Rest of the work week: Late-May weather in early March ramps up

/ March 3, 2026 at 10:04 PM

Generally quiet and rather warm weather continues for the rest of the work week. Wednesday morning will likely get off to a foggy start, with dense fog potentially reducing visibility to less than a quarter-mile at times. Use low beams and plenty of following distance in case you do encounter fog. Fog should erode by mid-morning, and we’ll head into the mid-70s under mostly sunny skies in the afternoon.

The week ahead: A cool start, but quite the warming trend to follow

/ March 1, 2026 at 10:08 PM

High pressure wedging down from the northeast overnight will set up a cool and mostly cloudy Monday across the Lowcountry — another dip on the temperature rollercoaster after an already up-and-down weekend. Temperatures start in the upper 40s with some fog possible (especially near the coast, where sea fog has been an issue), but the persistent northeast breeze and cloud cover courtesy of some moisture overrunning the wedge will keep temperatures pinned to the low 60s in the afternoon.

Friday & the weekend: Much-needed rain Friday, quieter this weekend

/ at 12:05 AM

Showers have arrived in the Lowcountry and will be hanging around through much of Friday into early Saturday as a cold front lumbers through the area. We certainly could use the rain as severe drought continues over the Lowcountry, and 1-1.5″ of rain should fall in most spots through Saturday morning.

Lows on Friday will run on the warm side of normal; expect generally mid-50s across the area, while highs peak near normal in the mid-60s.

The best chance for rain will arrive later in the day, and will stick with us into Friday. Temperatures Thursday start on a much more mild note — generally expect lows to fall to the low 50s in the morning, with highs peaking in the upper 60s in the afternoon.
