Survey Summary:
This tornado developed just north of County Road 1701 southeast
of Hominy, where trees were uprooted and snapped. The tornado
moved northeast and crossed Highway 20, snapping numerous trees
and snapping seven metal power poles. The tornado continued to
snap and uproot numerous trees between Highway 20 and Barnsdall.
Significant tree damage was found in several locations. The
tornado then moved into Barnsdall, causing severe damage to the
wax plant on the southeast side of town, and then severely
damaged or destroyed numerous homes on the east side of town.
Several homes and a well-built, metal-framed building suggested
estimated wind speed in the 150 to 165 mph range, and one home
suggested estimated wind speed of 165 to 175 mph, which is in the
EF-4 category. Numerous trees were snubbed in the area of some of
the higher end damage, which was supportive of these wind speed
estimates.

Significant tree damage continued northeast of Barnsdall, a few homes
were damaged, and outbuildings were destroyed between Barnsdall and
Bartlesville. The tornado moved across the southern portion of
Bartlesville, and then across the eastern side of town. Lots of trees
were snapped or uprooted, and numerous homes and businesses were
damaged in town. A squall line merged with the tornadic supercell,
and ultimately ended the tornado process on the northeast side of
Bartlesville.
