This week’s storm presents a rare case: a disturbance tracking to our west is going to produce a measurable snow storm. This is due in part to some redevelopment off the coast, but the primary driver of this event is a vigorous upper-level low.
The map above is the surface forecast for 10pm tonight. Note the tightly wrapped low over Lake Ontario. As far as accumulations, the last model run has backed off the qpf and I’m calling for 2-4 inches of snow in the Catskills, 4-10 in the Adirondacks, and 6-12 along the top half of the Green Mountain spine in VT. Models are showing from .5-1 inches of liquid equivalent.
There may be some more on the backside snow in favored upslope areas. As is often the case with storms on the east coast, wind will be a issue late Friday and Saturday and may effect lift operations.
