A cold front is poised to sweep through South Carolina, bringing an abrupt end to the recent spell of mild weather and ushering in much colder conditions. As reported by South Carolina Public Radio, residents should prepare for a significant drop in temperatures, with overnight lows plummeting to the mid-20s in Greenville and hovering near the freezing mark along the coast. This cold snap will mark the first freeze of 2026 for many regions, echoing the weather patterns experienced between Christmas and New Year's Day.
