...NWS Damage Survey for 04/27/26 Tornado Event...

An additional tornado was surveyed in association with a line of 
storms that tracked across the area on the morning of April 27th.

Start Location:         6 S Madison / Monroe County / MO
Start Lat/Lon:          39.3831 / -92.2273

End Date:               04/27/2026
End Time:               07:44 AM CDT

End Lat/Lon:            39.3832 / -92.194

Survey Summary:
A brief EF-1 tornado touched down in southwestern Monroe County 
near Route M and Highway 151. The primary damage caused by this 
tornado was a farm just south of Highway 151. Numerous large tree 
limbs were broken on the property with one tree limb pointed to 
the west. One farm building was collapsed on the western side of 
the barn. The eastern facing part of the building which was 
attached to the cement slab was still standing, while the western 
facing part of the building had completely collapsed. Due to this,
we estimated slightly below the expected wind speed which also 
matched the surrounding tree damage. 

On the south side of the tornado, a rear inflow jet formed 
producing multiple straight-line wind damage reports. Damage was 
primarily across the southwest portion of Monroe County from 
Highway NN to just north of County Road 95. Damage was primarily 
to trees which were blown down facing easterly. However, damage 
did occur to two farms in which partial or near total collapses 
occurred to farm outbuildings. Winds likely reached up to 95 mph 
in the southern straight-line area. 

The National Weather Service would like to thank Steve Jones at 
Monroe County Emergency Management for their assistance with this 
survey.

...NWS Damage Survey for 04/17/2026 Tornado Event - Update #3...

.Update...

Further analysis of high resolution satellite imagery has allowed
for further refinement of the damage survey from the 04/17/2026
event. This included breaking the Central Missouri EF-0 tornado
into 2 separate EF-0 tornadoes, small adjustments to the 2 tornado 
tracks along the Missouri River in Eastern Missouri, and assigning
a rating of EF-0 to the previously unrated tornado in Eastern 
Missouri.
