What happened

The episode as NWS ALY wrote it up.

On October 8 at daybreak, a nearly stationary cold front was over southwestern New England. The air over the northeastern United States was very moist. Low pressure in the vicinity of the eastern Carolina states moved slowly north northeast along the cold front. Heavy rain fell over the southern Berkshires through the early morning hours of October 9. During this period, there was over 6 inches of rainfall in much of western New England, triggering widespread flooding. Several evacuations of people from their homes occurred.
