A brief EF-0 tornado with winds to 80 mph touched down just on the west side of the Cal Sag Channel and tracked eastward across portions of Alsip. This tornado impacted areas roughly between W 120th Pl and W 121st St. Most of the damage consisted of uprooted or snapped trees, along with some downed power poles and lines. The total path length was approximately 2.5 miles long, with a max width of 175 yards.

5 damage points were recorded along this path by NWS LOT, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 80 mph.

A line of severe thunderstorms that would eventually become a derecho, produced widespread wind damage across much of northeast Illinois during the afternoon of June 10th. Two brief tornadoes also occurred.

A tornado with estimated peak winds of 80 mph touched down just east of Interstate 294 and snapped and uprooted trees between W 120th Pl and W 121st Street. Utility poles and power lines were also blown down. The tornado continued east crossing Route 50 and ended between railroad tracks and Kostner Avenue.

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

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 severe thunderstorm watch, issued at 19:40 UTC and running to 22:12 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 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 19:59 UTC.

23 more have been surveyed in the United States that day, so far.

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.

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.
