EF0 tornado, Clay and Jackson counties, Missouri, June 13, 2026

This EF0 tornado ran 9.2 miles across Clay and Jackson counties on June 13, 2026, touching down at 8:34 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 Avondale. 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.

  1. EF065 to 85 mphthis tornado

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. 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.

  4. 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.

  5. EF4166 to 200 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. 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.

  7. 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

During the evening of Saturday June 13, 2026 a line of damaging thunderstorms moved across the Kansas City Metropolitan Area. At 8:33 PM CDT, a tornado formed on the leading edge of the line near Avondale, MO. The tornado produced sporadic tree damage near the Harrah's Casino before moving over the Missouri River. Sporadic tree damage was found near Birmingham, MO before the tornado crossed the Missouri River near MO-291 and produced substantial tree damage in LaBenite Park. The track could not be followed east of the park and no more damage was found further, so the tornado likely ended east of the park around 8:50 PM CDT. Thank you to Sugar Creek PD for their assistance with the damage survey.

The damage survey

36 damage points were recorded along this path by NWS EAX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 85 mph.

  • Branch driven into the ground.
  • Temporary fence knocked over to the northwest.
  • Tree debris thrown to the west.
  • Scattered small limbs and branches.

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

The forecast that day

The Storm Prediction Center had this point in a Enhanced Risk, with a 0.02 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 01:01 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.
