"I WONT HAVE TO EAT THE ENTIRE CROW, BUT I MAY HAVE TO EAT PART OF IT!
Just wanted to alert you that my thinking may have to be altered for parts of the area. No, there won’t be a foot of snow anywhere, not even close, but there may be more than the light coating I spoke of earlier. The upper level system associated with this precipitation event tomorrow night is so strong that it may literally manufacture enough cold air to produce accumulating snow for a few hours. When air is lifted, it cools, and stable air cools more than unstable air. So vigorous upward motion in a stable air mass can produce significant cooling over a deep layer. That will be the key tomorrow night. We can’t rely on cold air damming, and the true arctic air is west of the mountains and unavailable. So the only hope for snow lovers is to manufacture the cold air via strong upward motion. Stay tuned!"
