An active severe weather season for Southeast Michigan continued on July 24, 2021 with another round of severe thunderstorms and tornadoes. Thunderstorms initially developed mid-afternoon just south of Cadillac and tracked southeastward into the Tri-Cities and Metro Detroit regions through the evening. Storms began as a broken line and strengthened quickly as they moved into a region of favorable dynamics and ample instability. Embedded rotation within this line produced three confirmed tornadoes in White Lake, Armada, and Clayton Township. An additional tornado spun up over Port Austin. Numerous reports of straight-line wind damage, namely power outages and tree damage, were also observed with many of these reports coming from western Oakland County. As the line of storms tracked south of I-94, the tornado threat diminished; although bowing segments embedded within the line continued to produce damaging wind gusts. In addition to wind damage, most areas observed 1-2 inches (with locally higher amounts) of rainfall which led to flash flooding in some low-lying and flood-prone areas. At least 140,000 DTE customers lost power at the height of the storms. Between the tornadoes and wind damage, Oakland county was estimated sustaining close to 10 million dolllars in damage, with around 4.5 million across Macomb county.
