Severe thunderstorms developed ahead of an upper level trough which was digging into the Great Lakes.

The tornado appeared to first touch down along Indiana State Route|38 approximately 0.15 mile west of the intersection with Round Barn|Road. A barn here sustained substantial damage when a section of its|roof measuring approximately 45 feet by 20 feet was removed. The|wood and metal material was briefly lifted then dropped immediately|northeast of the structure. There were also several broken tree|limbs and slate roofing material from a smaller barn strewn across|this same property from southwest to northeast. All of the debris|here was confined to a narrow path no more than 75 feet wide, with|no divergent patterns noted.||The tornado next moved across an open field before crossing Round|Barn Road approximately 0.20 mile north of the intersection with|Indiana State Route 38. The circulation oriented corn debris from|the previous growing season in a parallel to slightly convergent|pattern approximately 40 feet wide on both sides of Round Barn Road.|This corridor was rather dramatic, with a quick transition to the|unaffected field debris occurring over just a few feet along the|edges of the path. Nearby residents related that a video posted to|several media outlets showing the tornado was actually recorded|looking south on Round Barn Road when the circulation crossed this|location.||The next area of damage occurred immediately east of Round Barn Road|as the tornado tracked northeast toward Tingler Road. The|circulation appeared to strengthen and widen at this point, with the|greatest intensity and path width likely realized. At least 6|residences appeared to sustain some level of property damage here|with many trees and limbs 10 to 14 inches in diameter broken, lifted|and carried by the wind as much as 100 yards. There were also|several locations in this damage area where debris was oriented at|opposing angles to storm motion, as well as in semi-circular|patterns. Additionally, grass and leaf spatter was observed on the|east-facing wall of large shed near the open field. Mainly minor|structural damage occurred to the homes in this area, with shingles|and siding most affected. One small shed approximately 12 feet|square was completely destroyed, though it did not appear to be|firmly anchored to the ground.||At least 3 residents in this area observed the tornado as it tracked|through both their yards and the open field immediately to the east.|They also described the rapid shift of wind direction counter-|clockwise from the northeast through to the southwest as the|circulation approached and passed by their location. One of these|residents also related how they were literally pinned briefly|against a door as the wind associated with the tornado passed|through their home, knocking down a number of objects inside the|home.||The tornado continued northeast across an open field to a crossing|with Tingler Road approximately 0.20 mile east of the intersection|with Round Barn Road. Much like the field to the southwest of this|location, plant material from the previous growing season was|observed to be oriented in a parallel to slightly convergent pattern|along the approximately 100 yard wide path. Debris from the Round|Barn Road residences was also visible in random spots along this|path. The tornado once again passed into an open field on the north|side of Tingler Road. A large tree in this field approximately 0.4|mile north of Tingler Road was snapped, though its health was|unclear as a close inspection wasn`t possible due to limited access.||The circulation continued on the ground to US Route 35 approximately|one-half mile north of the intersection with Tingler Road. Several|properties on both sides of the road sustained a number of broken|tree limbs and minor structural damage to shingles and wooden|fences. Broken tree branches appeared to be 6 inches in diameter or|less. The tornado appeared to finally lift immediately east of US|Route 35 and south of the town of Webster, where the last tree|damage was visible.

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

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

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 19:44 UTC.

3 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.
