New GFS run shifts to the northwest:
This is just one run from one model, but it's not what you want to see if you're looking for a big snowstorm on Long Island. After the models have been so consistent, this was bound to happen though, and until other models show it, I wouldn't put too much faith in this one run. Check out those snow totals inland though! The 2nd and 3rd images are for Thursday at 1 AM and 7 AM.
