EF0 tornado, Coin to College Spgs, Iowa, April 23, 2026

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.

None yet. SPC numbers 2026 in the spring of 2027.

Two spotter reports confirmed a funnel with rotating dust at ground level with minor tree damage at one location. The track was mainly over open fields.

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

3 damage points were recorded along this path by NWS OAX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EFU. The highest wind the damage implies is 70 mph.

A broken line of strong to severe thunderstorms impacted eastern Nebraska and southwest Iowa on April 23rd, 2026. The system was driven by a broad upper-level trough located over the western third of the United States, as additional shortwave energy rounded the ridge and pushed into the central Plains. In response to these features, strong lee troughing developed across the Great Plains. Southerly winds rapidly drew rich Gulf moisture northward, pushing dewpoints into the 60s. Surface observations showed a front draped from south-central Nebraska into northeast Nebraska and northwest Iowa, which slowly progressed eastward through the afternoon. This system brought strong winds throughout the vertical column, increasing deep-layer shear. This enhanced shear combined with steep lapse rates to provide a highly favorable environment for severe thunderstorms. A weak cap in place during the afternoon initially limited development until a few convective updrafts managed to punch through. The initial storms were isolated, posing a primary threat for large hail and tornadoes, particularly for those that interacted with the frontal boundary. Through the late afternoon and into the evening, convective development became much more widespread along the front as it slowly pushed eastward, bringing reports of hail, damaging wind gusts, and tornadoes. ||Numerous hail reports were received throughout the event. As storms matured, a southwest-to-northeast oriented broken line of supercells formed, extending generally from Lincoln, NE, through Omaha, NE, and into Little Sioux, IA. Wind gusts were measured up to 68 mph, and a tornado was confirmed near Little Sioux as a supercell approached the frontal boundary and underwent a storm merger. Within this corridor, hail ranging from 1 to 1.75 inches in diameter was widely reported. Further south, an additional strong supercell developed near Fairbury, NE. This storm tracked east-northeast, gradually growing upscale as it advanced. As the cell progressed, it produced hail up to 2 inches in diameter and spawned three brief tornadoes in southwest Iowa.

Two spotter reports confirmed a funnel with rotating dust at ground level with minor tree damage at one location. The track was mainly over open fields. Maximum wind speeds were estimated at 70 mph.

9 minutes of warning. NWS OAX issued a tornado warning for this county at 23:08 UTC, 9 minutes before the tornado touched down, in force until 23:48 UTC.

The county was under a tornado watch, issued at 17:02 UTC and running to 00:00 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 Storm Prediction Center had this point in a Slight 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 19:45 UTC.

19 more have been surveyed in the United States that day, so far.

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.
