The National Weather Service (NWS) has upgraded the winter weather advisory to a winter storm warning for multiple counties in south-central Pennsylvania. A warning for 4 to 6 inches of snow has been put into effect for York, Lancaster, and Lebanon counties, as the new forecast was issued just before 11 p.m. on Monday.
The warning will continue to be in effect until noon on Tuesday, just like the advisory. Snowfall is expected to be at its heaviest during the overnight hours, gradually tapering off by midday on Tuesday. However, there may still be light snowfall lingering until around midday on Tuesday.
The National Weather Service (NWS) has issued a warning that roads are likely to be slippery, and the morning commute may be affected by hazardous conditions.
A winter weather advisory has been issued for Franklin, Perry, Dauphin, Cumberland, and Adams counties, predicting 3 to 5 inches of snowfall by Tuesday morning.
