EF1 tornado, Linn County, Missouri, May 16, 2026
This EF1 tornado ran 2.6 miles across Linn County on May 16, 2026, touching down at 6:28 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 Linn County MO Tornado 2. 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 same severe supercell thunderstorm that resulted in the first Linn County tornado, resulted in a second north and east of Shafter, MO. This tornado began at 6:28 PM CDT near the intersection of Daisy and Clark Rd. It continued southeast resulting in EF-1 damage to several farm outbuildings, including a wellbuilt barn. It picked up two empty grain bins and distributed them east-northeast across open pasture. Damage was noted in the tree-lines beyond the property to the southeast. The track was picked back up along highway DD, where wideswaths of EF-1 and EF-0 tree damage were noted along both sides of the highway. The path ends about a half mile before the intersection with Highway Y around 6:32 PM CDT.

The damage survey
28 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 110 mph.
- Swath of trees topped south of DD HWY
- Numerous trunks snapped on both sides of HWY DD
- Complete swath of wooded area north and along highway DD damaged. Snapped trunks and twisted tree tops.
- Two wood poles broken along highway DD.

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.
