Lunchtime update: The latest GFS has come around to a Euro type solution...so stay tuned.
Regarding next Tuesday's system.
The GFS drives the storm over the central Great Lakes so by Tuesday morning the storm center is just east of James Bay. This solution would give a most rain event with a brief change over to snow as the trailing cold front comes through.
The Euro takes the storm just south of the lower Great lakes (Erie & Ontario) such that the storm center is over northern New York state Tuesday morning. This solution would give us another thump of heavy wet snow.
Guess which solution I'm rooting for.
