Winter Storm in Eastern Hillsborough, New Hampshire

Heavy snow managed to lift into parts of southern New Hampshire. The heaviest snowfall was on the morning of the 23rd into the early afternoon before tapering off. Though it was not frequent, Manchester-Boston Regional Airport did observed blizzard conditions intermittently into the early afternoon. Snowfall totals ranged from 5 to 9 inches.

Low pressure began to develop over the Southeast on the morning of the 22nd. By the evening it had moved to a position off the Carolinas and was deepening rapidly. Between 7 pm on the 22nd and 7 am on the 23rd, central pressure in the storm dropped from 991 mb to 966 mb. The intense low pressure combined with high pressure around 1045 mb building into Quebec to produce a strong pressure gradient across the region. The result was strong wind gusts through much of the day on the 23rd. While the heaviest snowfall remained largely over southern New England, the edge of the heavy snow did move into southern New Hampshire. The combination of the two produced blizzard conditions and near-zero visibility at times. While winds continued to gust into the evening, snowfall tapered off in the late afternoon hours on the 23rd.
