EF1 tornado, Daviess County, Missouri, June 10, 2026

Name: EF1 tornado, Daviess County, Missouri, June 10, 2026
Start: 2026-06-10T21:25:00.000Z
End: 2026-06-10T21:39:00.000Z
Location: Daviess County, Missouri

This EF1 tornado ran 10.5 miles across Daviess County on June 10, 2026, touching down at 4:25 PM CDT and reaching 200 yards wide. It killed nobody.

Preliminary. This is NWS EAX's damage survey, filed in the Damage Assessment Toolkit as Jameson. The rating, the path and the casualties are the survey's and can change while it is revised. The Storm Prediction Center compiles the official record of 2026 from these surveys and publishes it in the spring of 2027; this page moves to that tornado's permanent address when it does.

The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

EF065 to 85 mph
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mphthis tornado
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
EF2111 to 135 mph
Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.
EF3136 to 165 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
EF5over 200 mph
Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.
Unrated
The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the survey found

The third tornado, an EF-1, from the Dekalb/Daviess County supercell began just southeast of Jameson near Highway 13, destroying a pole barn along 235th Street. The tornado tracked northeast and caused extensive damage to several trees on a property near 250th and Route P. The path continued to the east-northeast, causing tree damage before ending just before the Grundy County line between Jameson and Trenton. The timing of this tornado was tied to spotter reports, as a second supercell traversed the same area about 30 minutes later. However, spotter reports clearly tied this to the leading supercell.

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

The damage survey

19 damage points were recorded along this path by NWS EAX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 100 mph.

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 forecast that day

The Storm Prediction Center had this point in a Enhanced Risk, with a 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 19:59 UTC.

What this means

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.
