KEY MESSAGES

Updated at 1252 PM CST Tue Jan 27 2026

- Patchy to areas of freezing fog may impact portions of eastern Oklahoma and northwest Arkansas tonight into 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 tonight) Issued at 1252 PM CST Tue Jan 27 2026

Pleasant, albeit chilly, weather will prevail through the remainder of the daytime today and into tonight. A very weak and subtle frontal boundary will move into the northern portions of the CWA later this afternoon, but will have no impacts to the area other than a minor wind shift out of the north for areas north of I-40. Winds remain light and variable to near calm this evening and overnight tonight. The light winds and lingering snow/sleet on the ground will promote patchy to areas of freezing fog, locally dense, to develop this evening and into the overnight hours for much of eastern OK and northwest AR. The densest fog looks to stay along and south of I-40 before midnight, but is expected to spread northward some after midnight. Similar to last night, temperatures will rapidly fall after sunset this evening, with most locations dropping below freezing by or just after sunset. Freezing fog and residual snow/sleet/ice will continue to make travel and road conditions less than ideal, with black ice also remaining a threat. Continue to take it slow on the road and leave plenty of room between other vehicles around you.

LONG TERM

(Tomorrow through Tuesday) Issued at 1252 PM CST Tue Jan 27 2026

With very little boundary layer flow, freezing fog that develops tonight may linger through much of the morning Wednesday before lifting and eroding. Surface ridge axis will shift east of the forecast area late Wednesday morning and south/southwest winds will return by midday, which should help clear any remaining fog in the area. Mostly pleasant and milder, although still unseasonably cold, weather is in store Wednesday and Wednesday night, with daytime highs reaching the upper 30s and lower 40s and overnight lows dipping into the low-mid 20s for most locations.

Thursday starts off chilly with additional freezing fog in places in the morning. A mid-level shortwave trough will eject off the Rockies overnight Wednesday night into Thursday morning and will help push a surface cold front through the area Thursday afternoon. Models still show a hint of light precipitation associated with the frontal boundary and upper-level system. Will maintain low PoPs (20% of light rain/snow) for areas of far northeast OK and far northwest AR Thursday afternoon/evening. Models show a more vigorous shortwave trough/low digging south from the Great Lakes/Ohio Valley Region during the daytime Friday and eventually positioning itself over the southeast CONUS by Saturday afternoon. The wave will bring a secondary push of cold air into the region on Friday, and perhaps bring additional low chances of light snow/flurries for portions of the area.

Bitterly cold temperatures will return beginning Thursday night following the cold front during the daytime. Overnight lows into Friday morning will fall into the teens, with wind chill values reaching the single digits. The secondary push of cold air during the day on Friday will cause temperatures to fall further, with overnight lows in the single digits, and wind chill values near or below zero, for most locations Friday night into Saturday morning. Cold weather headlines will likely be needed for Friday night. Temperatures will remain unseasonably cold during the daytime Saturday and into Saturday night. Temperatures will rebound and will steadily warm-up Sunday, Monday, and Tuesday.

AVIATION

(18Z TAFS) Issued at 1233 PM CST Tue Jan 27 2026

VFR conditions will prevail through the remainder of this afternoon for all sites. Mid and high cloud move through the region from west to east this afternoon, before exiting this evening. Overnight, freezing fog development will be possible areawide, with KMLC and KFSM having the highest chance of significantly reduced vsbys (LIFR) and slick spots, especially between 08-15z. Probabilities for dense freezing fog are less across NW AR sites, trends will be monitored for future forecasts. Conditions may be slow to improve Wednesday morning for sites experiencing fog, especially across SE OK and W-Central AR, and fog may lift into a low cloud base before eroding.
