COLUMBIA, S.C. — We are expecting a significant drop in temperatures as much colder, drier air pushes into South Carolina this weekend and early next week. This weather shift will bring some of the coldest conditions since early this year, with lows dropping into the low to middle 20s early next week.
Near-Term Weather Outlook (Through Tonight)
Colder, drier air continues to settle into the region. Freeze warnings are in effect for areas still in the growing season. The warning is from 3 AM to 9 AM Saturday. This warning includes Aiken, Calhoun, Clarendon, Orangeburg, and Saluda counties. This marks a likely end to the growing season in those locations.
As an upper trough moves eastward today, arctic high pressure will spread across the middle of the country, driving much cooler air into the Southeast. Highs this afternoon are expected to peak in the mid-to-upper 50s under mainly sunny skies, about 20 degrees cooler than Thanksgiving Day.
By late afternoon, skies will clear, and dewpoints will drop into the 20s. This will set the stage for below-freezing temperatures across most of the region tonight, with lows ranging from the mid-20s in sheltered areas to around 30 degrees elsewhere.
Weekend Weather: Saturday Through Sunday Night
Temperatures will stay below normal all weekend. Subfreezing overnight lows are expected as high pressure strengthens over the area. Saturday will be chilly, with highs in the 50s and clear skies. Sunday may feel slightly warmer during the day but will still be cooler than normal. Overnight lows both nights will drop below freezing, so frosty mornings are likely.
Looking Ahead: Monday Through Thursday
Early next week, another area of high pressure will bring the coldest air of the season to the region. Lows on Monday and Tuesday nights could fall into the lower to mid-20s, prompting the potential for a cold weather advisory. Well-below-normal temperatures will dominate early in the week before slowly climbing back toward seasonal averages by midweek.
Tips to Stay Prepared
Protect sensitive plants by bringing them indoors or covering them. Make sure outdoor pets have a warm place to stay during the cold stretch. Wear layers to stay warm and have extra blankets on hand for chilly nights. It is also a good idea to check on neighbors, especially those who might need help staying warm.
