The episode as NWS GYX wrote it up.
On the afternoon of June sixth a progressive shortwave trough approached New Hampshire from Vermont. This brought moderate instability aloft along with deep level shear. These ingredients interacted with a hot and humid day for early June that led to amble CAPE that could support severe thunderstorm outflow winds. A line of storms developed in Vermont and progressed across the Connecticut River Valley into New Hampshire bringing with it gusty outflow winds that brought down trees.
The Burlington radar (KCXX), 112 km away, was scanning. The volume nearest the first event began at 00:25 UTC.
