Gray Monday, Chance of Rain/Snow Showers South

A vail of overcast is in place in much of the region this morning as a weak storm system tracks to our south through the Carolinas.   The closest precipitation to us is in West Virginia this morning, with other showers across North Carolina, all generally moving east.   Overhead, some moisture is trying to squeeze out of the clouds but nothing is reaching the ground locally as the bottom atmosphere is pretty dry and dynamics above the ground aren't the greatest.   Today's generally going to be gray for much of the daylight hours, with a few breaks in the clouds from time to time...those breaks will be most common this morning.

The area of precipitation in West Virginia as well as back in Kentucky will track east into the DC area later on today, gradually working towards Delaware and South Jersey for this afternoon and early evening.  The first batch (in WV) may result in sprinkles or flakes falling south of the city after midday today, with the Kentucky batch crossing through after 5 PM with a steadier round of showers or light snow mixed in.   Model guidance generally suggests most of the precipitation stays south of a Wilmington-Long Beach Island line today and that much of it will be light.   If precipitation is a bit steadier across Delaware and South Jersey, a coating of snow to perhaps an inch may fall this evening if everything breaks right.   Don't count on much falling and sticking and it's just as possible given the light nature of precipitation on the radar this morning that this event is more liquid than frozen for the coast.

In terms of temperatures, everyone tops out in the lower 40's today.  Philly and the burbs should get to about 43, with everyone else just notching above 40 for a time just after midday.  Winds will be light but with the general lack of sun through much of the day it won't exactly feel too warm out today.
