The episode as NWS DTX wrote it up.
On June 10th, daytime heating pushed temperatures into the upper 80s and lower 90s, combining with surging humidity to drive heat indices near 100 F and create a highly unstable environment with MLCAPE values reaching 2,500 J/kg. Weak low-level convergence initially triggered severe storms over Wayne County, which dropped 1 to 1.25-inch hail across Dearborn and Dearborn Heights. Later in the evening, a destructive Midwestern squall line tracked into southern Lower Michigan, though it steadily weakened as it moved through Southeast Michigan before completely clearing the state by midnight. While the broader system left over 85,000 customers without power statewide, wind damage, downed trees, and power outages within Southeast Michigan remained isolated to scattered, impacting communities primarily along and west of U.S. 23.

NWS Detroit, MI wrote its last area forecast discussion before the first event at Jun 10, 2:15 PM EST, 1 hour earlier.
