I strongly believe there will at least be a band (if not continuous then broken) of 8-12″ somewhere from this storm. In this update, I placed it where I think it will be most likely, but would not be surprised if it shifted north or south. It is really hard to pin down the area of best banding, so I won’t be too hard on myself if it doesn’t end up where I have it.
I tweaked the northern and southern edges as well now that I have higher confidence in the forecast where these gradients are. Basically everyone has the same to higher snowfall compared to my initial map. Add the cold and wind to this event and it’s gonna be a fun day to be outside. Areas around DC northward should stay below freezing through Saturday morning, so this snow pack should have some real staying power!
