.NEAR TERM...
(Through Saturday)
Issued at 1246 AM CST Sat Dec 6 2025

Areas of dense fog are expected to develop this morning with the
highest confidence east of the I-44 corridor. Patchy fog, some
dense, will also be possible west and north of I-44 with lower
confidence. A Dense Fog Advisory remains in effect through 10 AM
Saturday across portions of central Oklahoma with visibility of a
quarter mile or less probable. Generally where the dense fog is
expected, temperatures will hover at or above freezing. However,
there is a chance for some freezing fog to develop through the early
morning hours near the I-44 corridor with some slick roadways
possible.

A majority of the fog will begin to dissipate through mid-morning,
however there is a potential for pockets of dense fog to linger
through the early afternoon hours across southeast Oklahoma. Mostly
clear skies and breezy southerly winds across western Oklahoma and
western north Texas will bring WAA and near-normal temperatures in
the upper 50s to lower 60s this afternoon. Temperatures will be
slightly cooler across central and southeast Oklahoma (mid-50s) as
the fog slowly clears out today. A few models suggest the low clouds
linger through the entire day which could limit heating through the
afternoon hours and result in cooler high temperatures, potentially
not even warming out of the 40s. Thus, high temperatures today have
been lowered from the NBM to account for this increasing potential.

.SHORT TERM...
(Saturday night through Monday night)
Issued at 1246 AM CST Sat Dec 6 2025

Models are trending towards a return of fog across southeast
Oklahoma after midnight, but the dry cold front will sweep southward
and erode any fog development by around sunrise which is when the
front will be completely through the state of Oklahoma. There will
be a slight delay in the colder air with fairly mild temperatures
for this time of year by Sunday morning. However some breezy north
post-frontal winds could make for a brisk morning. As the front
continues to push southward into central Texas Sunday, breezy north
winds will continue with gusts up to 20 to 25 mph possible.
Temperatures will be nearly 5-10 degrees colder than Saturday making
for a chilly end to the weekend. The surface high will continue dig
southward into Oklahoma Sunday night with widespread below freezing
temperatures. Drier air behind the front should also mitigate any
fog development.

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

Cooler temperatures will linger into Monday before a warming trend
the remainder of the week with above seasonable temperatures. 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.

.AVIATION...
(12Z TAFS)
Issued at 503 AM CST Sat Dec 6 2025

IFR/LIFR conditions at some TAF sites due to fog/low clouds. The
fog is expected to dissipate later this morning although fog could
develop again this evening/overnight at least for a brief period
of time before a cold front and drier air moves into the area. The
cold front and a sfc low moving across the area will cause
shifting winds today with winds eventually shifting to the NW
behind the cold front.
