A fairly buoyant and moist air mass resided over our area. The main upper level jet was over western Lake Erie, with a trailing upper level shortwave over southern Michigan during the mid afternoon. Both of these neared western New York by late afternoon into early evening. As these upper level features interacted with subtle lake breeze boundaries, there was a rapid increase in thunderstorm coverage across the Niagara Frontier. Storms blossomed across Niagara, Orleans, and Genesee counties. These storms rapidly became severe, producing some damaging winds and large hail. These storms all appeared to be rotating, helping them to maintain their severity for an extended amount of time.
