Although the day began with clouds, breaks in the clouds during the afternoon hours allowed the atmosphere to become unstable over the Catskills and mid-Hudson Valley of eastern New York.  As a surface trough and upper level shortwave approached from the Great Lakes, thunderstorms broke out over the region.   Although the thunderstorms weren't overly tall, strong winds aloft allowed the storms to rotate and produce damaging wind gusts, mainly to trees, across Ulster and Dutchess Counties during the evening hours.  With the loss of daytime heating, thunderstorm ended by the late-evening hours, ending the threat for severe weather.
