Winter Weather in Northern Lancaster, South Carolina

A band of mostly sleet mixed with snow moved through the county around noon on the 10th and continued through the afternoon, although no accumulation was reported. Temperatures aloft warmed into the evening and any lingering precipitation transitioned to freezing rain. The Lancaster County EM reported most secondary roads in the county had patches of ice and a few slip and falls were reported.

A broad mid-level trough pushed across the eastern CONUS throughout January 10th. The associated surface low pressure and warm advection caused a brief band of heavy snow, sleet, and freezing rain to develop in the Central Savannah River Area and southern Midlands. As temperatures warmed aloft and cold air damming conditions strengthened at the surface, the freezing rain shifted northwards with portions of the central and northern Midlands receiving up to 0.25 ice overnight into January 11th.
