Showers and thunderstorms developed across central and east-central Wisconsin during the late morning and afternoon hours, producing funnel clouds and four tornadoes.A slow moving tornado that touched down about 4 miles south of Marshfield (Wood co.) tore siding from a garage, broke windows, destroyed a playhouse and a dog house, and blew two 50 pound barrels 200 yards away.A tornado briefly touched down west of Oshkosh (Winnebago co.) but no damage was reported. Two other tornadoes that touched down over Lake Winnebago were viewed by numerous participants of a fishing tournament that was taking place on the lake. One of these tornadoes touched down about 5 miles east of Oshkosh (Winnebago co.) and the other touched down about 4 miles west of Brothertown (Calumet co.).

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

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 General Thunderstorms Risk. The outlook in force was issued at 16:07 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 Green Bay radar (KGRB), 71 km away, was scanning. The volume nearest the touchdown began at 17:37 UTC.

9 more were confirmed in the United States that day.

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.
