My first maps for this intense storm are staying pretty wide open. The models still agree on at least a sub 984 low affecting the region with over 2 inches of water, however the track has gotten more uncertain in the last 24 hours. A shift of 50 miles could be the difference between 2 inches and two feet of snow.





The first map is accumulations for Sunday, the second one is for Monday, and the third is the total of the two. While the storm will continue to affect the region through Wednesday, accumulations will be minor with respect to what is in store for Sunday and Monday.
