South Carolina – Gray clouds hang low over the Lowcountry this morning, and damp air clings to jackets along the harbor. Rain is already creeping inland, setting the stage for a wet stretch before a noticeable cold snap tightens its grip early next week.
According to the National Weather Service in Charleston, periods of rain continue today and tonight, with steadier showers developing at times. Gusty northeast winds may reach 20 to 25 mph, pushing rain sideways and lowering visibility on bridges and causeways. Roads across Charleston and surrounding coastal counties will turn slick quickly.
Rain chances ease somewhat during the day Sunday, though scattered showers remain possible, especially by Sunday night. Highs climb into the upper 50s, but cooler air steadily filters in behind the departing system. Wet pavement may linger into the evening commute.
By Monday, skies begin to clear and winds shift west, allowing colder air to settle in. Afternoon highs reach the mid-50s, but temperatures fall sharply after sunset. Overnight lows drop into the mid-20s away from the coast, raising concern for frost and pockets of freezing conditions.
Drivers should stay alert for changing road conditions, especially late Sunday night and early Monday. After rain clears, flash freezing could develop on shaded roads, bridges, and elevated surfaces. Give yourself extra time during early commutes and watch for slick spots.
Residents should secure outdoor plants, check pets, and protect exposed pipes ahead of the colder nights. Boaters should also monitor conditions, as breezy winds may create choppy waters near Charleston Harbor.
Midweek brings quieter but colder weather. Sunshine returns Tuesday and Wednesday, though mornings stay cold. Looking ahead, longer-range outlooks suggest below-normal temperatures hold across the Southeast while precipitation chances drop.
