KEY MESSAGES

- Light snow gradually ends this evening from northwest to southeast.

- Below average temperatures continue into next week as Arctic air pushes southward into the Northern Plains and Upper Midwest. There is a low chance for minor winter impacts towards the end of the week.

..Synopsis

North to northwest H5 flow will bring a surge of Arctic air into the region tonight, with reinforcing cold air by mid week. Temperatures are expected to be well below average through the forecast period, with several chances to fall below zero. The best chances will be where we have the deepest snow pack, generally in southeast North Dakota and west central Minnesota. A shortwave brings precipitation chances back into the area late Tuesday night into Wednesday, with some uncertainty regarding the availability of moisture. Most ensemble guidance is hinting at generally low QPF and snow potential. Temps at 850mb have good support down into the -25C to - 20C range heading into Thursday, following the cold front. A second system approaches toward the end of the week, with slightly better moisture potential; however, ensemble spread at this time is too high to support any single solution.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1128 AM CST Sat Nov 29 2025

Light snow continues to bring IFR visibility and ceilings to many of the regional TAF sites heading into the early afternoon hours. Visibility is generally around 1-2 SM during snowfall, with P6SM outside of actively falling snow. Looking forward, KDVL should start to improve prior to 22Z as the system continues moving east. All sites will eventually see improvements later this evening; however, MVFR ceilings could persist a bit longer at KBJI and KTVF.
