Nothing like a widespread snowfall before an arctic snap arrives. We picked up over a foot of snow in the higher elevations north of the Mohawk Valley. The valley locations saw less, but there was still plenty of tough travel to be had across the area, with snowfall rates exceeding 1" per hour during the middle of the day.
Moving forward, we have much colder weather settling in. The polar vortex is indeed heading in our direction, but we aren't going to take the brunt of the coldest air (at least, not like the Midwest).
Before the cold settles in, one more arctic front arrives tomorrow afternoon. The dynamics that could produce snow squalls look to be just south of the area, but it will be a close call. Be on the lookout for a round of snow followed by windy weather. Wind chills plummet tomorrow evening to -10 to -20. By Thursday morning, wind chills drop to -20 to -30. The wind chill will likely stay below zero all of Thursday and most of Friday, before finally breaking Saturday.
While all this cold weather is going on, the lakes are going to roar to the north. Heavy lake effect snow is expected along the Tug Hill and North Country, with 2-3 feet possible in the Tug. The band is expected to stay entirely north of the Mohawk Valley this time around.
A major shift in the jet stream will break us out of the cold for the weekend and beyond.
