KEY MESSAGES

- Light snow and gusty winds Tuesday evening into early Wednesday morning. This may degrade travel conditions, particularly within the southern Red River Valley.

- Intervals of below average temperatures through the rest of the week, along with snow chances after Thursday.

UPDATE

Issued at 702 PM CST Mon Dec 1 2025

Stratus/flurries are lingering in MN which mostly clear skies are in place across more of ND (though there have been a few stubborn pockets rebuilding in northeast ND). In the regions of clearing temperatures are dropping quickly as would be expected especially over regions with deeper snowpack. Near term adjustments were made to reflect current trends.

..Variable temperatures and snow chances late week

While ensemble guidance is in rather good agreement on northwest flow aloft late this week, they do disagree in evolution of several shortwave troughs riding a baroclinic zone paralleling flow aloft. Should these troughs move closer to our area, chance for snow as well as snow amounts would increase. This may result in several days of periodic snow chances, including accumulations that may be impactful. The evolution and track of these shortwave troughs will also influence winds across the region, bringing their own potential for impacts.

Regardless, confidence is too low to comment on potential for impacts beyond Thursday from snow and wind, as predictability in synoptic evolution/track as well as mesoscale features is too low.

AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/

Issued at 541 PM CST Mon Dec 1 2025

MVFR stratus lingers in northwest MN with the clearing line stalling as additional clouds have filled back in over parts of the Red River Valley where VFR is still prevailing, but pockets of MVFR are moving west to east. Due to weakening BL flow and low levels stabilizing trends support this stratus in MN holding and eventually IFR developing later this evening/overnight. Prevailing VFR is favored in eastern ND through Tuesday morning, but may not arrive until mixing and BL flow increases from the south then southwest in MN.

A mid level wave moves through the region Tuesday and a cold front arrives late afternoon and evening resulting in a period of light snow across the region. The best chances for accumulating snow and visibility reductions would be in northeast ND and northwest MN late in the TAF period based on current guidance. This front will bring shifting winds from the south to the west and eventually northwest Tuesday afternoon and evening.
