Severe Thunderstorms and Heavy Rain in the Central US

Isolated to scattered strong to severe thunderstorms may produce damaging winds and hail in the upper Great Lakes into the central High Plains. Heavy rain may create localized areas of flash flooding over parts of the Central Plains and Middle Mississippi Valley. Showers and strong to severe thunderstorms are possible over parts of the Mid-Atlantic. Read More >

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.
