Summary: UPDATED. The tornado began near the intersection of Will
Holt Road and Bobo Section Road where several large trees were
snapped and uprooted. Significant damage occurred just east of this
location, on Delynn Drive, where multiple trees were uprooted, some
of which fell onto nearby homes. Minor damage continued east along
Larkin Sullivan Road and Hills Chapel Road.

Damage previously noted along Bobo Section Road--which included
multiple snapped and uprooted trees, as well as damage to a few
sheds and farm buildings--is now thought to be associated with
strong rear-flank downdraft (RFD) winds. The rotation on Doppler
radar is consistently located north of Bobo Section Road, but the
RFD winds were particularly intense.

The most notable damage occurred once the tornado reached Highway
231, where the tornado hit a building supply yard and nearby houses.
More than a quarter of the shingles were removed from a single
family home and a nearby tree was twisted apart. At the building
supply store, metal roofing and siding covering the supplies were
completely removed and the underlying wooden support structure
broken. The metal roofing was strewn across the street and into a
field. Security video footage confirms the presence of a circulation
but the tornado appears to have been rain-wrapped. The tornado
caused further shingle damage and snapped more trees across the
highway near Walls Road and Leigh Ann Road, but the damage appears
to diminish quickly beyond this point.

EF Scale: The Enhanced Fujita Scale classifies tornadoes into the
following categories.

EF0...Weak......65 TO 85 mph
EF1...Weak......86 TO 110 mph
EF2...Strong....111 TO 135 mph
EF3...Strong....136 TO 165 mph
EF4...Violent...166 TO 200mph
