Event narrative

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

Wider weather episode

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.
