A weak mid-level trough, low-level jet, and low-level boundary combined with typical lake breeze convergence zones and a modestly unstable environment to produce isolated strong to severe thunderstorms across many parts of the forecast area. Other than a half inch hail report in Chautauqua county, wind damage was the main report type in the Southern Tier storms, while a severe wind and isolated flash flooding were the report types with storms farther north.
