An area of low pressure developed off the coast of North Carolina Saturday morning, October 29, then moved north to just east of the Delmarva Peninsula by Saturday evening, and through the Gulf of Maine Saturday night.  The storm brought a heavy, wet snow to southern and central New Hampshire.  Snow began to fall across southern New Hampshire late Saturday afternoon, became heavy during the night, and ended before 7 am Sunday morning.  The snow was mixed with rain along the immediate coast.  The combination of the heavy wet snow and leaves still on the trees caused numerous trees and branches to snap and fall, causing widespread power outages.  About 315,000 customers lost power during the storm, mostly across the southeastern part of the state.  Some customers were without electrical service for almost a week.
Snowfall amounts were quite variable across the state with southern areas and the higher terrain receiving the most snow, and in some cases, record snowfall.
In Merrimack County, the official NWS observed 1-day snowfall at Concord was 22.2 inches while trained weather spotters reported 25.8 inches in Bow, 21.7 inches in Dunbarton, and 20.0 inches in Chichester.  In Belknap County, trained weather spotters reported 17.9 inches in Belmont and 17.5 inches in Tilton.  In Carroll County, trained weather spotters reported 18.5 inches in Wakefield and 16.3 inches in Wolfeboro.  In Strafford County, a trained weather spotter reported 17.0 inches in Strafford.
