Winter Storm in Southern Carroll, New Hampshire

Snow moved into the area early afternoon on the 5th. Snow became moderate to heavy through the late evening on northern edge of the most intense precipitation. Downsloping northeast winds and warmer temperatures resulted in significantly less snow in the valleys than the higher elevations. Snow totals ranged from 2 inches in the lower elevations to as much as 10 inches in the mountains.

An upper low ejecting out of the Rockies ultimately phased with a northern stream shortwave trough leading to cyclogenesis off the East Coast on the 5th. Low pressure formed over the southern Appalachians and moved northeast towards Nantucket by the evening of the 5th. The storm tracked into the Gulf of Maine and eventually began weakening in the Bay of Fundy early on the 6th. While the radar presentation looked like a classic northern New England snow storm, the antecedent air mass was marginal for snow and precipitation type became elevation and/or precipitation rate dependent. Most notably the snow that did fall was wet and sticky. The wet snow bonded to trees which led to downed tree limbs and widespread power outages.
