Winter Storm in Sullivan, New Hampshire

While snow began early in the morning on the 28th, snowfall rates picked up late morning through late afternoon. Snowfall rates where one inch per hour at times, especially once you got out of the lower elevations of the Connecticut River Valley. Snow was heavy and wet, clinging to branches and breaking limbs. Power outages increased in the late afternoon, and the power outage rate was around 10 percent for the county. Snowfall totals ranged from around 3 inches in the valley to 8 inches in the higher elevations near Sunapee. Key Impacts: heavy snow, power outages.

Early on the 28th an area of low pressure was tracking through the Ohio River Valley. By daybreak a secondary area of low pressure was developing in the vicinity of Chesapeake Bay, and would become the primary low pressure center by midday as it neared Long Island. The marginal temperatures of the early season air mass and easterly winds bringing warmer marine air inland meant that much of the initial precipitation fell as rain. By late afternoon precipitation type in marginal areas was flipping to snow as the precipitation rate increased. Snow continued into the late evening before winding down. It was a wet, heavy snowfall that was elevation dependent with small changes in elevation having significant differences in amounts.
