KEY MESSAGES

Updated at 1025 PM CST Tue Jan 27 2026

- Patchy to areas of dense freezing fog likely across southeast Oklahoma and west central Arkansas late tonight through much of Wednesday morning. - Reinforcing cold front with low chances for precipitation late in the week.

- Very cold wind chills expected Friday night into Saturday morning, with minimum wind chill values below zero.

SHORT TERM

(Through Wednesday) Issued at 1025 PM CST Tue Jan 27 2026

High clouds continue to move across the region tonight, but satellite trends indicate they will eventually scatter from the west after midnight and mostly east of the area by early Wednesday morning. Some moistening of the boundary layer has occurred generally along and south of I-40, where current temp/dew point spreads are now just a few degrees, with a bit drier conditions persisting to the north. Given light winds and the eventual loss of higher clouds, appears that at least patchy dense fog is likely, and with temperatures falling into the teens and single digits, the potential for enough freezing fog to induce additional travel issues is high enough to warrant an advisory, which will run from 09-16z.

With continued light boundary layer flow most of Wednesday, any fog or low clouds could take some time to dissipate, but most areas should eventually see enough sun to bring temperatures back above freezing Wednesday afternoon, similar to what was observed today.

LONG TERM

(Wednesday Night through Tuesday) Issued at 1025 PM CST Tue Jan 27 2026

Milder conditions Wednesday night with more consistent south winds ahead of an approaching shortwave moving through the Rockies. This system may result in a few light rain or snow showers across mainly far northeast Ok and northwest AR Thursday, but POPs remain below mentionable for the most part and do not expect any impacts from any snow. A cold front will move through in the wake of this system later Thursday with cooling effects beginning Thursday night. A much more substantial push of cold Arctic air will then arrive by Friday, with temperatures dropping back into the single digits or even a bit below zero by Saturday morning, with anticipated wind chills likely necessitating cold weather headlines at that time. A few flurries also likely with this cold surge, but again nothing impactful in the way of precipitation.

After a very cold day Saturday, temperatues should begin to modify, though this will continue to be tempered early next week with expected lingering snowpack. By next Tuesday moist air from will increase from the south and result in a chance of rain as an upper system approaches from the west.

AVIATION

(06Z TAFS) Issued at 1014 PM CST Tue Jan 27 2026

Potential for freezing fog at mainly MLC and FSM continues to be the main aviation problem, with half mile visibilities and IFR ceilings remaining possible around daybreak into mid morning Wednesday. The chance remains nonzero at TUL/RVS and FYV/XNA/ROG but is much lower than the MLC/FSM. Will continue with TEMPOs for MVFR visibilities around daybreak at those 5 sites, with BVO remaining the only terminal without a visibility restriction mentioned. Clear skies should be expected once the fog lifts by midday, continuing into the overnight.
