PHILADELPHIA (CBS) — Saturday felt like late April across the Delaware Valley as high temperatures surged into the 60s.  Astronomical Spring officially arrives this Thursday, but Winter wants to hang on.

A cold front moving through will allow another push of colder air to settle into the region for the rest of the weekend.  A southern storm system current developing will track into the mid-Atlantic late Sunday night bring another round of wintry weather.

Sunday will remain dry with partly sunny skies but a northerly breeze will keep high temperatures well below average of around 40 degrees.  A cold high pressure area over the Northeast will lock in the cold air.  Snow will begin to arrive late Sunday night and continue overnight through Monday morning.

Initially, temperatures should be above freezing allowing for the snow to melt, but overnight temperatures will drop into the 20s.  Expect snow-covered roads for the morning commute allowing for slow travel.  Any snow that does fall during the daytime on Monday will have a harder time sticking, due to the strong mid-March sun angle with temperatures holding in the 30s.  The snow will taper off by early afternoon with drier conditions for the afternoon commute.

Still, the big question is, how far north will the storm track?  Today’s trend has been for a track a bit farther to the south.  The track is critical for snow amounts since there will be a sharp cutoff right around the Delaware Valley.  This depends on where the strong high pressure area to our north sets up.  A last-minute change in track could mean getting no snow at all or 3 or more inches for some locations.

As of Saturday evening, far southern NJ and central and southern DE has the best chance to see the most snow of 3-6″ with 1-3 inches around Philadelphia and surrounding suburbs.  Areas farther north would see less than an inch.  A winter storm watch is in effect for far southern NJ and all of Delaware.
