According to weather officials, 1 to 2 inches of snow could fall north and west of Philadelphia but, generally, less than one inch should occur south and east.

During rush hour Wednesday morning, it should begin to rain, or snow) with precipitation increasing throughout the day. It's expected to be heaviest in early evening.

Overnight into Thursday, it could become all snow before gradually tapering off.
