10 damage points were recorded along this path by NWS LZK, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 90 mph.

• Dead/diseased trees uprooted.
• New power pole, trees snapped in the distance in a field, small outbuilding destroyed.
• Outbuilding debris blown high into tree tops.
• Large outbuilding blown off of foundation, but was only sitting on cinder blocks and nearby very light/vulnerable structures appear undamaged. One outbuilding had it’s time roof torn off and blown downwind.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

A line of strong to severe storms developed ahead of the front, with the most robust storms closest to the Missouri border after 500 pm CST. One storm in particular went from southeast Boone County into southern Marion County and northwest Baxter County. The storm had strong rotation at times and it headed quickly to the northeast at 40 to 50 mph. There was plenty of chaos in the path of the storm, and no doubt that one or more tornadoes were in play.||A house was damaged east of Everton (Boone County), and power lines were downed. Between Pyatt and Bruno (both in Marion County), several homes were damaged or destroyed with an injury reported. A school was also affected. A tree fell through a house west of Mountain Home (Baxter County).||In the end, two tornadoes (rated EF1/EF2) were spawned in a three county area. Three more weak tornadoes (all rated EF1) were confirmed with separate storms from five miles north of Hector (Pope County) to six miles west-southwest of Rupert (Van Buren County), and from four miles northeast of Evening Shade to four miles north of Poughkeepsie (both in Sharp County). These tornadoes toppled trees and hit a couple of barns and outbuildings.||This event did not feature a lot of rain, and there was only 0.01 inch measured at Little Rock (Pulaski County) on the 19th. But, this was enough to make it eleven consecutive days with measurable precipitation. It was one day away from tying the all-time record of twelve days in a row. A trace of rain on the 20th ended the streak.

For the majority of the tornado's path, large trees and power poles and power lines were the most common damage indicators. The majority of the structural damage caused by the tornado was observed at the Mashburn farm where there was substantial damage to outbuildings, including one outbuilding that slid off of its foundation. There was minor damage to a residence on the farm as well, and extensive tree damage throughout the property.

38 minutes of warning. NWS LZK issued a tornado warning for this county at 02:29 UTC, 38 minutes before the tornado touched down, in force until 03:15 UTC.

The county was under a tornado watch, issued at 02:50 UTC and running to 04:53 UTC.

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 Enhanced Risk, with a 0.10 chance of a tornado within 25 miles. The outlook in force was issued at 00:51 UTC.

11 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.
