Columbia, South Carolina – Forecast confidence is increasing that winter weather could impact central South Carolina this weekend, though key details about timing and precipitation type remain uncertain.
According to the National Weather Service in Columbia, strong high pressure is expected to push cold air back into the region Saturday and Sunday, creating conditions favorable for winter precipitation. Forecasters report moderate confidence that a winter storm could affect portions of the forecast area, with the potential for moderate impacts depending on how the system evolves.
Probability graphics released by NWS Columbia show 30% to 50% odds of moderate winter storm impacts across parts of central South Carolina, including the Columbia area. Impacts could range from minor travel slowdowns to more disruptive conditions if snow, sleet, or freezing rain develops.
Officials stress that several important questions remain unresolved, including the exact timing of the storm, dominant precipitation type, and placement of the heaviest winter weather. Small shifts in storm track or temperature profiles could significantly change outcomes across short distances.
If wintry precipitation occurs, roadway conditions could deteriorate quickly, particularly during overnight and early morning hours. Drivers should be alert on Interstate 20, Interstate 26, Interstate 77, and major surface roads, where bridges and overpasses are most susceptible to icing.
The National Weather Service urges residents to avoid focusing on specific snow or ice amounts at this stage. Instead, officials recommend reviewing winter preparedness plans, monitoring forecast updates, and being ready for extended cold conditions during and after the weekend system.
Commuters, students, and weekend travelers in the Columbia area should plan for possible delays if winter weather coincides with peak travel periods Saturday night or Sunday.
Additional updates are expected as forecast confidence improves later this week.
