Original Story:
Initially the National Weather Service forecast 2-4 inches of snowfall in the region; however, the discussion suggests that residents may see more.
" I am concerned that east-west oriented banding may cause locally higher amounts across these areas," a NWS forecaster said. "The guidance continues to trend heavier, so it is quite possible an additional upgrade of headlines and forecast totals could be in the offing."
An alert sent by Prince William County warns that residents could see 8-12" by the conclusion of the storm.
