Low pressure tracking into the southeast states will pulls moisture from the Gulf of Mexico, as well as tapping into the energy of former tropical storm Olga. The strong storm system will turn northward towards the Ohio valley, transfering energy to the NC/VA coast. This will develop a very intense coastal low that bombs out as it moves northward. The exact track of the low will determine whether or not we stay all snow, and how much water equivalent can be expected. At this point, expecting a swath of 1+ inches of water across PA, NY, and into New England, with all snow likely in VT, NW MA, and W/C NY.
Track changes will occur with varying strengths of high pressure in southeast Canada and timing of the tropical connection with Olga. See my post from yesterday on the full details of the storms variables.
