Winter Storm — Union, South Carolina

2022-01-16 · Union, South Carolina

Wider weather episode

Moisture overspread the South Carolina Piedmont late on the 15th as strengthening low pressure moved across the Deep South. Strong northeast winds supplied ample cold air for the precipitation to begin as light snow across much of the area, resulting in light snow accumulations of up to a couple of inches during the pre-dawn hours. Slight warming of the air aloft resulted in snow changing to sleet across much of this area by sunrise. By late morning, total snow and sleet accumulations of 2 to 5 inches were reported, with locations south of I-85 seeing more sleet. Further warming aloft resulted in precipitation briefly changing to freezing rain before tapering off by early afternoon, with light ice accretion reported on top of the sleet and snow. However, scattered snow showers redeveloped during the afternoon and evening, producing spotty additional light accumulations.
