mean lower low water in Charleston Harbor a little before 10:30 PM. Some minor salt water flooding will be possible an hour or two around the time of high tide as a result, and another coastal flood advisory appears probable. This should do it for this high tide cycle, though, as astronomical influences wane and winds turn more unfavorable starting Wednesday.

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.

We’ve got another warm and generally quiet day of weather inbound for Tuesday. Temperatures will, in fact, run a little warmer than they did on Monday despite some additional cloud cover as high pressure aloft begins to break down. Expect generally mid-80s in the metro after a mild start in the mid-60s — temperatures that are climatologically much more in line with early June than they are late April.

A stray shower can’t be totally ruled out as the seabreeze pushes inland, but otherwise, most of us should have one more rain-free day across the area.
