Cold air can come roaring in here from the N-NE…especially with some evaporative cooling assist if we get some precip into Maine. You should have no problem with NW too since you upslope on that flow.
I think the euro will cool some, but find it hard to believe it will completely cave toward the gfs. That would be a large scale thermal failure.
EC easily has the best H85 scores at d3. Sad Navy right there too.
