Central Pennsylvania is preparing for its first significant winter storm of the season, as a fast-moving system is expected to bring widespread plowable snow to the region starting late Monday night and continuing through Tuesday. The incoming storm has prompted the National Weather Service (NWS) to issue a Winter Weather Advisory for several counties, with a Winter Storm Watch still in effect for others.
Forecasters anticipate a widespread snowfall event, with the heaviest snow expected during the Tuesday morning commute.
Timing: Snow is expected to begin in Central PA before sunrise, potentially as early as 3:00 AM Tuesday, and will be heavy at times through the morning. Precipitation is forecast to taper off by early to mid-afternoon.
Accumulations: Most of Central Pennsylvania can expect 2 to 5 inches of snow. The NWS indicates a “most likely” forecast of 4-5 inches for the northern two-thirds of the region. Higher elevations, particularly east toward the Poconos, could see greater totals.
Warmer/Southern Areas: There remains some uncertainty about the rain/snow line, especially near the Pennsylvania/Maryland border and the lower Susquehanna Valley. Southern-tier counties may see a mix of rain, sleet, and freezing rain, which could limit snow totals in those specific areas.
The timing of the storm is expected to severely impact the Tuesday morning commute. “Hazardous driving conditions will set up across the area… The hazardous conditions will impact the Tuesday morning commute,” cautioned a recent advisory.
Commuting: Travelers should prepare for slick and hazardous roads, especially on bridges and overpasses, and plan for extra travel time. Snowfall rates could locally approach 1 inch per hour, making conditions deteriorate rapidly.
Disruptions: With this expected to be the first significant, “plowable” snow of the season, schools are likely to face closures or move to virtual instruction. Residents are advised to check local school and business closure announcements.
Preparedness: Authorities are urging residents to gather winter gear, including shovels and salt, ahead of the storm’s arrival.
While the snow is expected to end Tuesday afternoon, cold temperatures will remain through the week, meaning residual travel impacts are possible, particularly on untreated surfaces.
