Rest of the work week: Record warmth expected Wednesday, then a front cools us off

/ March 10, 2026 at 11:08 PM

Another very warm day is on tap for Wednesday on the heels of the warmest day thus far in 2026. Wednesday’s forecast high of 87°, if it verifies, would break the daily record high for March 11 of 85° set in 2015. We’ll have plenty of sunshine for a good bit of the day, though cloud cover will tick up in the evening ahead of a cold front that will begin to restore a little order to a spring preview that’s gotten a bit out of hand.

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.
