...NWS DAMAGE SURVEY FOR 05/27/17 TORNADO EVENT...

.OVERVIEW...A supercell produced two tornadoes in Okfuskee County,
Oklahoma, during the evening. These tornadoes were observed by
several storm chasers and local residents. Each was on the ground
for several minutes. NWS Tulsa meteorologists conducted a damage
survey of the affected area of Okfuskee County on the 28th, but
were unable to access the areas where these tornadoes likely
occurred due to flooded roads, washed out roads, or gated roads.
Some tree damage was noted in both areas, but it was determined
that this was the result of strong wind likely associated with the
rear-flank downdraft of the supercell and/or inflow into the
storm, rather than from the tornadoes. We are still investigating
these areas with the help of local emergency management, and will
update our findings, as appropriate. Photos and video of the
tornadoes indicate some debris was lofted, but at this time, the
tornadoes will be rated EF-0 or EF-unknown due to our inability to
access any of the damage.

Several hours later, a bowing line segment developed a strong
cyclonic circulation just north of its apex as it moved into
eastern Sequoyah County, Oklahoma. A tornado developed near Short,
Oklahoma, from this circulation. This tornado passed across
Uniontown and Cedarville, Arkansas. This damage was also assessed
by our survey team on the 28th, and detailed findings are noted
below.

bowing line segment near Short, Oklahoma. It uprooted trees and
snapped large tree limbs as it moved east-northeast toward the
state line. At the state line, the tornado destroyed the roof of a
mobile home, damaged outbuildings, and uprooted trees. Numerous trees
were snapped or uprooted as it moved across Higway 59 and Arkansas

southeast of Natural Dam.
