Nor am I, but I gather temperatures between -12 to -18C in the DGZ with sufficient lift is most important for ratios. Surface temps don't make that much of a contribution.
I recall some posters down there saying "f&*k New England" when we were trying to sneak minor goodies from storms that nailed them, so schadenfreude away!
Yeah, guaranteeing 2' is a bad proposition. You're just setting yourself up for disappointment. But guaranteeing no one sees it is also silly. It can happen under the right circumstances, even in a relatively short duration storm.
