Weekend forecast: Turning warmer with a few more clouds

/ May 15, 2026 at 10:12 PM

We’ll turn warmer over the weekend as high pressure aloft and at the surface remain the main weather features. With high pressure moving offshore, winds out of the south and southeast will bring warmer and somewhat more humid air into the area. This will contribute to a little more in the way of cloud cover, but despite that cloud cover, highs still peak in the mid-80s. Clouds thicken in the mid and upper levels on Sunday, but that doesn’t stop temperatures from running in the upper 80s in the afternoon. Shouldn’t see any rainfall, though, as the better moisture and rain chances will be well, well inland. Not excellent for the ongoing extreme to exceptional drought across parts the Lowcountry.

Friday & the weekend: Plenty of sunshine, increasingly warm

/ May 14, 2026 at 9:26 PM

Generally quiet weather will continue for Friday and the weekend with high pressure in control. If you liked Thursday’s weather, we have more of that comfortable warmth in store for Friday. We’ll start the day a bit below normal — generally mid-50s — and warm to the low 80s in the afternoon.

Thursday: More sunshine, comfortable warmth

/ May 13, 2026 at 6:13 PM

A cold front will swing through early Thursday with high pressure to build in behind it. Temperatures will start in the low 60s, warming to the low-to-mid-80s in the afternoon with northwesterly winds around 10 MPH. The downslope flow will dry out the atmosphere pretty nicely, allowing for mostly sunny skies with maybe a few fair weather clouds. The drier air will make the 80s highs feel a little more comfortable, too. Overall, it’s a good day to try to get some sunshine in the midst of the daily grind.

Generally quiet weather will be the rule for the rest of the work week as dry high pressure builds in from the northwest, keeping temperatures near mid-May norms.

Tuesday: Mostly cloudy and a bit on the cool side for mid-May

/ May 11, 2026 at 9:48 PM

High pressure nudging in from the north will keep cloud cover in place and cool us off a bit for Tuesday after the third 90° day of the year on Monday. We’ll start the day in the upper 50s, warming to about the mid-70s given the expected cloud cover. A shower could get close to far southern Charleston County during the day, but most of us should stay rain-free.

The week ahead: Unsettled to start, but summer-ish this weekend

/ May 10, 2026 at 10:19 PM

I hope all of you out there who celebrated Mother’s Day today had a wonderful day. It ended up being a pretty good weekend weather-wise, with much of the moisture staying suppressed to the south. Monday, however, will bring more substantial rain chances as a cold front pushes south and eastward. We should stay quiet through the morning, though by early afternoon we should start to see showers and a few thunderstorms develop, first along the seabreeze and then becoming more widespread as the front moves by later in the day into the evening. There’s a risk for one or two thunderstorms to become severe, with damaging wind gusts the main concern, though widespread severe weather is not expected. We could see some brief periods of heavy rain, but with relatively quick storm motions expected, they won’t be hanging around long enough to cause any flooding issues. Temperatures will run on the warm side of normal for mid-May, with highs potentially reaching the upper 80s before thunderstorms kick in.

Weekend forecast: Turning unsettled again, but it won’t rain all the time

/ May 8, 2026 at 8:32 PM

Showers and a few thunderstorms return to the weather picture this weekend as disturbances aloft ripple across the area. The good news is that it won’t rain all the time and that whatever rain we will get will help with the ongoing severe drought.

Friday & the weekend: A quiet Friday, then turning unsettled again

/ May 7, 2026 at 10:05 PM

We’re back in the saddle here at @chswx HQ and looking at a quiet Friday before conditions turn unsettled once again this weekend as the front that’s helped to bring us today’s rain starts to wobble back northward.

The next seven days: A chilly and wet Saturday gives way to increasingly warm days; next front Thursday

/ May 1, 2026 at 6:54 PM

We’re taking a look at the next seven days tonight as I’ll be taking a bit of a break over the next few days. A more regular posting schedule resumes Friday!

A rain-cooled day is on tap for Saturday — not quite peak air show weather, that’s for sure — as we may challenge a record cool high temperature. The coolest high temperature on record for May 2 is 63°, set in 1978; the NWS forecast for the airport currently calls for highs to reach about 64°. It’s gonna be close! As mentioned, some much needed rain will be falling throughout the day, with some rumbles of thunder possible with some elevated instability. No severe weather is anticipated, though. It’ll be generally on and off through late afternoon before tapering off in the evening. Many of us should see an additional inch to inch and a half of rain before it’s over — quite a nice sight given the ongoing severe drought.

Friday & the weekend: Wet and cool start to May

/ April 30, 2026 at 11:38 PM

After completing what should go down as the second-driest April on record (only by virtue of measurable rainfall over the past two days), we will get May off to a more unsettled start with some much-needed rain followed by a cool but sunny Sunday. We will also need to keep an eye on tides for possible coastal flooding concerns into the weekend.
