What happened

The episode as NWS GYX wrote it up.

An area of low pressure moving northeast from the Carolinas on the morning of the 29th combined with a low dropping southeast from Canada to form an intense area of low pressure that moved through the Gulf of Maine during the early morning hours of the 30th. Much of New Hampshire received between 6 and 16 inches of snow with lesser amounts along the Connecticut River Valley. Along the Seacoast, most of the precipitation fell as rain with only an inches or two of snowfall accumulation. Inland from the coast and across southern areas, the rain changed to a heavy, wet snow which clung to trees and wires which resulted in scattered power outages. More than 11,000 homes and businesses saw outages due to the storm.
