- Strong to severe storms are possible late this evening into
   overnight to with the main risk north of I-40. The main severe
   hazards would be large hail & damaging wind gusts with a low
   tornado risk.
- Storm chances continue Tuesday into Tuesday night across
   southern Oklahoma and into western north Texas. Storms may
   become severe with large hail and damaging winds with that risk
   area highest in southeast Oklahoma.
- A cold front on Tuesday will bring cooler near-normal
   temperatures by mid-week.

(Rest of today and tonight)
Issued at 154 PM CDT Mon Sep 22 2025
There remains a Slight Risk for severe thunderstorms late tonight
across our northern CWA.  Otherwise warm to hot and muggy today
under weak upper ridging.  Hottest especially across southern
Oklahoma and western north Texas where surface moisture is highest
producing heat index values just about 100 degree.
A positively tilted trough will remain in place across the Central
Rockies of Colorado & Utah although may not be digging into the
Southern Plains till the end of the short-term period?  However a
series of shortwaves embedded downstream from the main trough will
be moving across our area as an MCS late this evening & overnight.
Meanwhile a second trough/system across the Upper Midwest/Great
Lakes Region will be pushing an initial surface front across the
Central Plains and into our area although latest guidance suggesting
it may not arrive into our northern CWA until perhaps a few hours
before Sunrise Wednesday morning.  Should the surface front not
arrive earlier than expected then early morning convection would be
elevated with the MCS coming through. However strong southerly low-
level jet flow between the 925-850 mb layer may be sufficient in
transporting gulf moisture into the mid-levels fueling the shortwave
forcing for storm activity. The more aggressive NAM projecting
strong elevated instability with more moderate MUCAPE values with
the ECMWF model as most likely solution would be in-between. Both
solutions agree with strong deep-layer shear with the southerly low-
level winds veering westerly aloft. With this environment still
could see severe storms tonight across our CWA generally north of I-
40 which could produce large hail across far northern Oklahoma to
damaging wind gusts down to I-40. The tornado risk remains low but
can`t rule it out based on the strong shear & moisture values.
Northcentral Oklahoma could also see the heaviest rainfall which
could pose an additional flooding hazard.  As a result have a 3-
county Flood Watch in effect in northcentral Oklahoma.

.SHORT TERM...
(Tuesday through Wednesday night)
Issued at 154 PM CDT Mon Sep 22 2025
The aforementioned surface front is expected to pushing through our
area Tuesday afternoon keeping low rain/storm POPS in our area.  By
late afternoon heating could see surface-based storms initiate along
and ahead of the surface boundary where the environment will be
moderately unstable and strongly sheared.  Expecting the surface
boundary to be near to east and south of the I-44 corridor where the
lower-end severe risk will with the higher-end risk in southeast
Oklahoma.  Severe hazards remain large hail & damaging wind gusts
with a low but not completely zero risk for a tornado, with that
risk higher in eastern Oklahoma.
By late Tuesday into Wednesday all of our area should be post-
frontal as the aforementioned positively tilted trough starts
digging into the Central & Southern High Plains.  This will maintain
low rain/storm POPs but in a weaker unstable environment should
minimize the severe risks.  Being post-frontal on Wednesday with a
reinforcing cold front coming through and northwest winds, will see
temperatures go below average and milder with highs in the mid 70s
to lower 80s and a cooler night with widespread lows in the 50s.

.LONG TERM...
(Thursday through Sunday)
Issued at 1209 AM CDT Mon Sep 22 2025
Precipitation chances will decrease significantly Thursday through
the weekend with an Omega Block pattern slowly bringing a ridge over
the Plains. Southeasterly surface flow will keep temperatures near-
normal (80s) Thursday and Friday as the surface high spins to our
east. However, temperatures will creep a bit warmer (near or
slightly above average) by the weekend as the surface ridge
strengthens and the upper ridge passes over the forecast area.

(00Z TAFS)
Issued at 632 PM CDT Mon Sep 22 2025
Mid and high clouds will continue to increase ahead of an
approaching shortwave trough. Late this evening and overnight,
scattered to numerous showers and thunderstorms are expected
to develop, especially across Kansas and parts of northern
Oklahoma.
A cold front will move into northwestern Oklahoma around 12-14Z
and will push south and east during the day. Low clouds should
developing behind the front with mainly MVFR ceilings (perhaps IFR
near WWR). Additional showers and thunderstorms should develop
along the front Tuesday afternoon. This may impact OKC/OUN with a
better chance at DUA after 00Z Wednesday.
Through at least 5-6Z Tuesday, VFR conditions are expected with
a southerly wind. There is also a chance of LLWS developing at
mainly the LAW/SPS terminals after 5-6Z and lasting through
12-13Z Tuesday.
