Event narrative

The Automated Surface Observing System at Beverly Municipal Airport recorded a wind gust of 49 mph. No damage was reported.

Wider weather episode

The second severe weather event for the day occurred north of the Massachusetts Turnpike (Interstate 90). This severe weather was triggered by an approaching cold front from the west. The previously hard hit areas of Rhode Island and southeast Massachusetts were not affected by this second round of storms. As these storms developed across western Massachusetts, they began to produce wind gusts of 50 to 60 mph. As they continued to move eastward, unusually large hail was the main event as several locations, including Boston, had hail up to 2 inches in diameter! In fact, the 2 inch diameter hail that occurred in Boston is the largest to ever occur in Suffolk County since records began in 1950.
