Record number

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

A combination of NWS ground surveys and Sentinel-2 satellite analysis concluded that an EF1 tornado began within a forested area in far western Douglas County and tracked 8.9 miles, passing by Arden, and ending southeast of Tigris. Along the track, the tornado produced an intermittent path of extensive tree damage and caused roof damage to a couple outbuildings and pushed a manufactured home several feet. The tornado peaked with estimated winds of 100 mph and was 400 yards at its widest point.

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

32 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 100 mph.

• Trees laying west through south
• Trees uprooted in a cyclonic manner
• Large tree branch snapped off.
• Tree damage noted via Sentinel-2 data.

Severe thunderstorms swept through the Missouri Ozarks during the evening and overnight hours of June 7th and 8th. Several tornadoes occurred along with significant flash flooding. Between 2 and 6 inches of rainfall fell over a short period of time across portions of southwest Missouri.

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

4 minutes of warning. NWS SGF issued a tornado warning for this county at 01:43 UTC, 4 minutes before the tornado touched down, in force until 02:30 UTC.

The county was under a tornado watch, issued at 01:18 UTC and running to 02:55 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. The outlook in force was issued at 01:00 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 Springfield radar (KSGF), 59 km away, was scanning. The volume nearest the touchdown began at 01:46 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.
