What happened

The episode as NWS GYX wrote it up.

Broad shortwave crossing southern Canada pushed an associated cold front into southern Canada during the early afternoon. A pre-frontal trough moved into eastern New York during the early afternoon with individual cells and line segments forming into one large squall line with bowing segments. The squall line pushed into central and southern new hampshire by mid afternoon and reached the coast by early evening. Good heating ahead of this line with dew points in the upper 60s to lower 70s resulted in capes of 1500 to 3000 j/kg across much of the region. Although shear was limited, stronger cells moving around 35 kts transported strong mid level winds to the surface resulting in numerous reports of wind damage. Stronger cells also produced quarter to golf ball size hail. One long lived cell in Kennebec County produced hail at least 3 inches in diameter.
