During the evening hours on June 5th, storms move into portions of Buffalo and Trempealeau counties producing large hail and strong winds. Eventually, these storms formed into a line and pushed southeast into portions of La Crosse, Monroe and Juneau Counties bring additional large hail, damaging wind gusts and an EF-0 tornado in eastern Monroe County prior to storms exiting to the southeast.

This very short-lived EF-0 tornado damaged some stands of trees as it moved through portions of eastern Monroe County.

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. One was issued for the county at another hour that day.

The county was under a severe thunderstorm watch, issued at 20:26 UTC and running to 03:12 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 Slight Risk. The outlook in force was issued at 01:00 UTC.

2 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.
