An organized line of thunderstorms brought widespread strong to severe thunderstorms across southeast Michigan. Thunderstorms initially became organized across the Tri-Cities and northern Thumb during the early afternoon and brought widely scattered wind gusts between 50-60 mph, which resulted in numerous reports of downed trees and powerlines. Severe thunderstorms continued to expand southward during the late afternoon, while new storms developed just ahead of the initial line, along an expanding outflow boundary. Given the moderate to strong instability in place, thunderstorms continued to produce widely scattered damaging wind gusts as they approached the northern Metro region. A Mesoscale Convective Vortex (MCV) eventually caught up with the line in the evening hours which continued the threat of severe weather across the Detroit Metro region. Over 100,000 homes and businesses were without power after the thunderstorms moved through.
