Strong to severe thunderstorms developed across portions of eastern Oklahoma during the afternoon and evening of the 19th, as a frontal boundary moved into the area. Very unstable air combined with weak wind shear resulted in intense but relatively short-lived thunderstorms, the strongest of which produced damaging outflow wind.

- Dangerous heat persists areawide today, and for southeast OK on Wednesday.
- A cold front moves into/through the region tonight and
Wednesday bringing increasing shower and thunderstorm chances
as well as somewhat cooler air.
- Another cold front is forecast late weekend into next week with
increased rain chances and well below normal temperatures
expected.

.SHORT TERM...
(Through tonight )
Issued at 1248 PM CDT Tue Aug 19 2025
Upper level ridging is now well to the west of the area, but a very
hot lower level thermal profile remains in place. Heat indices will
peak this afternoon at 105-110 F for most of the area. Decent
instability with some weak forcing from an approaching shortwave
trough will kick off isolated showers and storms this afternoon
and evening, particularly across the higher terrain and near the
KS border. Storm activity will spread south into the rest of the
area this evening or overnight but coverage will remain scattered
(10-40% chance). A few storms could become marginally severe with
damaging wind gusts and locally heavy rainfall. Low temperatures
tonight will remain mild, mostly in the 70s, but will be somewhat
cooler than this morning as cooler air filters in from the north.
&&
.LONG TERM...
(Tomorrow through Tuesday)
Issued at 1248 PM CDT Tue Aug 19 2025
The cold front will continue pushing south Wednesday. Northern areas
will be mostly dry, with only a 10-20% chance of a shower or
thunderstorm Wednesday. High temperatures will drop to the upper 80s
to low 90s as cold air advection increases slightly. There will be a
better chance of precipitation further south (closer to the front).
High temperatures and heat indices will cool slightly from today for
areas near I-40 and south, but remain high enough to justify one
final Heat Advisory. Though this should be the last one for now.
Conditions will then dry out for the remainder of the week with
temperatures running near or a bit below normal. Rain chances will
generally remain 15% or less until the weekend.
By next Sunday an anomalously deep trough will dive into the eastern
USA. It will weaken and further displace the high pressure area to
the west. Significantly cooler air will move in, with conditions
perhaps feeling more like late September or early October than late
August. Highs will fall into the 70s to low 80s, possibly lower.
With high PWAT due to robust moisture transport along the low level
jet, sufficient instability, and good upper level forcing, rain
chances will likely rise considerably. There is good ensemble
support for multiple rounds of widespread (and possibly heavy
rainfall). With that said there is timing uncertainty as well as
uncertainty with respect to the areas where rain will focus. For
that reason, Pops are still mostly below 50%. Either way, this will
be a substantial change from the weather seen lately.

.AVIATION...
(18Z TAFS)
Issued at 1225 PM CDT Tue Aug 19 2025
Scattered thunderstorms will re-develop through this afternoon,
potentially with greater coverage across NW AR and eventually SE
OK through early evening. Strong downdraft winds may occur with
strongest cells along with substantial short-duration reduction in
visibility. Overall activity should diminish overnight with VFR
conditions prevailing outside of direct storm impacts.

AREA...Eastern Oklahoma and Western Arkansas.
ONSET...Ongoing.
DISCUSSION...
Isolated to scattered thunderstorms are ongoing late this
afternoon in parts of eastern Oklahoma and western Arkansas. The
thunderstorms will continue to pose a locally heavy rain and gusty
wind threat, with a limited potential for damaging wind gusts with
the strongest thunderstorms. The coverage and intensity of
thunderstorms are both expected to wane with the loss of daytime
heating, although low thunderstorm chances will persist overnight.
In areas that have not seen cooling rains this afternoon, hot and
humid conditions persist, with heat index values from 100 to 110
degrees continuing. Conditions will improve toward sunset.
SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Local Spotter Activation May Be Needed.
.DAYS TWO THROUGH SEVEN...Wednesday through Monday.
WEDNESDAY...Thunderstorm and Dangerous Heat Potential.
THURSDAY THROUGH SATURDAY...No Hazards.
SUNDAY AND MONDAY...Thunderstorm Potential.
EXTENDED DISCUSSION...
Thunderstorm chances will focus southward on Wednesday primarily
across southeast Oklahoma into west central Arkansas. Hot and
humid conditions will remain in place, especially for areas south
of Interstate 40, before slightly cooler and drier air arrives
Thursday through Saturday. The weather pattern begins to change by
early next week, with daily shower and thunderstorm chances and below
normal temperatures.
