Charlotte, North Carolina – St. Patrick’s Day week across North Carolina could bring a rare late-season reminder of winter as colder air sliding south from Canada raises the possibility of snow just days before the official start of spring.
According to the NOAA Climate Prediction Center’s 8–14 day outlook, the period from March 15 through March 21 favors above-normal precipitation across much of the eastern United States, while temperatures trend below seasonal averages across the East Coast and parts of the Southeast. The setup develops as a broad cold boundary stretches from Maine through the Great Lakes and south toward Georgia and northern Florida, allowing colder Canadian air to spill deeper into the region.
That pattern could place Charlotte, Raleigh, Greensboro, and Asheville in a corridor where incoming storm systems interact with colder air, increasing the chance for late-season snow or rain transitioning to snow, especially across higher elevations of western North Carolina and the Blue Ridge Mountains.
Drivers along major routes including Interstate 40, Interstate 85, and Interstate 77 should monitor conditions if storms begin developing during the period. In the mountains, even light snow can quickly reduce visibility and create slick travel on higher elevation roadways.
The timing stands out because daylight saving time begins this weekend, yet winterlike conditions may linger across parts of the Southeast even as the first day of spring arrives later that week.
Forecasters expect additional updates in the coming days as the mid-March pattern becomes clearer, and advisories could follow if storm systems align with the colder air mass across the region.
