18 GFS is a perfect hit for RVA. Snow depth map is insane. Between 2am to 8am avg close to 2” per hour or close to it. Again I’m NOT saying it’ll happen. But GFS has consistently shown snow for days. And Euro, CMC and other models are on board for at least some snow. Yes warm ground etc, but those rates with plummeting temps and the first complete rush hour morning drive in a while will be rough.
