Just a brief description and a video. We staged in Dubuque, IA wating for storms to fire to our west. Especially challenging chase day. Up against 60 mph storm movement and a linear tendency after initiation. As storms fired we made a late desicion to move North toward La Salle, WI. Unfortunately the target storm, now tornado warned was out of reach. The road network allowed for about a 50 mph average speed and didn't offer a lot of NE options, so it was really worse than that relative to storm motion. Nonetheless we managed to get on more than one tornado-warned cell. Eventually one cell lead us right to the storm damage path from the Initial cell we intended to intercept. A half-mile wide damage path was observed in Arkdale, WI just 30 minutes after it had occurred. Several homes were damaged and entire conifer forests were lopped off at the 15 foot level. Fortunately emergency responders were just arriving. Due to some fat-fingering mistakes the footage of the damage as we drove by was missing from my camera.
