Walnut size hail, damaging wind and heavy rain top the list of Michigan weather events on this day in history. From the National Weather Service andStorm Prediction Center (SPC) archives here are the Michigan weather events that happened on July 29.
1852 – A severe thunderstorm struck Mackinac Island with hail the size of walnuts fell (1.5 inch). Almost every window was broken on one side of the Mission house Hotel.
1909 – A severe thunderstorm hit Ironwood in the early morning hours. Buildings were unroofed, windows smashed and trees uprooted throughout Ironwood and the surrounding area. This storm might have produced a tornado and it produced thousands of dollars in damage, but no deaths or serious injuries occurred. Heaviest losses were incurred by the Newport Mining Company in Ironwood. Three buildings were unroofed. The power plant had its 14 inch brick walls blown in from the storm. The plant sustained severe damage to the machinery as the west wall caved in. 60 feet of the south wall imploded bringing down the steel-trussed roof. The mine was forced to suspend underground mining operations for several days afterward. 200 feet of the dry house blew away and roof timbers 12 feet long were hurled several hundred feet from the site. One man at the mining company in the engine house said he jumped out of the window as the funnel descended on the building and when he came to earth again, he was sprawled out among the wreckage some 250 feet from the engine house. Another man ran out the front door and claimed he was picked up and carried to the company barn about 100 yards away.
1916 – Temperatures soared to record highs as a ten day heat wave reached its peak. The 102° at Lansing would tie the record for the hottest day ever there. Grand Rapids hit 103° as part of a record string of four consecutive days of 100° or higher. Even the Lake Michigan shore was baking, with Muskegon hitting 95°.
1999 – A severe thunderstorm produced a wind gust up to 86 mph in Bark River in the early morning. 6 inch trees were down along Highway US-41 at Rapid River. A 1 foot diameter tree was down across Kimberly Road in Norway.
2000 – Thunderstorms brought flash flooding to Detroit. Rain amounts were 2.92 inches of rain.

2006 – Thunderstorms produced heavy rainfall of 4 to 6 inches over much of western Gogebic County during the early morning hours. Minor street flooding was reported in the Bessemer, Wakefield and Marenisco areas as well as flooding on Bingham Creek near Lake Gogebic. An approaching cold front interacting with an extremely unstable airmass triggered a widespread outbreak of severe weather across west and central Upper Michigan from late afternoon on the 28th to just after sunrise on this day.
