Here is 925 prior to the onset of the euro op. That's a mild airmass to start. You got temps NW of Maine above 0C at 925. Look where the good stuff his. Next to Ray's Golds Gym nipple low NW of Toronto.
Sure this can be overcome, no argument there...but it will depend on being in the real meat of this stuff, especially below 600' or so. If you expect 2-4" then nothing to worry about. But for 12" plus, I think you need a lot to go right.
