It looks like the snow should fall after the morning commute and move out before the evening commute.
The storm will be fast-moving but potent with a snowfall rate of 1 inch per hour possible for a few hours. During this window of intense snowfall rates, the visibility will drop to near zero and road conditions will become difficult to potentially dangerous. The heaviest snow will fall between 11 a.m. to 1 p.m.
The Pa. suburbs, Lehigh Valley and Berks County will likely see 2 to 5 inches of snow with the highest amounts in areas that receive the most intense snowfall bands.
Philadelphia may be the dividing line where the northwest end of the county, including Mount Airy, Chestnut Hill, Manayunk and Roxborough, get a few inches. Down near Penn’s Landing, South Philly and Center City, however, there will likely be a coating to 2 inches of snow.
The storm is expected to transition to rain in Philadelphia and points south and east in the afternoon.
“This is not going to be an all snow event,” First Alert Weather meteorologist Bill Henley said Monday morning.
South Jersey and most of Delaware, south of Wilmington, will see mostly — if not all — rain.
The storm should move out around 4 p.m.
Temps then warm into the mid-40s Tuesday and even the 50s in many neighborhoods later in the week.
