Areas in northern VA, MD, DC and Delmarva could see 1-2″ of light snow today as a clipper system moves over the region. I was thinking 0.5-1″ earlier, but with the radar filling in and areas of moderate snow forming, higher amounts are expected, with some areas possibly even going over 2″. The band setting up between Frederick and Hagerstown, MD is particularly concerning:
EDIT: Looks like 0.5-1″ was the way to go… the radar didn’t fill in nearly as nicely as it was looking originally. Add small flakes that easily melt and you got 0-1″.
