Record number

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

The tornado touched down about 4 miles southwest of Galesburg where it damaged a few trees before heading northeast toward Galesburg. The tornado did primarily tree damage as it crossed Galesburg and went into East Galesburg. The tornado dissipated just east of East Galesburg.

Written by NWS ILX in the NWS Damage Assessment Toolkit. A survey is revised as better evidence arrives.

23 damage points were recorded along this path by NWS ILX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 88 mph.

• Tree snapped and fell into house
• Branches snapped off and is being cleaned up
• Cluster of tree branches snapped
• Branches chopped up already

6 minutes of warning. NWS ILX issued a tornado warning for this county at 22:19 UTC, 6 minutes before the tornado touched down, in force until 23:00 UTC.

The county was under a tornado watch, issued at 18:43 UTC and running to 01:28 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 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 19:56 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 Quad Cities radar (KDVN), 79 km away, was scanning. The volume nearest the touchdown began at 22:24 UTC.

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.
