What the National Weather Service wrote

Mesonet site XLAR at Larchmont Harbor measured a 34 kt wind gust.

The wider storm

With the area warm sectored, MLCAPE values increased to 500-1000 J/kg through the afternoon. Falling heights aloft from an approaching upper level trough and a cold front at the surface were able to produce enough lift to spark a broken line of showers and thunderstorms. One portion of the line became severe and produced damaging wind gusts over the waters.

Began near Larchmont Harbor Wxflow (40.9200, -73.7300).
