Snow beginning overnight could make driving hazardous throughout the morning Tuesday morning in the Philadelphia region, according to the National Weather Service.

Accumulations of two to four inches are possible north and west of the city, including in outlying parts of Chester, Montgomery and Bucks Counties.

The city, Delaware County and southern and central Chester County, should see an inch or two before rain mixes in or takes over in the afternoon.

Most of South Jersey and Northern Delaware should get less than an inch of snow.

Throughout the area, temperatures are expected to dip into the low to mid 20s overnight, before rising into the mid 30s by midday, so the morning commute could present icy conditions.

Snow could resume in Tuesday evening, but little more than a dusting is expected.

Not that snow is certain. The probability of precipitation Tuesday is put at about 70 percent, according to the National Weather Service.
