EF0 tornado, Olney, Illinois, March 15, 2026
This EF0 tornado ran 2.0 miles across Richland County on March 15, 2026, touching down at 8:05 PM CDT and reaching 40 yards wide. It killed nobody.
Preliminary. This is NWS ILX's damage survey, filed in the Damage Assessment Toolkit as Olney 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 mphthis tornado
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mph
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 Weather Service recorded
A strong low pressure system (987 mb) moved across Illinois during the afternoon of Sunday, March 15, 2026. The environment was characterized by high shear and weak instability. A line of storms swept across the state, producing scattered wind damage and eight tornadoes within the NWS Central Illinois coverage area. The tornadoes occurred southeast of the I-72 corridor and all were rated EF-0 or EF-1. No injuries occurred.
The tornado began just west of Olney and was sighted at the intersection of west Main Street and west Elms Street. The tornado proceeded through town, causing areas of tree and fencing damage. The tornado dissipated on the east side of town. It was rated EF-0, with a path length of just over two miles and a duration of two minutes.

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 Marginal Risk. The outlook in force was issued at 00:43 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.
Sources
NWS Damage Assessment Toolkit, the record the survey teams file from the damage, and NOAA Storm Prediction Center storm reports. Neither is the official database for 2026, which SPC publishes in the spring of 2027.
