None yet. SPC numbers 2026 in the spring of 2027.

Brief tornado in this location per damage survey, RaXPol radar data, and chaser video. Damage was limited to a couple overturned pivots and an empty grain bin and broken tree branches at a farmstead.

Written by NWS GID in the NWS Damage Assessment Toolkit. A survey is revised as better evidence arrives.

52 damage points were recorded along this path by NWS GID, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF3. The highest wind the damage implies is 160 mph.

• Start point based on eyewitnesses
• Approximate touch down point in field per chaser video analysis.
• Loss of roof and walls of shed
• Large tree uprooted. Facing ESE

16 minutes of warning. NWS GID issued a tornado warning for this county at 22:07 UTC, 16 minutes before the tornado touched down, in force until 23:00 UTC.

The county was under a tornado watch, issued at 20:16 UTC and running to 00:32 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 Enhanced 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 20:02 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 Grand Island radar (KUEX), 100 km away, was scanning. The volume nearest the touchdown began at 22:24 UTC.

47 more have been surveyed in the United States that day, so far.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. A survey can be revised, so the rating, the path and the casualties can all still change.

NWS Damage Assessment Toolkit, the record the survey teams file from the damage, and NOAA Storm Prediction Center storm reports. Neither is the official database for 2026, which SPC publishes in the spring of 2027.
