...New SHORT TERM, LONG TERM...

.SHORT TERM...
(The rest of this afternoon )
Issued at 111 PM CDT Tue Aug 9 2022
Scattered showers with a few embedded thunderstorms continue this
afternoon in association with several weak MCVs that were generated
earlier in the day during the stronger convection. Although spotty,
some beneficial rainfall has occurred across southeast Oklahoma,
currently in extreme (D3) drought. Still the potential for lingering
scattered storms this afternoon, including northeast Oklahoma
where atmosphere has destabilized with the thinner cloud cover.

&&

.LONG TERM...
(Tonight through Tuesday)
Issued at 111 PM CDT Tue Aug 9 2022

Modest low level jet will develop tonight with scattered storms
possible into Wednesday morning. Main precip area on Wednesday
will begin to focus further south as drier air begins to filter
into the region from the northeast.

Upper high currently over the Four Corners Region will begin to
shift east closer to the area with warm/humid conditions likely
through the weekend. High temperatures will again approach triple
digits early next week with excessive heat becoming more of a
concern. Overall rain chances through the extended periods will
likely remain low, however isolated storms possible Friday afternoon
across far southeast Oklahoma and across northwest Arkansas by
Tuesday of next week.

&&

.AVIATION...
(18Z TAFS)
Issued at 1217 PM CDT Tue Aug 9 2022

RA/isolated TSRA continue across far ERN OK and NW AR early this
afternoon, so will keep varying mentions of RA/TSRA for the first
few hours of the period across the SE OK/AR sites. VFR elements largely
to prevail for the remainder of the period though additional scattered
development overnight may impact the SE OK and AR sites after 06z
with MVFR vsbys. Will include a few hours of PROB30 groups at
those sites.
