The episode as NWS IWX wrote it up.
A moderately unstable, but weakly sheared environment was in place across the region. Several outflow boundaries acted on these ingredients, allowing for pulse-type thunderstorms to develop. The majority remained below severe limits. However, several reports of wind damage were received in Huntington County.
