Milder temperatures have been shrinking parking lot snow piles, but it won't continue for much longer. After a weak disturbance passes through to our north in Canada tonight, bringing a few drops and possibly a couple of snow flurries, the forecast gets very tricky.
A potent storm is brewing in the Midwest that will bring precipitation our way by sunrise Wednesday, but how much will be snow and how much will be rain isn't clear.
But, before the winter storm arrives, the temperatures will be almost warm. Many backyard thermometers in the Twin Tiers will read temperatures well into the 50s Tuesday afternoon. Overnight Tuesday into Wednesday morning as the precipitation begins, it will most likely begin as rain. At some point Wednesday, a rain/winter mix will transition to snow.
Typically, this close to a snow event there would be reasonable confidence regarding likely accumulation. However, our area will be very close to the division between rain and snow for much of Wednesday with this system. Now, accumulations could range between 2-12" of snow from northern Pennsylvania into southern NY. Late in the week into next week, cold air settles back into the northeast.
