South Carolina starts the morning under clear skies and calm air, but the quiet won’t last. A crisp chill settles across the Upstate as colder air filters in, setting the stage for freezing nights and sharp temperature swings before the weekend.
A few light showers linger early today, then clouds gradually thin. Afternoon highs reach the low to mid-50s, but cooler air arrives quickly after sunset. Northwest winds usher in a colder, drier air mass tonight, sending temperatures tumbling into the mid-20s across Spartanburg and nearby communities.
By Thursday morning, frost becomes likely on cars, rooftops, and grassy areas. Sunshine returns during the day, but it does little to warm things up. Highs struggle to reach the upper 30s, keeping a winter feel firmly in place. Winds ease by evening, allowing temperatures to drop further Thursday night. Lows dip near 18 degrees, marking the coldest stretch so far this month.
Friday delivers bright sunshine and dry weather, yet the cold lingers. Afternoon highs climb into the mid-40s, still well below seasonal norms. Another chilly night follows, with lows near freezing. Residents should protect sensitive plants, pets, and exposed pipes through Friday morning.
The weekend brings some relief. Saturday warms into the low 50s under mostly sunny skies, making it the most comfortable day of the period. Saturday night turns cold again, though not as extreme. Sunday stays sunny but cooler, with highs near 40 and a crisp breeze.
Looking ahead to the Jan 19–23 window, NOAA outlooks point to near-normal precipitation and lingering cool conditions across the Southeast. Winter isn’t finished yet, even if snow stays out of the picture.
