KEY MESSAGES

Updated at 1153 AM CST Sat Dec 6 2025

- A Dense Fog Advisory continues until 1 PM; additional dense fog expected late Saturday and Sunday morning.

- Cooler day on Sunday behind a front before dry and seasonable weather into next week.

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.

AVIATION

(18Z TAFS) Issued at 1153 AM CST Sat Dec 6 2025

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.
