Thursday: Brief reprieve from the chill

/ December 4, 2024 at 6:49 PM

A warmer day is on tap Thursday as we sit between one Arctic-sourced high pressure system moving away and another approaching the area that’ll chill us right back out for Friday. We start the day in the upper 30s to around 40°, which will run much warmer than we ran on Wednesday morning after lows in the 20s for much of the area (and even some upper teens in northern Berkeley County!). Temperatures will top out in the low 60s in the afternoon as gusty southwest to westerly winds (perhaps approaching 30 MPH at times) ahead of the next front keep us a little warmer. We should see the front come through with little fanfare other than an uptick in cloud cover, especially in the first part of the day.

Tuesday: Quite, quite cold

/ December 2, 2024 at 8:12 PM

A shot of cold air will drive temperatures back below freezing for Tuesday morning, with some upper 20s likely inland. The metro area should stay closer to the low 30s, but tomato, tomahto — it’s just gonna be cold. A decent northerly breeze will drive wind chills down into the mid-20s, too. Make sure you’ve got pets and plants in a safe and warm place overnight. Temperatures will struggle to the upper 40s at best in the afternoon despite plenty of sunshine, indicative of just how frigid of an airmass we’ve got to work with on Tuesday. Bundle up!

The week ahead: Below-normal temperatures continue, with a particularly cold stretch Tuesday and Wednesday

/ December 1, 2024 at 10:34 PM

Seemingly on cue for climatological winter, temperatures will remain below normal pretty much all week, with a couple reinforcing shots of cool air to keep us honest interspersed throughout. We stay mostly rain-free, with the possible exception of later Saturday night into Sunday as another front with a few showers looks to move by.
