Wider weather episode

Weak low pressure formed on the morning of the 15th along a stationary boundary and moved up the Ohio River Valley and into the Northeast through the 16th. The system occluded and continued to move northeast, with the triple point passing south of southern New England. Secondary low pressure began to develop at the triple point on the afternoon of the 16th, rapidly deepening as it departed through the Gulf of Maine. The approach of a kicker shortwave helped to maintain an inverted trough northwest of the departing low, concentrating an area of snowfall over parts of eastern New Hampshire and western Maine.
