The wider storm

A stationary front stalled over southern New Hampshire on the evening of June 6 into midday on June 7th. Repeated rounds of heavy rain and thunderstorms brought up to 4 inches of rainfall to areas across Merrimack and Hillsborough Counties between 3 and 7 PM. The heavy rain with rates measured over 2 inches per hour at times, was sufficient to cause flash flooding with multiple roads flooded, some with washouts, and some property damage. Numerous severe thunderstorms also developed on the afternoon of June 6th as amble instability and moisture interacted with the stalled front boundary. Large hail and damaging winds were reported.

Began near Bow Center (43.1400, -71.5800).
