.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
Showers just now entering portions of northeast Oklahoma,
accompanied by isolated lightning strikes. However there has been
an overall weakening trend noted over the last couple of hours.
Rain will continue to spread across the area after midnight, but
conditions will likely remain VFR for a few more hours. Although
there may be isolated showers across western Arkansas overnight,
the heavier rain will likely hold off until late morning or early
afternoon. Have added thunder for a few of the sites from Tulsa
south for mid morning or afternoon.

..UPDATE...

DISCUSSION...
Band of showers, maybe with a few embedded thunderstorms, are
expected to move into portions of northeast Oklahoma late tonight
as strong upper level storm system approaches from the west. Main
precipitation, including any isolated thunderstorm activity, will
likely remain west of Highway 75, although elevated instability
will remain marginal. Also, latest 00Z model guidance/CAMs have a
little bit slower progression with precip, so lowered pops somewhat
further east. No other changes anticipated at this time.
