KEY MESSAGES

Updated at 1236 AM CST Sun Dec 7 2025

- A Dense Fog Advisory continues until 6 AM this morning. Visibility reductions may cause hazardous travel conditions.

- Cooler day on Sunday behind a front before dry and seasonable weather into the middle of this week.

- Another cold front Thursday may bring a return to chilly below- normal temperatures heading into next week.

NEAR TERM

(Through Sunday) Issued at 1236 AM CST Sun Dec 7 2025

Another day, another morning of fog. Areas of fog, some dense, have developed yesterday evening across much of central and southern Oklahoma and into western north Texas. A surface low is moving east across north Texas and has brought a north wind to southern Oklahoma and into western north Texas. However, the true front with the drier and colder air is moving into northwest Oklahoma and will push south through the entire area by later this morning. This front will clear out any low clouds and fog in its path. Some patchy fog, potentially dense, and low clouds may linger a few hours past sunrise across southeast Oklahoma before the dry air finally fills in. Post-frontal north winds may pick up this morning and into the afternoon hours with gusts up to 20 to 25 mph possible. As the surface high sinks southward today, a cooler post-frontal airmass will keep high temperatures from rising generally above the 40s to mid 50s.

SHORT TERM

(Sunday night through Tuesday night) Issued at 1236 AM CST Sun Dec 7 2025

Light winds and mostly clear skies will give way to radiational cooling Sunday night and temperatures plummeting into the 20s. There is a small potential for some low clouds to develop Sunday night across eastern Oklahoma and creep westward into central Oklahoma before clearing through Monday morning. In the wake of the previous shortwave and cold front, northwesterly flow will persist aloft but surface flow will return to the south. Thus, warm air advection will return to the forecast area with highs warming back to normal in the 50s.

LONG TERM

(Wednesday through Saturday) Issued at 1236 AM CST Sun Dec 7 2025

The extended forecast continues to be dry with persistent northwesterly flow aloft and embedded shortwaves with rounds of cool Canadian air digging into the CONUS. Tuesday through Thursday will feature above seasonable temperatures. A shortwave with a strong jet to our north will bring a front through Tuesday night into Wednesday morning across the forecast area with much of the colder air keeping to the north. Another shortwave will bring a front through Thursday, but this time a strong jet streak of 150 knots up to 250mb will give way to deep cold air pushed southward into much of the eastern half of the CONUS by the weekend. Temperatures Friday could be nearly 20 degrees colder than Thursday and persist through the weekend. Ensemble guidance continues to show a large spread in temperatures for Friday from the mid 30s to lower 50s. Cluster analysis reveals about 50 percent of the models lie near the 50th percentile of the NBM (current forecast). Meanwhile, the other 50 percent is split with one cluster having a strong warm signal with temperatures leaning closer to the 90th percentile of NBM, while the other cluster is slightly cooler and leaning towards the 25th percentile of the NBM. With still a wide variation of outcomes with the ensembles, a lot is likely to change given Friday is still five days out. Trends will continue to be monitored for a unified solution.

AVIATION

(06Z TAFS) Issued at 1027 PM CST Sat Dec 6 2025

A cold front has pushed into northwest Oklahoma and will continue to move across our terminals between 07-10Z producing a north wind shift around 10 kts behind the front. Expecting visibilities to further reduce for a few hours just ahead the approaching front maintaining LIFR conditions. Ceilings should rise with improving visibilities gradually behind the cold front/wind shift to at least a MVFR category. Will expect all terminals to return to a VFR category between 16-20Z. North surface winds will increase after 17Z gusting up to 20 kts and going light & variable after 01Z.
