.NEAR TERM...
(Today and tonight)
Issued at 1152 AM CST Sat Dec 6 2025

Widespread dense fog remains entrenched across the southeastern one-
half of Oklahoma and portions of western-north Texas. While gradual
dissipation will continue into the early afternoon, the overall
breadth of fog coverage, along with continued light winds and
minimal temperature/moisture advection, will likely allow at least
patchy dense fog to linger towards 1-2 PM. Irregardless of how long
dense fog lasts, with low clouds likely persisting towards
sunset, locally coolest/cold afternoon temperatures (in the 40s)
are expected across south-central and central Oklahoma.

For our friends west of a Seymour-Elk City-Enid arc, there is hardly
a cloud in the sky at midday. Temperatures are expected to warm into
the upper-50s to low-60s with a breezy southwest wind (owing to
the pressure response from a nearby weak surface cyclone).

Fog looks to return this evening, possibly just after sunset where
temperatures remain coolest during the daytime. Dense fog
(visibility <1/4-mile) is also likely across portions of
southwestern, central and southern Oklahoma and western-north Texas
ahead of an approaching surface front into Sunday morning. With a
drier airmass filtering in behind the front, the temporal character
of dense fog concern is somewhat uncertain, especially from
southwestern into central Oklahoma. While a Dense Fog Advisory is
likely again late this evening/Sunday morning, will hold off on
fog headlines at this update. Fortunately, overnight lows are
expected to remain a few degrees above freezing such that freezing
fog will not be a concern with tonight`s fog episode.

.SHORT TERM...
(Sunday through Monday night)
Issued at 1152 AM CST Sat Dec 6 2025

Sunday will be a cooler day behind the front, as fringes of a
1029-mb surface high impinge across the area. A gusty northerly
wind in the morning will create brisk conditions (wind chills in
the 20s) if you have outdoor plans on Sunday morning. Daytime
temperatures won`t feel markedly warmer, with areas north of the
I-40 corridor likely to remain in the 40s. Should low clouds hang
around longer than currently anticipated, some locales near the
Oklahoma-Kansas border may struggle to warm out of the 30s.

Conditions will begin to moderate by Monday, as the previous surface
high begins to depart to the south and east. Afternoon temperatures
in the 50s to near 60-degrees (across the west) are currently
advertised.

.LONG TERM...
(Tuesday through Friday)
Issued at 1246 AM CST Sat Dec 6 2025

A brief weak backdoor cold front will move through Wednesday, but
most of the colder airmass will keep northeast of the forecast
area as the upper jet associated with the system slides across the
Central Plains and into the Ohio Valley, taking much of the
colder air with it. In the wake of that shortwave will be a
stronger longwave trough embedded in the northwesterly flow aloft
that will dig much colder air into the CONUS. Ensemble spread of
temperatures increases for Friday highs with temperatures ranging
from the lower 30s to upper 40s. Cluster analysis is about a 50/50
split towards the 25th and 75th percentile temperatures. These
temperature spreads will continue to be monitored through the
week.

LIFR conditions continue for KOKC, KOUN, KLAW and KSPS at this
hour. Dense fog is expected to lift this afternoon and then return
this evening into the overnight hours. As a front moves through
tomorrow morning, dry air moves in and improving conditions are
expected.
