It's beginning to look a lot like winter.

The weekend not only brought the season's first snow, but the coldest temperatures since March.

Consider that a tuneup.

More snow could arrive tomorrow night, and lows could be in the 20s Thursday and Friday night.

Autumn's previous low of 31 was reached Nov. 7 and tied yesterday.

Even the highs will be low, with Friday and Saturday expected to top out in the high 30s.

Before last Saturday, only four fall days failed to reach 50 degrees. By nightfall tomorrow, that number should double.

Snow is likeliest, starting late tomorrow, to the north and west of the city, with Reading and Easton possibly getting a half-inch or more.

Rain is likely to be part of the mix in the city, the nearby suburbs and South Jersey. Rain could change over to snow late tomorrow night, then change back to rain overnight.

Wednesday - the warmest day of the week with a high near 50 - could also see rain.

No further precipitation is expected through Sunday night, when the Eagles visit the Meadowlands to take on the New York Giants.
