Forecasters still see an unseasonably warm weekend ahead, but they say it could end with thunderstorms.
Christmas week, they say, will be cool and rather quiet across the Carolinas.
A weak cold front crossed the region late Tuesday, bringing slightly cooler air to the area for Wednesday.
Then a warmup is predicted to get under way, as winds turn out of the southwest.
Highs on Thursday are forecast for the upper 50s, and then into the lower 60s Friday.
Even milder conditions are predicted for Saturday and Sunday, with upper 60s Saturday and lower 70s Sunday. Skies are expected to be mostly cloudy both days, but there will be breaks of sunshine.
By later Sunday, forecasters expect a cold front to be approaching the region. Showers are predicted to break out ahead of the front, and meteorologists say there will be enough instability in the atmosphere for thunderstorms to develop.
At this point, it appears as if the stormy weather wouldnt arrive until late afternoon or evening, perhaps after the Carolina Panthers big game against the New Orleans Saints. But some shower activity is possible during the game.
Severe weather is certainly possible Sunday afternoon and evening, said Doug Outlaw, of the National Weather Service office in Greer, S.C.
Showers are expected to linger into Monday, with highs reaching about 60 degrees.
Then clearing is forecast for Christmas Eve, with below-average temperatures. Highs are forecast for the upper 40s.
It appears as if the cool temperatures will last into late week, Outlaw said.
