EF1 tornado, Pearl City, Illinois, April 14, 2026

This EF1 tornado ran 5.1 miles across Stephenson County on April 14, 2026, touching down at 7:39 PM CDT and reaching 100 yards wide. It killed nobody.

Preliminary. This is NWS DVN's damage survey, filed in the Damage Assessment Toolkit as Pearl City. 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 tornado formed briefly in the occlusion of an RFD northwest of Pearl City. It heavily damaged and destroyed several farm outbuildings, lifted a large farm wagon into an outbuilding, damaging the roof and side. The tornado also snapped several tree trunks and tree damage. Power poles were also snapped as the tornado crossed Illinois Highway 73 before lifting shortly thereafter. The tornado caused EF-1 damage with maximum estimated winds of 105 mph.

What the Weather Service recorded

Significant severe storms on the afternoon and evening of April 14th brought numerous reports of large hail, damaging wind, and multiple tornadoes. The U.S. Hwy 20 corridor saw a long lived supercell that producing large hail (up to baseball size), damaging wind (88 mph gust at the Dubuque Airport), and several tornadoes. Additional storms developed further south between I-80 and Hwy 20 that brought large hail and a photogenic tornado near Onslow, IA. ||More storms quickly followed overnight and again on the next day, April 15th, bringing heavy rain, large hail, and isolated wind damage. Rainfall amounts over 1.5 were common north of I-80, with the highest totals over 3.5 seen in northwest IL. This caused a mudslide on Hwy 84 in Carroll County closing the road for an extended period of time.

A tornado formed briefly in the occlusion of an rear flank downdraft northwest of Pearl City. It heavily damaged and destroyed several farm outbuildings, lifted a large farm wagon into an outbuilding, damaging the roof and side. The tornado also snapped several tree trunks and tree damage. Power poles were also snapped as the tornado crossed Illinois Highway 73 before lifting shortly thereafter. The tornado caused EF-1 damage with maximum estimated winds of 105 mph.

The warnings

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

The county was under a tornado watch, issued at 19:35 UTC and running to 03:00 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 Enhanced Risk, with a 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 19:36 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.
