EF1 tornado, Tackner to Whitakerville, Missouri, April 17, 2026
From Tackner to Whitakerville, this EF1 tornado ran 5.9 miles across Benton County on April 17, 2026, touching down at 7:19 PM CDT. It killed nobody.
Preliminary. This is NWS SGF's damage survey, filed in the Damage Assessment Toolkit as Warsaw. 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
An NWS survey concluded an EF1 tornado touched down southwest of Warsaw, crossing the lake, and tracking just east of Highway 65. The tornado flipped several mobile homes resting on blocks, damaged signs and roofing associated with stores along Highway 65, and created a pattern of tree damage including many uprooted or snapped, surveyed through in-person and Sentinel-2 satellite surveys.

The damage survey
24 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 100 mph.
- Roofs and signs damaged with debris blown east and north
- Numerous mobile homes in a storage facility overturned
- Numerous trees uprooted, some snapped, falling north, east and south
- Windows broken at the visitor center as well

What the Weather Service recorded
A vigorous low-pressure system and cold front pushed through the Plains and the Ozarks, interacting with a warm, moist air mass as a strong upper-level trough and a veered wind profile created high wind shear and instability. This set the stage for supercellular development that evolved into bowing line segments. This setup brought destructive straight-line wind gusts of 60-70 mph, with isolated gusts reaching up to 75 mph. Hail up to 2 inches occurred and 5 tornadoes touched down in Benton and Morgan Counties.
An National Weather Service survey concluded an EF1 tornado touched down southwest of Warsaw, crossing the lake, and tracking just east of Highway 65. The tornado flipped several mobile homes resting on blocks, damaged signs and roofing associated with stores along Highway 65, and created a pattern of tree damage including many uprooted or snapped, surveyed through in-person and Sentinel-2 satellite surveys. The tornado tracked for a little over 6 miles with a path width of 200 yards and maximum wind speeds of 90mph.
A National Weather Service survey concluded an EF0 tornado caused damage to a building on 83 and Highway MM southeast of Warsaw. This tornado is also damaged multiple trees in the area which was confirmed via Sentinel-2 satellite data analysis. The tornado had maximum winds of 80 mph and was on the ground for about 0.4miles with a width of 200 yards.

The warnings
38 minutes of warning. NWS SGF issued a tornado warning for this county at 23:41 UTC, 38 minutes before the tornado touched down, in force until 00:30 UTC.
The county was under a tornado watch, issued at 22:29 UTC and running to 02:00 UTC.

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 0.05 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 19:53 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.

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.
