Event narrative

Snowfall totals ranged from 8 to 16 inches.

Wider weather episode

A strong cold front crossed Pennsylvania on Saturday afternoon the 19th. Much colder air poured into the Commonwealth behind this front, which was accompanied by several inches of snow, especially over the higher terrain areas. A slow-moving upper air low, which followed this front, slowly tracked across upstate New York into northern New England from Sunday the 20th to Tuesday the 22nd. A northwest flow of cold moist air around this upper level low combined with moisture from the Great Lakes leading to a prolonged period of heavy lake effect snow. The lake effect snow affected an unusually large part of central New York and made it down to extreme northeast Pennsylvania which typically doesn't see heavy lake effect snowfall. The heaviest lake effect snow affected extreme northeast Pennsylvania on Sunday afternoon and night where around a foot or more of snow.
