EF1 tornado, White City to Irving, Illinois, March 15, 2026

From White City to Irving, this EF1 tornado ran 6.3 miles across Macoupin and Montgomery counties on March 15, 2026, touching down at 5:29 PM CDT and reaching 300 yards wide. It killed nobody.

Preliminary. This is NWS LSX's damage survey, filed in the Damage Assessment Toolkit as Mount Olive 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.

The damage survey

61 damage points were recorded along this path by NWS LSX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 100 mph.

  • Poles were snapped but already replaced
  • Lofted into street but cleaned up
  • Trunk snapped but not visible

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

During the afternoon and evening of March 15th, a QLCS moved through southern and south-central Illinois. Stronger segments of the QLCS produced wind damage across the region. The QLCS ended up producing 8 tornadoes while it passed through the region.

A tornado touched down just west of the Staunton Reservoir where it damaged trees along Bono Road. The tornado then travelled northeast, causing minor damage to the roofs of a few structures before directly hitting Mount Olive. In Mount Olive, the tornado damaged mostly trees, but the roof of a business was impacted as well. The tornado weakened as it exited town and approached Montgomery County.

The tornado moved into Montgomery County from Macoupin County, where it caused minor damage to a home on W County Line Road. The tornado then took on a near due northerly track as it occluded and caused minor tree damage before it dissipated completely just north of Saint Johns Ave.

A tornado touched down near Niemanville Trail and trekked northeast, producing mostly tree damage in its path. At its strongest the tornado was able to produce minor damage to farm outbuildings and break wooden power poles. The tornado dissipated just east of East 8th Road.

A brief tornado touched down on the Hillsboro Country Club where it produced minor damage to a home. The tornado then travelled northeast where it damaged trees, an outbuilding, and electrical poles. The tornado dissipated just north of White Ave west of Irving.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

The warnings

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

The county was under a tornado watch, issued at 18:33 UTC and running to 23:26 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 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 19:57 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

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.
