Winter Weather — Southern Lycoming, Pennsylvania

2021-02-22 · Southern Lycoming, Pennsylvania

Event narrative

SNOW SQUALL. A snow squall on the leading edge of a mesoscale band of heavy snow briefly dropped visibility to under one quarter mile in and produced flash-freeze conditions in southern Lycoming County.

Wider weather episode

Low pressure passed over the Great Lakes and up the Saint Lawrence River valley from February 22 into February 23, 2021, pushing a warm front and cold front across central Pennsylvania. A narrow, north-south stripe of heavy snow (1-2 per hour) associated with the warm front passed over the Susquehanna Valley during the morning rush hour, and the heavy snowfall rates combined with the potential for a flash freeze prompted the issuance of snow squall warnings.
