...NWS DAMAGE SURVEY FOR 05/18/17 TORNADO EVENT - UPDATE 2...

.UPDATE...UPDATED TO INCLUDE TORNADOES IN BENTONVILLE...NEAR
ASHLAND...NEAR SAVANNA...NEAR HANNA...NEAR STIDHAM...NEAR
CHECHOTAH...NEAR KEEFETON...AND NEAR BRAGGS.

.OVERVIEW...A line of severe thunderstorms moved through eastern
Oklahoma and northwestern Arkansas during the evening hours of May
18th and the early morning hours of the 19th. Strong instability and
very strong low level wind shear that was present across the area as
the storms moved through the region, supported the development of
persistent and strong low-level circulations along the leading edge
of the line of thunderstorms. These circulations resulted in the
development of at least 16 tornadoes that we have confirmed. NWS
Tulsa meteorologists have surveyed this damage over the past several
days, and their findings are detailed below.
