Overview

A cluster of strong storms over southern lake Michigan, around 6 AM EDT, organized further as they tracked into northwest Indiana/southwest Michigan which prompted initial severe warnings based on deep cores (50dbz > 40kft) and emerging wind signatures. The most intense line segment peeled east-southeastward and hammered Elkhart, Kosciusko, and Whitley counties with widespread wind damage. An initial 70mph wind gust was recorded followed by a second 73 mph gust around 3 min later with a microburst core over Kosciusko County. The eastward leading convective line proved more vigorous as it aligned with the low-level shear vector and produced additional wind damage into northwest Ohio (Van Wert county). Additional intensification occurred to the west within the larger line segment with gusts 58-62 mph noted in AWOS METARS from Monticello east to Grissom Airports.
