GREENVILLE, S.C. – A blanket of thick fog greets early risers across Upstate South Carolina, muting headlights and slicking pavement before a sharp drop in temperatures sweeps in by Monday night. The shift from damp fall mornings to biting late-autumn cold could prove hazardous for drivers and gardeners alike, with a Freeze Watch already in effect through early Tuesday.
According to the National Weather Service in Greenville-Spartanburg, visibility will stay under a quarter mile in dense pockets through midmorning Sunday, especially near I-85 and U.S. 29. By Monday night, arctic air dives south, driving lows into the mid-20s and ending the growing season for good. Tender plants, sprinkler systems, and exposed pipes should be protected before temperatures tumble.
While skies stay mostly clear after the fog lifts, a brisk northwest wind Monday could add bite to the chill. Forecasters say the pattern signals the first strong cold snap of November, marking a firm step into early winter conditions across the Carolinas and north Georgia.
Drivers planning Veterans Day events or morning commutes Tuesday should prepare for frosty windshields and slower starts. Visibility and traction could briefly worsen where fog re-forms in river valleys and shaded hollows before sunrise.
Beyond midweek, temperatures gradually rebound toward the 60s under bright sun — ideal for raking leaves or early holiday decorating before another chill late next weekend. Longer-range models hint that colder air could return before Thanksgiving, potentially setting the stage for the season’s first southern winter tease.
