On the evening of August 26, 2016 a line of strong storms formed in northeastern Kansas, and then moved into northwestern Missouri. Embedded within the line of storms was a supercell, which formed earlier in the evening. This supercell produced some isolated strong wind gusts, most likely associated with the RFD. It also went on to produce a weak tornado that lasted 10 minutes and traveled 4 miles. The only damage associated with this tornado was a few tree limbs and power lines. Later in the evening storms continued to train over northeast Kansas and northwest Missouri, which brought impressive flooding to portions of the Kansas City metro area late in the evening.

Emergency Management reported a funnel three-quarters of the way to the surface, with dust whirls and an occasional power flash. A video sent to the office via Twitter showed what appears to be a weak tornado with a truncated funnel and dust whirls at the surface. Since the tornado did not have a continuous path and since it was relegated mostly to open fields the damage was minimized to tree limbs and a few power lines.

3 minutes of warning. NWS EAX issued a tornado warning for this county at 00:22 UTC, 3 minutes before the tornado touched down, in force until 00:45 UTC.

The county was under a tornado watch, issued at 23:13 UTC and running to 03:00 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 Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:58 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.
