Thunderstorm Wind in Montgomery County, Indiana

Power pole and tree snapped by thunderstorm wind gusts. Extensive damage reported across much of the county with over 4000 power outages.

Pre-dawn thunderstorms on the 29th brought more large hail, to southwestern counties, with golf ball sized hailstones (1.75) reported in both Youngstown (Vigo County) and south of Vincennes.

Organized severe winds then returned on the afternoon of the 29th when a decaying derecho produced widespread significant tree damage from west-central Indiana into the Indianapolis Metro, with noticeably less expansive damage continuing across the region's southern counties. Highest observed wind gusts were 74 mph at the Crawfordsville Regional Airport and 70 mph at Indianapolis Int'l. More than 75 percent of Clay, Vermillion and Vigo Counties were each without power amid scores of downed trees; more than 250,000 power outages occurred across the state.
