More extensive freezing fog Tuesday night/Wednesday morning. - Travel conditions will be slow to improve as cold temperatures persist through early week, though some temperature moderation is expected.

SHORT TERM

(Through Tuesday) Issued at 1045 PM CST Mon Jan 26 2026

Cold conditions continue this evening and into the overnight, with just how cold governed by wind trends. For example, at the time of the writing of this sentence, the mesonet site at Webbers Falls had calm winds and a temperature of 4 degrees, while surrounding sites are reporting temperatures in the 20s with 5 to 10 mph of wind speed. With clear skies and the existing snow/sleet pack, expect spatial and temporal disparities such as this to continue for much of the night. Even in locations that see comparatively warmer temperatures, the wind that is reponsible for that will likely lead to wind chills that at times are well below zero. As a result, the existing Extreme Cold Warning will be left alone for now. Patchy freezing fog will remain a possibility, especially in the Lower Arkansas River Valley and far southeast Oklahoma, where winds are more likely to go calm. Any freezing fog could exacerbate already slick roadways resulting from refreezing of the sleet/snow that melted during the day today.

Speaking of melting, temperatures should rise above freezing in most of the region today, leading to additional erosion of the sleet and snow pack this afternoon. Increasing mid/high cloud cover and a weak boundary will limit the overall warmup across parts of northeast Oklahoma and northwest Arkansas but parts of southeast Oklahoma and west central Arkansas may approach 40 degrees for a high.

LONG TERM

(Tuesday Night through Monday) Issued at 1045 PM CST Mon Jan 26 2026

A more extensive round of freezing fog late Tuesday night and into Wednesday remains supported by a good chunk of the data, particularly across areas to the south of I-40 nearer the surface ridge axis and slightly higher low level moisture. A Freezing Fog Advisory may be required on later shifts if trends remain similar to what they are currently.

A cold front will move through the region Thursday, although the stronger reinforcing front remains on track for Friday. A strong and fairly fast moving disturbance associated with the Thursday front will bring a low chance of rain/snow to areas east of Highway 75 and along/south of Highway 412 Thursday evening. Little to no snow accumulation is expected from this. Behind the reinforcing front on Friday, another round of dangerous, potentially life-threatening cold is expected Friday night. Additional cold weather advisory/warnings may be required.

Warmer conditions develop Sunday, with noticeably warmer temperatures to start the next work week.
