Record number

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

NWS ground survey along with public reports determined that an EF0 tornado with a 200 yard wide path initially touched down in a wooded area at the end of County Road H-522 to the southeast of Eminence. The tornado damaged a barn then both broke and uprooted trees as it crossed Highway H and along Highway NN to the Rocky Falls Shut In area off County Road NN-526.

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

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

• Eyewitness reported funnel cloud with swirling tree debris.
• Large limbs broken and laying west through east.
• Tree damaged with some uprooted. Debris fell east and north
• Trees broken and uprooted laying east.

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

A round of severe thunderstorms, a tornado and flash flooding occurred during the evening of June 21, lasting into the morning of June 22.

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.

The county was under a severe thunderstorm watch, issued at 22:41 UTC and running to 04:17 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 Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 01:12 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 St Louis radar (KLSX), 184 km away, was scanning. The volume nearest the touchdown began at 01:01 UTC.

43 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.
