Map! First Guess:
DC - 16"
Dulles - 20"
Charlottesville - 20"
Fredericksburg - 15"(Some sleet)
Richmond - 7" with a lot of sleet
Roanoke - 8" - Sleet and freezing rain too
Frederick Maryland -20"
Baltimore - 22"
Bowie - 22"
Annapolis - 22"
Dover 22"
I also have concern that NC will see a serious/severe ice storm in some of the valleys. ALSO, flooding in Southeastern VA and a lot of North carolina that has snow pack is possible!
Serious situation!
