From the storm reports

Narratives as filed with the NOAA Storm Events Database (public records; lightly trimmed for length).

May 17, 2025 · 0.75″ (penny)

Dime size hail reported.

May 18, 2017 · 1.5″ (ping-pong ball)

A destructive hail storm and destructive thunderstorm winds caused considerable damage along Potash Bay road and Lake street. Hail stones of 1 to 1.5 inches in diameter blown by 60-80 mph winds produced numerous holes in siding, dents on vehicles and broken windows in the most severe occurrence on Lake street. Hail damage as witnessed in this survey is highly unusual in Vermont and northern NY.

July 23, 2012 · 2.0″ (hen egg)

Larger than golf ball size hail.
