...New AVIATION...

.SHORT TERM...
(The rest of today )
Issued at 924 AM CDT Sun Jun 9 2024

A cold front is currently pushing into northeast OK. Behind the
front, much cooler and drier air is filtering into the area. These
areas will mostly remain in the 70s for the remainder of the day,
with CAMs continuing to show persistent low cloud cover.

West and south of the front temperatures are much warmer and more
humid. These areas will see high temperatures in the 80s to 90s
with even higher heat indices. Showers and thunderstorms are
beginning to develop along the front. In general, this should
continue as it slowly moves southeast into the afternoon. Storms
are expected to remain sub severe, though there is a marginal
(5%) possibility of an isolated severe storm. Overall the lack of
widespread coverage should keep the risk of flash flooding low as
well.

.LONG TERM...
(Tonight through Saturday)
Issued at 404 AM CDT Sun Jun 9 2024

The frontal boundary is forecast to be across far Southeast
Oklahoma and exiting Northwest Arkansas this evening and then
finally exiting Southeast Oklahoma overnight tonight. Shower and
thunderstorm chances will continue with the front into the
overnight hours. Instability weakens and becomes mainly elevated
through the evening hours and as such severe potentials should
also decrease this evening. The 850-mb frontal boundary is
forecast to sag south of the Red River Monday morning with precip
chances exiting by Monday afternoon.

Cooler conditions...high temps in the 80s...continue Monday over
the CWA in the wake of the departing frontal boundary and should
continue into Tuesday as another weak area of low pressure slides
southeast through the Southern Plains. Additional shower and
thunderstorm chances return Tuesday with this shortwave and look
to exit Wednesday. The greater precip potential looks to be
Tuesday night into Wednesday across Southeast Oklahoma as the wave
moves through the region. Instability is forecast to be marginal
Tuesday/Wednesday and severe weather is not currently anticipated
for the CWA.

Once the shortwave exits mid week...mid level heights are forecast
to rise with a ridge of high pressure late week. In response...a
warming trend and more humid conditions are forecast Thursday into
the weekend. Extended model solutions indicate a shortwave moving
through the Plains late weekend...which may bring a return of
precip chances to the CWA...depending on the track of the low. As
of this forecast package...will hold off on mentionable PoPs for
now but is some thing to keep an eye on for the weekend.

(18Z TAFS)
Issued at 1148 AM CDT Sun Jun 9 2024

A cold front will pass through the area today. For terminals
behind the front in northeast OK, additional precipitation is
unlikely (10% chance). However, CIGs of 2-5 kft will prevail
through the afternoon before lifting and breaking up in the
evening. Winds will be out of the northeast at 5-15 kts.

For northwest AR, scattered showers and storms will persist
through the afternoon before ending. CIGs of 2-5 kft will break up
later this evening. The same can be expected for terminals in
southeast OK, but the timing will be shifted. Storms will develop
later this afternoon and into the evening, with CIGs lifting and
breaking up overnight. Winds will shift to northeast in these
areas as well over the next couple of hours.
