South Carolina wakes under a gray veil as dense fog hugs roads across the Upstate. Headlights blur on damp pavement, and visibility drops below a quarter mile in spots around Greenville and Spartanburg.
Early conditions remain quiet but tricky. Temperatures sit in the mid-40s, with humidity near saturation. Fog lingers through the morning commute, especially along I-85, I-385, and secondary roads near valleys and rivers. Drivers should slow down and allow extra following distance.
As the day wears on, fog lifts and sunshine breaks through. Afternoon warmth surges, pushing highs into the mid-70s. It feels more like early fall than winter, a pattern holding across much of the Southeast. For now, travel improves and skies stay mostly dry.
Attention quickly turns to Sunday. Clouds increase, and a 30 percent chance of rain develops by late morning. While rainfall looks light, timing matters for holiday travelers heading home. Wet roads and lower clouds may reduce visibility again, especially during the afternoon.
Sunday night stays mild, with lows in the lower 50s. Winds pick up slightly, hinting at the next shift. By Monday, another round of rain becomes possible before noon, followed by clearing skies late in the day.
Behind that system, colder air finally arrives. Overnight temperatures drop sharply, falling into the upper 20s by Monday night. Any lingering moisture could freeze, creating isolated slick spots early Tuesday morning. This is the first real signal of winter tightening its grip.
Tuesday turns bright but colder. Highs reach the mid-40s, with crisp air settling in. Clear nights follow, setting the stage for chilly mornings through midweek.
Looking ahead to New Year’s Eve and the start of 2026, dry weather dominates, but cold nights remain. Travelers should prepare for fog early, rain late Sunday, and a quick freeze early next week.
