   below- normal temperatures heading into the weekend.

.NEAR TERM...
(Through Monday)
Issued at 1238 AM CST Mon Dec 8 2025

Low clouds will persist across the eastern two-thirds of Oklahoma
and may spread westward a bit through the early morning hours. Where
clear skies continue with light winds, across western Oklahoma and
into adjacent portions of western north Texas, radiational patchy to
areas of freezing fog may develop. Some localized areas of dense fog
remain possible, but confidence is low on exact location at this
time and an advisory will be issued based on hourly observations.
Temperatures are already below freezing as of midnight outside of
the low status deck across western Oklahoma. Temperatures under the
low clouds will be insolated and struggle to drop this morning. Any
fog that develops will dissipate by mid to late morning today, while
the low clouds may take a bit longer to clear out, especially across
central and eastern Oklahoma. Southerly surface winds will return in
the west as the surface high departs, allowing for warming
temperatures into the 50s where clouds can clear out, while highs
may be limited to the upper 40s across areas with lingering cloud
cover and slower heating.

.SHORT TERM...
(Monday night through Wednesday night)
Issued at 1238 AM CST Mon Dec 8 2025

Tuesday will start the warming trend through the week with
northwesterly flow aloft as a shortwave slides across the Midwest
and surface troughing develops to our west. Breezy and warm
southerly surface flow will give way to above-normal temperatures in
the 60s and even some areas across  western north Texas and
southwest Oklahoma approaching the lower 70s. South-southwesterly
winds will increase through the afternoon with gusts up to 20 to 25
mph possible.

A cold front will slide south across the area Tuesday night, but
with the surface low as far north as the Midwest and moving into the
Great Lakes Region, the bulk of colder air will likely remain north
of the forecast area. Wednesday may feature only about a 5 degree
drop in daytime highs from Tuesday. Thus, still expecting near to
above seasonable temperatures by midweek.

.LONG TERM...
(Thursday through Sunday)
Issued at 1238 AM CST Mon Dec 8 2025

Heading into the latter half of the week and into the weekend, the
pattern aloft continues to feature northwesterly flow aloft with a
strong jet digging into the Plains. There is decent confidence of
this cold front at the end of the week bringing cold air by the
weekend. However, the latest ensemble guidance indicates delay in
the timing of the coldest airmass. Grand ensemble temperature
spreads of the 25th vs 75th percentiles (upper quartile and lower
quartile) have narrowed with the most recent 12/8 00z model run and
generally have the coldest air not pushing into Oklahoma until
Saturday and nearly 5 degree spreads both Friday and Saturday (lower
to mid 50s and upper 30s to lower 40s, respectively). Cluster
analysis reveals nearly 80 percent of the models agree with this
delayed solution of the colder air, while 20 percent of the members
continues to dig cold air into the forecast area by Friday. The
extended forecast continues to remain dry with no precipitation
chances with these fronts.

.AVIATION...
(12Z TAFS)
Issued at 510 AM CST Mon Dec 8 2025

A low (LIFR/IFR/MVFR ceilings) stratus deck is expected to
persist through at least part of the day today at some sites.
There is some uncertainty as to the timing of when this deck will
begin to scatter out/dissipate. Some patchy fog is also possible
this morning. Winds will be light and variable this morning as sfc
high moves across the area. Winds will gradually shift towards the
S and SW later today and tonight.
