First storm beginning to wind down; Next Storm on the Horizon

Our snowmaker from Friday is beginning to wind down...with only some deform precip located over VT/NH/southwest Maine left. Storm rapidly pushing off shore and out to sea. In it's wake, Saturday should be a nice day across much of the Northeast before clouds beginning advancing northward from the Mid-Atlantic ahead of the next system slated to affect the northern Mid-Atlantic/Northeast Sunday and Monday.

At the present time... it appears likely that many areas from Pennsylvania to Maine will see wintry precip from this in the form snow. ATTM, this looks to be mainly a widespread advisory event along/west of I-95/east of I-79/south of I-90. This is in response to a Double-barrel Low pressure system advancing northeast up thru the Ohio Valley before handing off its energy and forming a Low Pressure along the Delmarva coast. From there it will track northeast to a position near Cape Cod Sunday night.

As of right now...current guidance suggests along and north/east of I-87/I-90 corridor (Capital District and points north/east) stand the best chance for significant snow in excess of 7". As Low pressure reaches Cape Cod...it is forecasted to deepen rapidly and undergo bombogenesis as it tracks into the Gulf of Maine by Monday. This will deliver a widespread moderate-heavy snowfall across central/northern New England before storm exits into the Canadian Maritimes. Along with the snow... very strong winds will also plague the region resulting in near blizzard conditions across the interior. Coastal sections of New England from Boston thru downeast Maine will be a close call regarding whether significant snow will reach the coastline. 0z NAM brought the Low pressure ashore into southeast MA and into central Maine. This track would yield a snow to rain scenario across much of southeast MA/downeast Maine. It should be said that the final storm track is not set in stone... which will determine how much snow coastal sections of Massachusetts/Maine see. More on this storm Saturday Morning. Stay Tuned.
