Thunderstorms developed in a very warm and humid airmass ahead of an approaching cold front. Thunderstorms developed during the late morning hours around Adrian and then quickly moved northeast and affected the metro Detroit region. These storms dissipated early in the afternoon. However storms redeveloped across western and central Lower Michigan by mid afternoon. These storms then moved into eastern Michigan. The storms continued through the afternoon and much of the evening hours. Severe wind gusts were associated with many of these storms.
