DISCUSSION

Issued at 320 AM CST Sun Jan 25 2026

Elongated arctic high centered along the US/Canadian border covering much of the lower 48 east of the Rockies leading to widespread surface temperatures in the single digits above and below zero across the northern US. Short wave that brought snow to the region over the last day has worked into the southeastern US with additional waves in Texas and New Mexico leading to more active weather across the southern portions of the US. Any additional accumulations are expected to be fairly light this morning, generally an inch of snow or less, with the greatest accumulations across central Missouri. Frigid temperatures are expected today with 925 HPA temperatures hovering around -16 C. With clearing skies and arctic high pressure building south across the Western Plains tonight, atmosphere is setting up good radiative conditions over the fresh snow cover across the region. Models suggests there is the potential for a few low clouds that may spoil the nearly idealized radiative conditions. Regardless, it will still be extremely cold tonight, and even with a breath of wind, wind chills are expected to be in the -15 to -20 F range Monday morning. Models are giving about a 10% chance of temperatures falling to near record levels. Because of the extreme temperatures/wind chills, have issued a cold air advisory running from midnight through 9 AM Monday morning. Westerly winds gradually turn southwesterly on Monday leading to warming conditions across the region.

Temperatures are not expected to fall appreciably Monday evening after sunset as stronger winds develop keeping the atmosphere weakly mixed. This gives the region a warmer start on Tuesday morning, but a cold front is expected to drop south across the region mid-day. NBM has hedged towards the warmer side of guidance, but if the timing of the cold front is early enough in the day, it may be difficult warm as much as the current forecast suggests.

Flow turns westerly again on Wednesday leading to a brief warm up ahead of another push of arctic air building into the area from the north. The near surface northerly flow looks to remain through the end of the week, keeping temperatures well below normal and sub- freezing regionwide.
