Strong heating and high moisture levels supported extreme instability ahead of thunderstorms that initially developed to the northwest along a pre-frontal boundary aided by forcing from a positively tilted upper trough. Thunderstorms eventually merged into a severe QLCS that marched south and southeast through the entire forecast area, producing widespread wind damage. In terms of the number of damage reports, this was the most extensive severe weather event in our area since 2006.
