EF1 tornado, Nyman to Villisca, Iowa, June 11, 2026

From Nyman to Villisca, this EF1 tornado ran 1.9 miles across Page County on June 11, 2026, touching down at 6:11 AM CDT and reaching 50 yards wide. It killed nobody.

Preliminary. This is NWS OAX's damage survey, filed in the Damage Assessment Toolkit as South of Villisca Tornado. 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 mph

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

  2. EF186 to 110 mphthis tornado

    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

A brief tornado developed south of Villisca at approximately 6:11 AM. The tornado would track along 110th St between V Ave and Willow Ave before dissipating near the county line at 6:13 AM. Along the tornado's path, trees were damaged, a farm outbuilding lost part of the roof and wall, and a carport was destroyed. The tornado had estimated wind speeds of 90 mph earning a rating of EF1. The maximum estimated width of the tornado was approximately 50 yards.

The damage survey

40 damage points were recorded along this path by NWS OAX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 105 mph.

  • One tree uprooted, other large limbs down.
  • about 10 pine tree trunks snapped
  • Two trees uprooted and numerous other large limbs down. Minor damage to homes, siding and roof.
  • Trunk snapped, large out building collapse, power lines down

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

What the Weather Service recorded

On the morning of June 11, 2026, severe thunderstorms pushing across southeast Nebraska into southwest Iowa produced tornadoes, large hail, damaging wind gusts, and flash flooding. The synoptic setup for the event featured broad upper-level troughing over the Northern High Plains, with a strong shortwave trough pushing into eastern Nebraska early in the day. This feature provided upper-level dynamic support for the amplification of the low-level jet (LLJ) alongside subsequent low-level warm air and moisture advection. This ultimately generated the forcing necessary for storm development, which began around 1:00 AM to 2:00 AM local time over central Nebraska.||As the LLJ strengthened overnight, a surface frontal boundary began to advance northward into southeast Nebraska. Isentropic upglide to the north of the surface front led to destabilization above the boundary layer. This elevated instability, combined with 40 to 55 knots of 1-3 km bulk shear along the nose of the LLJ, led to the organization of a strong mesoscale convective system (MCS) that tracked across eastern Nebraska and into southwest Iowa.||As the storms initally pushed into eastern Nebraska, the first report of large hail���measuring up to 1.25 inches in diameter���surfacing was reported in Seward County at 2:19 AM CST. By 3:00 AM CST, the system intensified and progressed eastward into Lancaster County, producing an initial 74 mph wind gust near Valparaiso and dropping hail up to 2.50 inches in diameter. As the storms tracked directly through Lancaster County between 3:11 AM and 4:01 AM CST, they generated widespread wind damage, snapping trees and downing powerlines. One notable incident occurred at 3:46 AM CST when an estimated 10-inch diameter tree limb fell onto a home, resulting in an injury. The system then continued east toward the Missouri River, pushing into Cass County around 4:04 AM CST where it immediately began causing structural damage and dropped its first reported tornadoes shortly after 4:10 AM CST.||Crossing into southwest Iowa around 4:30 AM CST, the system's focus shifted heavily toward pockets of damaging wind gusts, brief tornadoes and flash flooding. Tornadoes were reported consecutively across Fremont, Mills, Page, and Montgomery counties between 4:29 AM CST and 5:11 AM CST. As the morning progressed, intense straight-line winds up to 90 mph continued in a swatch across eastern Page and Montgomery counties in Iowa, particularly between Coburg and Villisca, IA. By 5:26 AM CST, the severe wind and hail threats began to transition into a significant flash flood event. Heavy downpours���including a staggering 6 inches of rain reported in Sidney, Iowa by 6:00 AM CST���led to flooded creeks, residential yards, and submerged roadways across Page and Fremont counties as the storms finally pushed out of the area.

At approximately 4:58 AM CST, a tornado developed just east of Coburg, Iowa, near 105th Street and K Avenue, and moved east-southeast. The tornado produced sporadic tree damage with an estimated wind speeds of 70 mph. The tornado would then track east, parallel to 110th St. Along the path, trees and farm outbuildings received damage. Max wind speeds were estimated at low-end EF1 intensity of 90 mph. The tornado would dissipate at approximately 5:08 AM CST near 110th St and R Ave. The estimated maximum width was approximately 100 yards.

A brief tornado developed south of Villisca at approximately 5:11 AM CST. The tornado would track along 110th St between V Ave and Willow Ave before dissipating near the county line at 5:13 AM CST. Along the tornado's path, trees were damaged, a farm outbuilding lost part of the roof and wall, and a carport was destroyed. The tornado had estimated wind speeds of 90 mph earning a rating of EF1. The maximum estimated width of the tornado was approximately 50 yards.

The forecast that day

The Storm Prediction Center had this point in a Marginal Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 06:19 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.
