A cold front triggered a few late evening severe thunderstorms between the I-69 and M-59 corridors. Damaging winds and a weak tornado near Lake Fenton occurred.

An NWS storm survey confirmed a weak tornado developed over or along the shoreline of eastern Lake Fenton during the late evening of July 11th. The tornado tracked east-southeast for 7.5 miles before lifting 3 miles east-southeast of Holly/just west of I-75 in northern Oakland County. The first indication of damage occurred on Pine Street near Lake Fenton where large limbs fell on a home, which took out a second-story dormer and a portion of the roof. Tree damage was sparse and sporadic along the path, mainly consisting of tree limbs and leaves down. The weak tornado crossed into northwest Oakland County just southwest of Oyster Lake, and continued tracking southeast for an additional 6.1 miles. The peak damage was observed in the backyard of a home on Addis Road in Holly. About a dozen trees suffered significant damage. The home also lost a few vinyl siding panels and a pergola was damaged. A barn farther down the road lost some metal roofing.

0 minutes of warning. NWS DTX issued a tornado warning for this county at 03:33 UTC, 0 minutes before the tornado touched down, in force until 03:42 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 Marginal Risk. The outlook in force was issued at 00:52 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Detroit radar (KDTX), 20 km away, was scanning. The volume nearest the touchdown began at 03:32 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.
