Thunderstorm Wind in Parke County, Indiana

Thunderstorm straight line winds damaged a garage in the Bridgeton community and a small barn and large shed on Mansfield Road, with a couple trees onto houses, and Indiana Route 59 closed from downed trees and power poles.

On April 2nd's early evening, an upper level short wave disturbance crossing the Middle Mississppi Valley, and associated 1000-mb surface low pressure tracking quickly from Iowa to Wiscomsin, placed central Indiana within its warm sector. The conditional set-up for severe weather included steep 0-3 km lapse rates, and corresponding DCAPE values of 500-800 J/kg extending along and just east of the Wabash Valley. A resultant quasi-linear convective system (QLCS) crossed western central Indiana, producing widely scattered damaging straight line winds. The system's overall high cloud base mitigated any tornado production except where a brief EF-0 was spawned in Parke County.
