.SHORT TERM...
(Through Sunday)
Issued at 1048 PM CST Sat Nov 22 2025

Widespread stratus remains stubborn over northwest AR and a large
portion of northeast OK, and hasn`t shown much sign of erosion. High-
res model guidance continues to struggle handling this scenario, and
with surface high anchored over the forecast area tonight and fairly
deep inversion up to about 850mb noted on 00z sounding from KSGF, a
more pessimistic forecast of cloud cover will be made through
tonight. This also lends uncertainty to fog potential, though still
would expect further reductions to vis across parts of northwest AR,
where several stations reporting 3-5sm. Area most susceptible to
more widespread dense fog will be outside of the stratus deck, but
has not happened yet.

Any fog or low clouds will likely be slow to break up Sunday until a
little stronger low level flow becomes established. Those areas that
are able to clear should warm into the low-mid 60s, but more
persistent clouds would hold them down considerably. It`s that
time of year.

.LONG TERM...
(Sunday Night through Saturday)
Issued at 1048 PM CST Sat Nov 22 2025

Upper low in the Southwest is forecast to continue lifting northeast
into the Central Plains by Sunday night into Monday. In response,
deep moisture will surge northward across much of the Southern
Plains with development of widespread showers and some embedded
thunderstorms as forcing begins to spread over increasingly moist
airmass. Given forecast precipitable water values above 95th
percentile by early Monday morning, any thunderstorms will be
efficient rainfall producers. Stronger wind fields also arriving
could aid in storm organization, however the greatest instability
will likely focus south of the Red River, thus the severe weather
threat will be limited to mainly southeast OK and perhaps west
central AR. An additional surge of precip during the day Monday
corresponds with arrival of strong upper jet streak, again with
instability mainly elevated and confined to areas south of I-40.
Rainfall amounts still look on the order of 1 to 2 inches from
southeast OK into west central AR, with some higher totals, with
lesser amounts to the north and west.

Dry weather returns as the upper low departs Monday with
temperatures remaining mild until a stronger cold front pushes
through Tuesday. This should bring temperatures back down below
normal with a period of gusty northwest winds Tuesday night into
Wednesday. This cool down looks short-lived as the surface low
quickly moves east by Friday, and moisture begins to return next
weekend ahead of another approaching system.

.AVIATION...
(12Z TAFS)
Issued at 550 AM CST Sun Nov 23 2025

LIFR/IFR conditions early Sunday morning are forecast to slowly
become IFR/MVFR into Sunday afternoon and remain scattered to
overcast into Sunday evening. Shower and thunderstorm chances
increase from west to east Sunday evening/night over the CWA with
the greater thunder potential along and south of Interstate 40.
Will continue with Tempo groups for timing of greater precip
potential for all TAF sites. Within the precip and continuing
through the end of the TAF period will be the potential for MVFR
conditions. Winds through the period start out light/variable and
become southerly this afternoon/evening. The exception being KFSM
were a more easterly wind is forecast through the period.
