Isolated severe thunderstorms moved across parts of eastern New York ahead of a cold front on the 21st of August. An F1 tornado skipped 3 times along a 1.2 mile path in Fort Miller where it downed a 60 foot high concrete silo, tore sheet metal from two barns, removed part of the slate roof of a house, toppled a camper trailer and blew windows out of two houses. One man was slightly injured receiving minor cuts from flying glass. In Marathon and Messengerville severe thunderstorm winds downed trees. In Edwardsville lightning was believed to be responsible for a barn fire during an early morning thunderstorm which totally destroyed the storage barn.
