Episode Narrative In the early evening hours of July 19th, Severe Thunderstorm Watch 605 was issued in anticipation of severe thunderstorms developing in the vicinity of a low level moisture convergence axis and an approaching mid level short wave trough. In addition, strong diabatic heating and cold air advection aloft produced steep mid-level lapse rates which resulted in destabilization of the atmosphere. Several severe thunderstorm warnings were issued. Several reports of large hail and one report of a severe thunderstorm wind gust were received during the evening hours.
Event Narrative A trained spotter reported an estimated severe thunderstorm wind gust of 60 mph.
