The National Weather Service has announced that the Washington region will be under a Winter Storm Watch beginning tomorrow afternoon. And why is that? “Due to the energy associated with this storm, it’s possible localized heavy banding of snow may develop tomorrow late afternoon and evening,” reports the Capital Weather Gang’s Jason Samenow. “It’s very difficult to pinpoint where this would happen – but where it does snowfall rates could be very heavy with the possibility of thundersnow.”

Emphasis ours, obviously.
