EF1 tornado, McLean County, Illinois, April 17, 2026
This EF1 tornado ran 33.8 miles across McLean County on April 17, 2026, touching down at 8:54 PM CDT and reaching 150 yards wide. It killed nobody, and did $300 of property damage.
Preliminary. This is NWS ILX's damage survey, filed in the Damage Assessment Toolkit as Downs-Ellsworth 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.
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 tornado touched down about 2.5 miles southeast of Funks Grove where it produced some tree damage along E 400 North Rd. It progressed northeast crossing Hwy 51 just south of Randolph, causing damage to numerous trees along the way. As it headed toward Downs, it caused EF-1 damage to a home several large trees, with estimated wind speeds of 100 mph. As the tornado moved northeast toward Ellsworth, it caused more tree damage and some home damage, with wind speeds up to 100 mph. The remainder of the tornado path were through countryside areas, with tree damage the primary impacts. The tornado dissipated about 1.5 miles from the McLean County line along E 1700 North Rd.

The damage survey
241 damage points were recorded along this path by NWS ILX and NWS LOT, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 110 mph.
- Insulation blown to east from building.
- Looks like it split and went two directions.
- Debris blown east across street into field.
- Several large trees downed or uprooted on the east side of Clearwater Park. Multiple trees were snapped at the base. Some of the trees fell onto park equipment, resulting in damage to picnic tables and trash cans.
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 0.05 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 00:59 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.
