Winter Storm in Western and Central Hillsborough, New Hampshire

Light snow overspread the area in the evening on the 15th. This continued into the morning of the 16th when an area of strong warm air advection resulted in a laterally translating band of moderate to heavy snow. This swept through the region by the afternoon of the 16th. Periods of snow continued into the late evening of the 16th, mixing at times with sleet and/or freezing rain within the mid level dry slot. Snowfall totals ranged from 7 to 11 inches. Key Impacts: Heavy snow.

Low pressure began to develop early in the day on the 15th across the lower Mississippi River Valley. A warm front northeast of the low center sharpened and lifted north towards the New England coast by the evening of the 15th. Light snow developed north of the warm frontal boundary and continued into the morning of the 16th. The storm continued to gradually deepen as it tracked through the Appalachians, becoming more organized by the middle of the day on the 16th over the Mid Atlantic. The strongest lift and heaviest snow developed at this time and a laterally translating band moved through much of northern New England through the day. More intermittent periods of snow and sleet continued in the mid level dry slot of the system into the early morning hours of the 17th. The highest snowfall totals were closer to the coast, but by the end of the storm a deep, dense snow pack remained across the area.
