A rare late-season winter weather pattern may bring snow or freezing rain to parts of South Carolina during St. Patrick’s Day week (March 15-21, 2026), per the NOAA Climate Prediction Center’s 8-14 day outlook.
Forecast Setup
Colder Canadian air will push unusually far south along a longwave boundary from Maine through Georgia and northern Florida, favoring below-average temperatures in the Southeast and Mid-Atlantic alongside above-normal precipitation in the eastern U.S. Upstate areas like Greenville-Spartanburg and Asheville-border regions face the highest risk for frozen precipitation if moisture timings align.
Regional Impacts
Columbia and Rock Hill could see rain mixing with or briefly turning to sleet/freezing rain; Interstates 85, 26, and 77 warrant close monitoring for icy bridges. The setup overlaps daylight saving time start and spring’s onset (March 20), with details sharpening soon—potentially triggering alerts if systems develop.
