High Wind in Lawrence, Indiana

Non-thunderstorm winds downed a couple trees near Williams.

Tropical Storm Helene transitioned into a Post Tropical Storm while tracking from the southern Appalachians into eastern Kentucky during the midday hours of the 27th. The circulation center then tracked west across Kentucky while the northern portions of Helene's remnant pressure field enveloped the Midwest. As the system continued to transition into an overall baroclinic circulation, the tilt of its asymmetric, increasingly oblong trough retrograded from the upper Ohio River Valley into Indiana, aligned along the Interstate 69 corridor by the early evening hours.

Helene's strongest gradient through the mid- and low levels was found along this axis that crossed Indiana from east to west. Severe winds aloft mixed down to the surface during mainly late day hours, as wind gusts that approached 70 mph. Isolated to scattered wind damage was found over much of the region, including scores of downed trees; one of which that caused one injury in Putnam County. Power outages for central Indiana peaked at 132,381, making up nearly 80 percent of the state's total.

A band of heavier rain across southern Henry County, northern Hancock County and most northern portions of the Indianapolis Metro Area produced 1.60 to 2.70 inches of rainfall, leading to brief localized flooding and ponding of low-lying areas.
