Thunderstorm Wind in Martin County, Indiana

Thunderstorm straight line winds followed approximately 800 to 1700 feet southwest of the center line track of the corresponding EF2 tornado from its start location (where estimated 77 mph winds collapsed a farm outbuilding on Haw Creek Road) to at least as far as the Shoals 8 S COOP station (where 3 trees were downed around the house with several more downed to the east of Windom Road). Fifteen power poles were reported broken from the storm's winds along Windom Road with lines on the ground.

An afternoon severe weather outbreak was organized by an approaching cold front and fueled by 2000-3000 J/kg of CAPE courtesy of high lapse rates aloft, surface dewpoints in the low to mid-70s, and cooresponding temperatures as high as the mid to upper 90s over western central Indiana. Numerous rotating supercell thunderstorms developed over western central Indiana in the early to mid-afternoon and proceeded to the east-southeast through central and southern Indiana. These cells produced penny or larger hail over 16 of the region's 39 counties, more isolated straight line wind damage to trees, barns and roofs, and four EF1/EF2 tornadoes within a 33-minute period along the I-69 corridor south of Indianapolis. Each tornado was spawned from a separate supercell: an EF2 that impacted residential communities in northwestern Johnson County, a pair of EF1s that tracked across rather rural portions of northern Daviess/Martin Counties and southwestern Monroe County, and finally a longer-track EF2 that crossed far southern Martin County, killing 1 person and injuring another when destroying a rural residence, before ending its track in extreme northeastern Dubois County. The end of the event saw, amid the weakening cluster of supercells, three cells produce isolated large hail over eastern central Indiana, with also wind damage to two barns in the Seymour area.
