Columbia, South Carolina – A warmer-than-normal and wetter weather pattern is expected to settle across South Carolina heading into Valentine’s Day weekend, increasing the risk for periods of rain, fog, and travel slowdowns from Saturday through midweek. While no single severe storm is currently flagged, repeated rounds of moisture could create cumulative impacts across roads, rivers, and low-lying communities.
According to the National Weather Service Climate Prediction Center, South Carolina is favored for above-normal precipitation and above-normal temperatures during the February 14–18 period. This pattern supports mild daytime conditions while increasing confidence in rain-producing systems moving across the Southeast, especially east of the Appalachians.
In the Midlands, including Columbia, Sumter, and Orangeburg, periods of steady rain could lead to ponding on roadways and slower travel along I-26, I-20, and US-378. Reduced visibility from fog is also possible during overnight and early morning hours as warm, moist air moves over cooler ground.
Upstate areas such as Greenville, Spartanburg, and Anderson may see repeated rainfall that could stress drainage systems, particularly in urban and low-lying areas. While temperatures remain well above freezing, heavier rain rates could briefly overwhelm storm drains during peak showers.
Along the coast, including Charleston, Mount Pleasant, and Beaufort, rain is expected to be the dominant precipitation type. Tidal influences combined with persistent rainfall may increase the risk for minor coastal or poor drainage flooding, especially during high tide cycles.
Air travel through Columbia Metropolitan Airport and Charleston International Airport may experience occasional delays during periods of heavier rain or low ceilings, though widespread cancellations are not anticipated. Utility providers report no elevated concerns for wind or ice-related outages under this warmer setup.
This warmer, wetter pattern is expected to persist into midweek. Additional advisories may be issued as individual systems become clearer, and residents are urged to stay alert for updated alerts, particularly during overnight and early morning travel periods.
