What happened
The episode as NWS GYX wrote it up.
A strong upper level trough was digging into New England on the afternoon of July 26th with an associated cold front approaching the region. Instability was marginal with CAPE's of 1000 j/kg or less generally pooled ahead of the front. However... dynamics associated with the shortwave and moderate to strong low level shear produced numerous severe cells with large hail and damaging winds. In addition ...heavy rain with some of these storms resulted in flash flooding and road washouts.
