South Carolina — Headlights glow softly through lingering fog as the morning begins across the Upstate. Moist air clings to roadways, muting visibility and slowing early travel. Conditions feel calm, but changes are already unfolding.
Patchy fog hangs on through the morning hours, especially near low-lying roads and shaded neighborhoods. Visibility may dip at times, creating brief travel slowdowns. Drivers should allow extra space and use low beams until fog thins.
By late morning, fog lifts and skies brighten. Temperatures climb quickly, reaching the mid-60s this afternoon. A light southwest breeze develops, with occasional gusts near 20 mph. It will feel mild for early January 2026, more like March than winter.
Midweek turns even warmer. Sunshine dominates Wednesday as highs surge near 70 degrees. Outdoor plans benefit, but cooler nights continue, with lows dipping into the low 40s. To be fair, that temperature swing can still produce early-morning fog.
Thursday stays quiet and mild, though clouds begin to increase late. Meteorologists are now tracking a developing system that brings higher moisture levels back into the Carolinas. Rain chances rise late Thursday night and increase into Friday.
By Friday and Saturday, periods of rain become more likely. Wet pavement and reduced visibility could affect travel along I-85 and Highway 29, especially during busier daytime hours. No winter precipitation is expected, but slick roads remain a concern during cooler mornings.
Looking ahead, temperatures remain above average into the weekend before a cooler trend arrives late Sunday. Winter stays quiet for now, but rapid changes remain possible during the first full week of 2026.
