First Flakes Fell
As temperatures dropped on Tuesday, many neighborhoods saw rain change over briefly to snow.
The first places to get snowflakes were the Lehigh Valley, Berks County and northern and western suburbs. Snow then moved into Philadelphia and points south and east in the late morning.
Snowflakes in many neighborhoods fell before the temperature dropped below freezing. The snowfall looked worse to the eye than the impact it had on people going about their routines.
The snow accumulation wasn't significant, however as much of it melted as it hit the warmer ground. Snow did, however, stick to colder surfaces like parked cars and grass in some places.
Snow had ceased in Philly by early afternoon. All the wet weather pushed out of the region before the afternoon and evening ride home.
