6 damage points were recorded along this path by NWS JAN, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 80 mph.

• A few trees snapped, several large branches broken
• Two sheds damaged, one with the roof off, the other roof and walls down. Debris blown to the north.

A significant severe weather event was expected on March 17th as a volatile airmass was in place across the region. Ample moisture, strong wind shear and a stout weather system moving through set the stage for significant severe weather. Storms developed during the afternoon and moved east. Some storms did produce large hail and some tornadoes. The primary hazard was from damaging winds as a squall line moved through the region during the late afternoon and evening.

An EF-0 tornado touched down near Carroll and Caney Church Roads. A few trees were blown down, and a couple of sheds were destroyed. Debris was blown across a field in a northward direction. The tornado moved to the northeast and crossed Chambliss and H Thompson Roads. On Chambliss Road, a home had most of the roof blown off, and a mobile home had a tree fall through half of it. The tornado dissipated just after crossing Thompson Road. Max estimated winds were 80 mph.

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

The county was under a tornado watch, issued at 16:41 UTC and running to 23:50 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 Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 21:37 UTC.

32 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.
