.SHORT TERM...
(Today)
Issued at 1224 AM CDT Sun Aug 10 2025

Low-level thermal ridging extending from the southern High Plains
northeast into the central/southern Plains will continue to bring
dangerous heat to close out the weekend. While the intensity of the
LLTR is expected to back off a bit, the hot temps and humidity are
expected to yield near advisory level heat indices across a good
portion of E OK and the lower Ark River Valley and thus one more day
of heat headlines. Uncertainties regarding outflow/cloud
cover/storms increase across the north toward the KS border however,
so it`s possible that this portion of the advisory may not verify.

CAMs show a strong signal for more widespread convection tonight
across NE/KS/MO/IA in association with the interaction between a
strengthening LLJ and a frontal boundary. An outflow boundary is
likely to drop south from these storms to near the KS border by
around daybreak. CAMs have some showers and storms developing across
far NE OK into far NW AR during the morning, probably in association
with the outflow. Some scattered afternoon storms are also possible
across NE OK and NW AR near the residual boundary, while some
isolated mainly diurnal activity is possible over W AR and far E OK.
Strong, gusty winds and locally heavy rainfall will be the main
threats.

.LONG TERM...
(Tonight through Saturday)
Issued at 1224 AM CDT Sun Aug 10 2025

A shortwave trough, currently dropping south over the Intermountain
West, is expected to bring what looks to be the best rain/storm
chances for this forecast beginning Sunday night and possibly
lasting into Tuesday. While details differ amongst the CAMs, the
general idea of an MCS moving across KS/OK Sunday night into Monday
morning is there. What is also suggested is that storms will lose
steam with eastward extent into the forecast area toward Monday
morning. Looks like there will be additional storm development on
Monday afternoon near the outflow from the previous night`s storms.
The most likely scenarios in the ensemble cluster data also suggest
an uptick in rain/storm chances Monday night over our northern and
western areas, lingering into Tuesday. Gusty winds and locally heavy
rainfall will remain the main threats, and WPC has highlighted NE OK
and far NW AR in a Marginal flash flood risk for Monday. In addition
to the higher rain chances, the low level thermal ridge collapses
and retracts back to the west, allowing for relatively cooler temps
and an end to the heat headlines.

For the latter half of the week, upper troughing will be prevalent
along the West Coast, while ridging develops over the Southeast/Gulf
Coast region. High temps will climb again, but should be closer to
average for this time of year and not quite as hot as they have been
recently. There will be generally low diurnally-driven and mainly
terrain-induced storm chances across W AR and far E OK as well.

.AVIATION...
(06Z TAFS)
Issued at 1224 AM CDT Sun Aug 10 2025

Mostly VFR conditions expected through the period outside of some
thunderstorm impacts possible this morning and afternoon and again
late tonight. A cluster of storms moving through Kansas could
potentially impact KBVO later this morning with lowered
VSBY at times. More scattered thunderstorm development is possible
during the afternoon along any remnant outflow boundaries across
NE OK and NW AR sites. Another cluster of storms is also forecast
for late tonight with potential impacts into NE OK sites by the
end of the TAF period. Southerly winds will also increase this
morning with gusts around 20 knots possible through the day with
higher gusts possible within any thunderstorms.
