..UPDATE...

AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.

VFR conditions expected through the period. Isolated thunderstorms
could affect FYV/XNA/ROG/FSM this afternoon, but areal coverage is
not expected to be enough to mention in the TAFs at this point.

PREV DISCUSSION... /Issued 217 AM CDT WED JUL 20 2016/

DISCUSSION...
Strong upper high, currently located over the central U.S., will
continue to dominate the overall weather pattern for the next
several days. Hot and humid conditions will persist with heat
indices again in the 105 to 108 degree range this afternoon across
much of eastern Oklahoma and west-central Arkansas. Given yesterdays
readings, a few additional counties were added to the heat advisory
(Cherokee/Delaware) in NE OK and Pushmataha and Choctaw counties
in far SE OK as high temperatures increase by a degree or two.

Still the possibility for a few isolated thunderstorms across far
southeast Oklahoma and northwest Arkansas this afternoon and to a
lesser extent Thursday afternoon. Overall precipitation coverage
will be limited at best.

Upper high will weaken slightly over the weekend which should
allow for a modest increase in precipitation chances, especially
by Monday/Tuesday as a weak frontal boundary approaches the
region from the north. Temperatures will be slightly lower and
closer to normal for this time of year, but overall still
hot and humid.
