A clipper system has moved offshore in the Northeast, leaving a cold NW flow in place in its wake. The cold air created heavy lake effect snow on Tuesday, leading to power outages in Western Michigan, particularly in Muskegon which recorded its snowiest October day on record with over 8"! Additional snow, mostly lake effect, will continue to fall on Wednesday before the cold flow comes to an end through Thursday morning.
Temperatures are now in the 40s and even 30s for daytime highs, cold enough to support snow for many areas of northern New England and western/central New York. Highs return to above average by Thursday or Friday.
