What happened
The episode as NWS ALY wrote it up.
A stalled frontal boundary across the Berkshires interacted with a strong upper level disturbance from July 15 into early July 16. The result was a slow moving low pressure area which formed over Virginia. This low pumped a deep layer of tropical air into the region and resulted in a significant rainstorm. Rainfall amounts ranged from 1.85 inches at North Adams to 5.81 inches at Great Barrington. The heavy rain, resulted in some flash flooding. County Route 40 was flooded at Shefield and closed for awhile. Flooding was noted in Great Barrington, with many roads closed, and sewers backed up.
The radar
The Albany radar (KENX), 74 km away, was scanning. The volume nearest the first event began at 23:51 UTC.
