Record number

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

Several trees uprooted or snapped. Railcars were overturned. Grain bins were significantly damaged. Outbuilding were destroyed. Several power poles were snapped and broken. Additional modifications to the path are possible after satellite data review.

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

11 damage points were recorded along this path by NWS SGF, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 105 mph.

• Two trees on property facing southwest
• Four empty grain bin railcars tipped over. The rest remained upright. Rail cars were upright at time of survey.
• This grain bin took the most damage. It was bolted in and those were ripped out on the northwest side. Drbris was laying against other grain bins.
• Side wall was collapsed along with loss of roof.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

Severe storms triggered by a potent weather system swept through far southeastern Kansas, bringing destructive winds and large hail. These storms were part of a 15-hour severe weather outbreak that impacted central and eastern Kansas finally moving into Missouri.

A National Weather Service storm survey determined that an EF1 Tornado with estimated wind speeds of 105 mph touched down near the northeast portion of Hallowell before tracking 4.37 miles to the east. The tornado uprooted or snapped several trees, overturned several empty railcars, caused significant damaged to several grain bins, destroyed multiple outbuildings and snapped or broke numerous power poles and downed power lines. The tornado track ended approximately 1.25 miles east of Sherwin.

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

59 minutes of warning. NWS SGF issued a tornado warning for this county at 01:44 UTC, 59 minutes before the tornado touched down, in force until 02:45 UTC.

The county was under a tornado watch, issued at 20:25 UTC and running to 03:56 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, 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 01:05 UTC.

9 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.
