I don't get the reduced snow depths along the immediate shores. The warm air is not coming in from the ocean, it is coming from the SW at 850mb and above.
That's an interesting point. When I look at the soundings in the regions depicted as sleet on the maps, I see the only violation of 0c is the narrow nose right at 700mb. In reality, I wonder if it is sleet mixed with snow that forms below 700mb?
Saturday record low maxes possible. Can you imagine NYC with a high of 6f? I wonder what it was in SLK that day.
