Record number

None yet. SPC numbers 2026 in the spring of 2027.

4 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 107 mph.

Multiple rounds of severe thunderstorms passed through the region for nearly the entirety of April 27th. The afternoon round was expected to be the most volatile, with an environment primed for high-end severe weather reflected by an areawide SPC Moderate Risk. What culminated was widespread large hail, wind damage, and three tornadoes in Illinois.

A very brief tornado touched down IL just east of Illinois Route 4 and just north of Lower Marine Road where it collapsed the overhead doors of a metal building and caused minor roof damage to a double wide manufactured home. The tornado lifted shortly after.

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

28 minutes of warning. NWS LSX issued a tornado warning for this county at 18:13 UTC, 28 minutes before the tornado touched down, in force until 19:00 UTC.

The county was under a tornado watch, issued at 17:50 UTC and running to 01:36 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 Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 16:50 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.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The St Louis radar (KLSX), 77 km away, was scanning. The volume nearest the touchdown began at 18:41 UTC.

28 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.
