...NWS DAMAGE SURVEY FOR 12/28/2019 TORNADO EVENT...

.OVERVIEW...Broken lines of thunderstorms developed and moved through
eastern Oklahoma during the afternoon and early evening of December
28th. Although instability was weak, very strong low level wind shear
was more than enough to support the development of low level rotation
in a couple of the stronger convective lines. One such line produced
a weak tornado in Broken Arrow. The damage from this tornado was
assessed today by NWS Tulsa meteorologists, and the results of the
survey follow.
