What the National Weather Service wrote

The sailing vessel Eyebrow reported a 42mph wind gust. No damage was reported.

The wider storm

A pre-frontal trough moved into southern New England, providing lift for showers and thunderstorms to develop in a hot and humid atmosphere. In addition, CAPE up to 2000 J/kg and 30-40 kts of shear provided enough instability and shear for thunderstorms to become severe. Because of warm air aloft, these thunderstorms mostly produced strong to damaging winds and not large hail.

Began near Barnstable Harbor (41.8300, -70.3700).
