South Carolina’s Upstate starts the morning under quiet skies, but the air feels heavy with change. Clouds thicken, temperatures hover near freezing early, and a high-impact winter setup is taking shape just beyond the horizon.
According to the National Weather Service in Greenville-Spartanburg, hazardous weather is not expected today or tonight. That window is closing. Confidence is increasing that a major winter storm will affect northeast Georgia, western North Carolina, and Upstate South Carolina beginning late this week and intensifying through the weekend. Hazardous travel and power outages are increasingly likely.
Today stays dry with increasing clouds and highs near 51. Roads remain clear for now, giving residents time to prepare. Tonight turns mostly cloudy with lows near 34, cold enough for patchy frost in sheltered areas.
Thursday brings a brief milder push. Highs climb into the mid-50s, but rain chances increase late in the day. Moisture builds Thursday night, and the atmosphere begins to cool from the ground up.
Friday marks the transition. Rain becomes more likely, with highs near 50. By evening, colder air presses in. Rain may mix with snow as temperatures drop into the mid-20s. Wet pavement could freeze quickly after sunset.
Saturday looks increasingly dangerous. Snow and sleet may begin early, then transition to a wintry mix through the afternoon. Highs stay near 31. Ice accumulation becomes a concern, especially on bridges, secondary roads, and elevated surfaces. Saturday night appears more severe, with freezing rain, sleet, and snow continuing as temperatures fall into the teens.
Sunday stays locked in winter. Wintry mix lingers with highs near 28, keeping travel difficult. Conditions may improve slowly later in the day, but lingering ice remains possible.
Looking ahead, the 6–10 day outlook favors below-normal temperatures across the Southeast, with cold nights lingering into early next week.
