Euro has the chance of the first synoptic snow of the season across the NNE mtns, especially the mtns of NW Maine. Low levels may be borderline, but E-NE flow banked against the high terrain may help cool it a tad. Elsewhere, a fascinating temp gradient exists between, say, BOS to DC. Euro has +22C at 850 in the Mid Atlantic. That's just amazing to see. It looks like we'll be in the 40s and 50s with rain Thursday and Friday. Interior likely below 50 one or both days.
