South Carolina feels almost springlike across Spartanburg this morning, with humid air and overcast skies hanging over downtown. Temperatures are already in the mid-60s and climbing toward 78 degrees by early afternoon.

According to the National Weather Service in Greenville-Spartanburg, a chance of showers continues through midmorning, followed by gradual clearing. West winds between 10 and 13 mph may gust up to 25 mph. Brief downpours could dampen stretches of I-85 and I-26, but widespread flooding is not expected.

Keep an umbrella nearby through late morning.

Clouds increase again tonight, with lows near 52 degrees and a 40 percent chance of showers after 2 a.m. Saturday turns wetter. Rain becomes likely, mainly before early afternoon, with highs near 64 degrees and light winds.

Another round of rain arrives Saturday night into early Sunday. By Sunday afternoon, skies begin to clear as highs settle near 54 degrees.

Then the cold arrives.

Sunday night temperatures drop sharply to around 28 degrees under mostly clear skies. Gusty winds may develop behind the cold front late Sunday into Monday, especially across higher terrain. Strong gusts could approach advisory levels in the mountains.

That sharp drop raises a flash-freeze concern where roads remain wet.

Monday stays sunny but colder, with highs near 43 degrees. Tuesday rebounds to near 50 under bright skies. By midweek, temperatures climb into the upper 50s, and longer-range trends favor above-normal warmth late next week, signaling early spring vibes returning to the Upstate.
