A long-duration, multi-faceted winter storm hit northwestern Pennsylvania just before Christmas 2022 with extreme cold, strong winds, accumulating snow and extensive blowing and drifting of the snow that fell. An Arctic cold front swept east across northwestern Pennsylvania during the early morning hours of December 23rd. Low pressure along this front tracked over Lake Erie early in the morning on December 23rd and rapidly intensified through the day while slowly lifting northeast across Ontario. With the frontal passage rain changed to snow with temperatures dropping from the upper 30s and lower 40s to sub-zero in about 8 hours. The snow was generally light to moderate, but a brief period of heavier snow with rates of around one inch per hour lifted through during the morning hours December 23rd. The period of snow and rapidly falling temperatures led to a flash freeze and icy conditions on area roadways. While the falling snow became lighter through the afternoon hours of December 23rd, winds began increasing during the morning and gusted over 40 MPH through the day. Peak gusts of up to 55 MPH were measured near the Lake Erie shoreline. Peak gusts across the rest of northwestern Pennsylvania were generally 40-50 MPH. Wind gusts very gradually subsided into December 24th, though gusts didn���t drop below 30mph until that evening. This led to a prolonged period of widespread blowing and drifting snow beginning during the morning December 23rd and continuing through the afternoon and evening, with some patchy blowing and drifting snow continuing overnight and all the way through Christmas Eve. In parts of northwestern Pennsylvania the blowing and drifting snow was extensive enough to lead to blizzard conditions on December 23rd. This storm caused a number of impacts across the area. The greatest impact was to travel due to the flash freeze and extensive blowing and drifting snow, to go along with low visibility. Numerous minor accidents, slide-offs and disabled vehicles were reported throughout the area on December 23rd and 24th. Wind chills dipped to -25 to -40 across all of northwestern Pennsylvania on December 23rd. A number of burst pipes were reported across northwestern Pennsylvania due to this cold, with temperatures remaining in the single digits until Christmas morning. Erie International Airport recorded 3.0��� of snow with this storm, with amounts as high as 8.0��� measured by a trained spotter in Greenfield Township.
