Weekend forecast: Another very cold start on Saturday; turning warmer Sunday

/ December 6, 2024 at 6:03 PM

We are off to another frigid start on Saturday. Many spots in the metro will dip into the low 20s, with upper teens expected further inland. A Cold Weather Advisory is in effect for inland Berkeley and Dorchester counties, with the expected window of coldest air between 3-9am. Temperatures will moderate throughout the day, and we should get back above 50° once again, with highs topping out about in the low to mid-50s under sunny skies.

Temperatures will take another plunge toward freezing on Sunday morning, though we can expect lows to generally run some 10-12° above where they were on Saturday morning. This will mean that some spots inland will likely dip back into the low 30s once again, but much of the metro should stay just above freezing, especially the closer to the coast you are. We’ll see a few more clouds as high pressure starts to move offshore, and the resulting return flow will allow highs to peak in the mid-60s — much closer to normal for this point in December and some 20° warmer than we felt on Friday!

The warming trend continues for the first part of the week as the next storm system works into the area, with rain chances starting Tuesday and peaking Wednesday. The end of next week looks to close out below normal once more, though not to the advisory-level cold we’ve had recently.

Enjoy the weekend and don’t forget to bundle up!

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.

We’ll add a little amplitude to the temperature rollercoaster as we get into the second half of the work week as one high pressure departs and another builds back in.
