Two EF-0 tornadoes struck portions of Jackson county on July 26th resulting in some damage mostly to trees and some crops. Severe storms also produced damaging wind gusts.

A line of thunderstorms developed ahead of a frontal boundary and moved across Lake Michigan during the morning hours of July 26, 2023. These thunderstorms would eventually track across the state into a very warm and unstable environment. The southern end of the line of storms is where the strongest winds associated with the line would develop and moved across the lower portions of southeast Michigan during the afternoon between 2 PM and 5 PM. A swath of widespread 60-70 mph wind gusts with locally higher gusts resulted in numerous downed trees, downed powerlines, and around 165,000 power outages in southeast Michigan. The Ann Arbor and the Detroit/Grosse Pointe areas were hit the hardest.

A brief EF-0 tornado occurred southeast of Stockbridge. It touched down near Orchard Creek east of Fitchburg road and south of Baseline road. Several dozen large trees were impacted with several uprooted trees along the path. Several homes on Musbach road had minor roof damage or damage from tree debris. The tornado lifted near Dewey road.

A brief EF-0 tornado occurred just north of Whitehead Lake and south of Territorial road in northeast Jackson county. It moved east northeast and lifted just northeast of Leeke road and north of Bowdish road. Intermitted damage was foudn along the path primarily to trees and crops. One business along the path sustained some minor structural damage that included roof damage and siding damage to an outbuilding.

A weak tornado with maximum winds of 70 mph tracked east-northeast from northeast Jackson County and briefly crossed into Livingston County before dissipating just northeast of Leeke Road and north of Bowdish Road. One business along the path sustained some minor structural damage that included roof damage and siding damage to an outbuilding.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Enhanced Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 16:09 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
