42 damage points were recorded along this path by NWS MPX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF2. The highest wind the damage implies is 125 mph.

• Lots of trees down along 179th, no structure damage. Likely continuation of Watkins tor
• Corn flattened on both sides of road with some tree damage in cluster in the background of photo
• Possible end of Watkins tor
• Tree pictured came from house across the street where a trampoline was tossed as well

The morning of Monday, July 11th, two waves of thunderstorms moved across west central and central Minnesota. Very heavy rainfall and isolated hail occurred with the main area of storms. But these storms also produced a wide area of one half to two inches of rain by sunrise. ||The morning two events set the stage for flooding in central Minnesota as several additional waves of thunderstorms developed during the afternoon, and into the evening. By Tuesday morning, a wide area of three to six inches of rain fell from north of St. Cloud to Milaca and Mora. The highest totals were across northern Kanabec County where locally six to eight inches fell based on radar estimation. The Rum, Snake and Knife rivers spilled out of their banks and caused significant and widespread flooding. ||A secondary point related to this flooding event was that according to the Minnesota State Climatology Office, this storm, which continued into the morning hours of July 12th, was the largest mega-rain event since the Duluth flood of June 19-20, 2012. A mega-rain event is classified as a six-inch rainfall that covers at least a 1000 square miles, with a central core value of at least 8 inches. ||The secondary wave in the morning, weakened by the early afternoon. An isolated thunderstorms developed near Litchfield where an outflow boundary held from the previous morning storms. These storms moved slowly northward and produced three tornadoes along this boundary. The first tornado occurred near Litchfield, the second near Watkins, and the third north of Watkins. ||The tornado near Litchfield was rated an EF-2 with peak winds of 115 mph. It had a maximum width of 100 yards and traveled approximately 3.1 miles. The tornado caused a lot of tree damage, though three single family homes received significant roof damage, and a double wide manufactured home, and garage were flipped and rolled. Another garage and shed were destroyed near Highway 12 on the north side of town.||The tornado near Watkins was also rated an EF-2 with peak winds of 125 mph. It had a maximum width of 400 yards and traveled approximately 2.1 miles. One injury occurred with this tornado. The first significant damage was to a business along Highway 55 on the south side of town. The tornado then tracked across the highway and passed through the St. Anthony Cemetery before passing through the center of Watkins doing damage to structures and many trees. The most significant damage occurred between Stearns Ave and Meeker Ave where several homes had significant roof damage, and had detached sheds, and garages destroyed. The tornado exited the town and did further tree damage at a farmstead outside of town before lifting shortly thereafter.||The tornado north of Watkins was rated an EF-1 with peak winds of 105 mph. It had a maximum width of 250 yards and traveled approximately 4.2 miles. This tornado was spawned by the same storm that moved through Watkins. Multiple chaser videos showed the Watkins tornado lifted off the ground as it became occluded, with this tornadoes touchdown point made visible by the presence of corn laid down in the field south of the first homestead hit. This was about two-thirds of mile north- northeast of where the Watkins tornado lifted. At the first farmstead hit, two open air cattle sheds where completely destroyed, along with a metal storage shed and two mostly empty grain bins. There were two cattle killed at this location as well. This storm destroyed more outbuildings at a farmstead along 160th street, with the rest of the damage along the path of the tornado being corn laid flat and tree damage.

The tornado north of Watkins in Stearns County was rated an EF-1 with peak winds of 105 mph. It had a maximum width of 250 yards and traveled approximately 4.0 miles. This tornado was spawned by the same storm that moved through Watkins. Multiple chaser videos showed the Watkins tornado lifted off the ground as the parent storm became occluded, and a new tornado developed shortly thereafter, with its touchdown point made visible by the presence of corn laid down in a field south of the first homestead hit. This was about two-thirds of a mile north-northeast of where the Watkins tornado lifted. At the first farmstead to be hit, two open air cattle sheds were completely destroyed, along with a metal storage shed and two mostly empty grain bins.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

12 minutes of warning. NWS MPX issued a tornado warning for this county at 22:40 UTC, 12 minutes before the tornado touched down, in force until 23:15 UTC.

The county was under a tornado watch, issued at 22:31 UTC and running to 03:00 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 Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:59 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 Minneapolis radar (KMPX), 84 km away, was scanning. The volume nearest the touchdown began at 22:50 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.
