Winter Storm in Southern Coos, 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. Snowfall on the northern side of persistent banding was a little more elevation dependent. Snowfall ranged from 2 inches near the Connecticut River Valley to 10 inches in the White Mountains. Snow was heavy and wet, clinging to branches and breaking limbs. Power outages increased in the late afternoon, but the power outage rate was less than 5 percent for the county. Key Impacts: heavy snow, isolated 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.
