Stupid Dryslot

It's going to be close around here.  The shortest-term models we have are slightly east of the NAM positions yesterday which isn't that good for us.  I think the gradient of snow shifts east a bit and we're talking lower totals of 1-3 inches here in the DC Metro with less to the west and more up around Baltimore.  I felt pretty confident about 2 inches yesterday and I still think so.

Still reviewing data this morning.  There's even less consensus as you get to small-scale modeling and a lot of it will have to be figured out once the snow starts.

You can see the eastward shift in the NAM in this precipitation total forecast map (compare to the one in the post just below this).
