Greenville, SC – Confidence is increasing that a winter weather system could affect North and South Carolina this weekend, bringing the potential for snow and freezing rain across a wide portion of the region, according to the National Weather Service in Greenville-Spartanburg.
The agency said forecast guidance increasingly favors winter precipitation beginning late Friday and continuing into early Sunday, though details on snowfall amounts, ice accumulation, and exact timing remain uncertain due to the system being three to five days out. Probabilistic outlooks show up to a 90% chance of at least minor winter weather impacts across parts of the Carolinas.
The highest risk corridor currently stretches along Interstate 85, Interstate 26, and Interstate 77, including areas from the Upstate through the central Piedmont and into the foothills. Snow and freezing rain could create slick road conditions, especially overnight, potentially affecting weekend travel and early February commuting.
According to the National Weather Service, periods of freezing rain raise concerns for ice buildup on trees and power lines, which can increase the likelihood of scattered outages. Rapid freezing and thawing may also contribute to ice jams on creeks and rivers, creating a risk of localized flooding in low-lying or flood-prone areas.
Residents are encouraged to monitor small waterways, clear drainage areas where safe, and prepare for the possibility of rising water levels. Officials also note that overnight ice, wind, and falling limbs may create noise disturbances, potentially disrupting sleep in some neighborhoods.
The National Weather Service emphasized that forecast confidence will improve as the event approaches and urged residents to check updated forecasts throughout the week.
This potential winter event may be particularly impactful for students, young workers, and weekend travelers moving along major interstate corridors as February begins.
