EF1 tornado, Saybrook, Illinois, December 28, 2025

This EF1 tornado ran 0.9 miles across McLean County on December 28, 2025, touching down at 3:24 PM CST and reaching 30 yards wide. It killed nobody.

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

2 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 90 mph.

  • West-facing portion of metal roof peeled eastward.
  • Outbuilding was destroyed and tossed toward the northeast. Images from WCIA TV media.

What the Weather Service recorded

The airmass continued to destabilize across central Illinois during the afternoon of December 28th as high temperatures reached record values in the upper 60s to around 70 degrees and dewpoints hovered in the lower to middle 60s. Thanks to the high degree of instability and shear, a line of thunderstorms rapidly formed along an advancing cold front near the I-55 corridor by early afternoon. The storms then pushed eastward, producing 3 tornadoes and scattered damaging winds eastward to the Indiana border. The most significant tornado was rated EF-2 and caused considerable property damage just south of Decatur in Macon County.

A tornado touched down about 3 miles east-southeast of Saybrook at 3:24 PM CST. The tornado destroyed a large outbuilding, throwing the debris to the east-northeast. It then quickly dissipated before reaching the Ford County line at 3:25 PM CST.

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

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. The outlook in force was issued at 19:46 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. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
