.SHORT TERM...
(Through tonight)
Issued at 255 PM CDT Fri Jun 13 2025

A mid-upper level low was clearly defined on water vapor imagery
this afternoon, positioned in southern Missouri, and drifting
east- northeast. As the low departs, isolated to scattered showers
and thunderstorms will persist this evening, primarily across far
eastern Oklahoma and northwest Arkansas. Precip may continue into
the overnight hours, but with lessening coverage. Then, by late
overnight into tomorrow morning, increasing WAA will increase
shower and storm potential again along a moist axis in N-Central/
NE Oklahoma. Heavy rainfall will continue to be a concern with
precip through tonight, and localized flash flooding may develop
quickly given seasonably high PWATs. Additionally, while shear
will remain weak, moderate instability and sufficiently steep
lapse rates may allow storms to become strong to severe late
tonight/ tomorrow morning across northeast Oklahoma. Marginally
severe hail and wind gusts will be the primary hazard... along
with the previously mentioned flash flooding potential.

.LONG TERM...
(Tomorrow through Friday)
Issued at 255 PM CDT Fri Jun 13 2025

Following the exit of today`s upper low, ridging expands across
the desert southwest and places our area under north-northwest
flow aloft. Showers and thunderstorms may be ongoing tomorrow
morning across northeast Oklahoma and perhaps extending into
northwest Arkansas. As the nocturnal jet weakens, storm intensity
and coverage should tend to decrease through the morning hours.
Considerable spread remains regarding convective evolution
tomorrow afternoon, but at least some potential exists for
redevelopment with diurnal heating... especially along any remnant
outflow boundaries. If this occurs, moderate to strong
instability and sufficient lapse rates would likely support some
severe potential, despite generally weak shear.

Saturday evening and overnight, a wave embedded in the flow aloft
will drift into the region, potentially igniting additional
storms across southern Kansas/ northeast Oklahoma. Various models
have hinted at fairly robust convection and potential development
into an MCS if storms materialize. While shear will be modest,
sufficient instability and low level lapse rates should support
severe weather potential with this activity. Damaging wind gusts,
very heavy rainfall leading to areas of flash flooding, and large
hail would be the primary hazards with any activity during the
afternoon hours and/or overnight. As with the previous forecast,
have gone above NBM PoPs to account for storm potential
tomorrow... but PoPs may still be too low during this period and
adjustments may be required in following forecasts.

Low chances for showers and thunderstorms continue into Sunday
and Monday. The environment will likely continue to support at
least limited severe weather and heavy rainfall/ flash flooding
threats through the remainder of the weekend... with additional
MCS activity not out of question. Preceding convective/mesoscale
evolution will likely play a large role in the determination of
severe timing and locations most at risk this weekend. With this
in mind, please continue to monitor the forecast over the coming
days as finer details become better resolved.

It appears the FA may have a break from the rainfall late Monday
into Tuesday as shortwave ridging briefly expands into the S
Plains. However, by late Tuesday into Wednesday, an amplified
trough is forecast to move into the plains, dragging a weak front
down with it. The front is projected to slow and eventually stall
somewhere in or near our area, with additional shower and
thunderstorm chances through early Thursday. By late next week,
upper ridging appears to expand into the region and intensify in a
much more summer-like pattern. This will likely bring much drier
conditions and put an end to our very rainy stretch. Temperatures
will gradually increase this weekend, climbing into the lower to
mid 90s by next week, which is slightly above average. Warming
temperatures and high dewpoints are likely to lead to the first
stretch of heat indices approaching or exceeding 100 across the
area next week.

.AVIATION...
(00Z TAFS)
Issued at 629 PM CDT Fri Jun 13 2025

Scattered convection is redeveloping along a surface boundary near a
SWO-MKO-FSM line this evening, with other scattered activity
redevoping in far nwrn AR. Expect this activity for a few hours into
the forecast period then activity should wane. MVFR visibilities in
fog is possible at most sites after 06z, especially nwrn AR sites,
including some IFR. Still a signal in the latest CAMs suggesting
another round of TSRA late tonight/Saturday morning ern OK sites.
Some morning MVFR CIGS/VSBYS becoming VFR by late morning. Depending
on where the morning convection develops, more convection is possible
Saturday afternoon/evening along the outflow boundary, which at this
time seems most likely to affect the southernmost sites MLC/FSM.
