An unseasonably warm and moist airmass for early March worked into southern New Hampshire during the day on March 7th.  This allowed for increased instability ahead of an approaching cold front.  A surface low pressure system and associated cold front tracked across the region from the Ohio River valley during the evening.  Strong westerly surface winds were advecting cold polar air behind it.  A continues fine line of low-topped thunderstorms developed on the cold frontal boundary across southwest New Hampshire.  This line progressed eastward through the evening, downing numerous trees and powerlines before weakening as it reached the Merrimack River Valley.
