Clipped With Snow Showers In Spots Tonight

Attention for everyone has turned to Friday's "storm" as the main course for the appetite of the snowstarved. While snow is still on the table for Friday, the system as of this morning is a bit less robust in modeling, thanks in part to this clipper that's coming on southeast through the Lakes for tonight.

This clipper won't produce much snow but its mid level energy is robust and enough to fire up a couple of bands of snow showers given it has some lake-enhanced moisture to work with.   The first band of snow showers could work through areas north of the city later this afternoon into the evening (as modeled below on the NAM computer model).  The Poconos could pick up a coating or perhaps a dusting from any snow showers that work through there later today...this part of the system is more lake-fueled than what passes to our south tonight with the main energy but it's something to note if you're traveling north later on today.

The clipper's main thrust of energy will pass to our south overnight, spreading snow showers through West Virginia, Maryland, and into Delaware.  It's possible anyone south of a Dover-Cape May line picks up some snow showers overnight as this wave of energy moves through.  In between the northern stream of snow showers and the southern "wave", flurries are possible but anything more than that doesn't appear likely this evening as the atmosphere is quite dry.

Some coating type accumulations are possible south of a Dover-Cape May line with this southern shot of energy as should pass through the southern part of the region after Midnight and pull away towards daybreak.
