A strong cold front moved into the Great Lakes region during the early morning hours of the 25th. Ahead of this cold front, unseasonably warm air surged northward into the Great Lakes. Thunderstorms developed ahead of the cold front late in the afternoon of the 24th and continued into the evening. These thunderstorms extended from the Great Lakes all the way to the deep south. Strong winds just off the surface allowed some of the thunderstorms that developed across southern Michigan to become severe. Most of the severe storms caused damaging winds gusts associated with strait line microburst winds. However, increased low level directional shear via a surface warm front that extended across southeast Michigan allowed some of the thunderstorms to develop rotation, a few of which produced tornadoes. Three tornadoes were spawned from the thunderstorms. However, since two of the tornadoes crossed a county border, five tornadoes will officially be recorded with this event. This is considered an unusual event since tornadoes in late October in Southeast Michigan are extremely rare. Following the passage of the cold front early on the morning of the 25th, winds gusting as high as 45 MPH affected the region and dropped temperatures 20 to 30 degrees.
