Pennsylvania – Snow bands developing off the Great Lakes could begin impacting western Pennsylvania roads within the next 24 hours, with several inches of accumulation possible through Thursday night.
According to the National Weather Service Climate Prediction Center, temperatures across the Northeast are expected to hold near seasonal levels from Sunday through Thursday, while precipitation probabilities trend above average. With cold air firmly in place, that pattern favors snow, especially across western and northern Pennsylvania.
Erie and surrounding communities along I-90 may see 3 to 5 inches of lake-effect snow, with locally higher totals if bands remain stationary. Visibility could drop below one mile at times, creating hazardous travel along I-79 and portions of U.S. Route 19. Pittsburgh may pick up lighter but steady accumulations, particularly during overnight hours when untreated bridges freeze quickly. Farther east, including State College and Scranton, snowfall amounts appear lower but periodic bursts could still coat I-80 and secondary roads.
PennDOT crews may treat elevated roadways overnight. Drivers should slow down, increase following distance and carry winter emergency supplies during longer trips.
Additional advisories are possible as snow bands shift through Thursday night.
