Latest snow map. Just a few adjustments. Trimmed back a bit on the 12-18" range. The 0z NAM is actually very similar to what I am thinking. The heaviest snow will be from NW Jersey towards north central Mass. due to the storm bombing out just off shore and the moist flow off the ocean hitting the mountains enhancing snowfall. I chatted a little with someone who lives in the mountains in norther New Jersey who said they usually don't pick up that much snow in that situation, so tomorrow when some of the high resolution short range models come out I may adjust the heavier axis of snow...but for Tonight I'm sticking to my guns! On the mixing scenario...the 0z NAM indicated that NYC and Boston would see rain at least to start and then change to a short (less than 6 hour) period of moderate/heavy snow for both cities. Just outside both those cities, especially above 600-700 feet it will be mostly snow. Another note: with temperatures so marginal for snow, the snow will be wet and heavy, which could bring down some trees and power lines. Also, the Great Lakes and northwestern Appellations will be affected by a weak clipper slowly moving through which will put down a general coating to 2". However, late Monday into Tuesday we will have a bit of a lake effect situation, so favored lake affect zones could see over 6" out of this whole thing. Tomorrow: Long range...specific Ohio forecasts. (I am OHweather!)
