A National Weather Service ground survey determined that an EF-1 tornado with estimated peak winds of 95 mph occurred a mile southwest of Mount Zion in Douglas County, lasting approximately 2 minutes and traveling a half mile. The tornado produced a 75 yard wide path of tree damage consisting of snapped trunks, uprooted trees, and large branches thrown around. Track extensions are still possible with additional satellite data analysis.

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

6 damage points were recorded along this path by NWS SGF, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 93 mph.

• Very narrow path of shredded trees. Trunks snapped about a third of the way up.
• 50 to 75 yard wide path of tree branches thrown around
• Visible extent of narrow tree damage path.
• Visible extent of narrow tree damage path. End point.

Several rounds of thunderstorms occurred during the period of June 25th and June 27th as a frontal boundary remained near the area. Some areas received 3-6 inches of rainfall over a short period of time. Thunderstorms produced a few tornadoes on the evening of June 26th.

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. One was issued for the county at another hour that day.

The county was under a severe thunderstorm watch, issued at 22:58 UTC and running to 02:51 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 20:00 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 Springfield radar (KSGF), 69 km away, was scanning. The volume nearest the touchdown began at 23:04 UTC.

4 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.
