Premium: Friday AM snow potential hazards analysis

Forecast models have trended farther northwest — and stronger — with a low pressure system, which is forecast to develop on a frontal boundary off the East Coast from late Thursday into Friday. This is the same frontal boundary which is crossing the area this evening, and its eventual positioning offshore will have significant impacts on the forecast evolution.

Models suggest that as the frontal boundary moves offshore, a secondary area of energy in the mid levels of the atmosphere approaches the area. This energy provides enough lift for precipitation, with sufficient moisture, and snow will re-develop to the west of the offshore front. A favorably positioned 250mb jet streak could enhance precipitation on the northwest side, bringing light snow to the New Jersey, New York City, Long Island, and Southeast Connecticut on Friday morning.
