The episode as NWS IWX wrote it up.
Numerous showers and thunderstorms developed ahead of a low pressure center which moved through the area. With moderate instability and shear, numerous severe storms developed with several reports of damaging winds. In addition, storm motion nearly parallel to the frontal boundary caused training storms and localized flooding in a few locations.
