KEY MESSAGES

- Falling and blowing snow will bring winter impacts in Minnesota for locations along and south of Highway 2 through midnight.

- Below normal temperatures arrive behind this system with several low chances of snow.

UPDATE

Issued at 900 PM CST Tue Nov 25 2025

The primary deformation zone/axis of 700 MB frontogensis on the NW quadrant of the mid level low continues to track east, and with it the main period of accumulating snow is coming to an end west to east. THere are still areas of lighter snow farther to the northwest (minimal additional accumulations) and since the strongest winds have continue to trend down vis impacts have also improved greatly. I went ahead and allowed the warnings in the southern RRV expire and trimmed off some of the counties in the winter weather advisory in MN. I held onto the warning and advisory in our east where the main band of snow is still lingering through midnight tonight.

Even though the weather impacts are improving, roads remain slick and road impacts may continue to linger into the night. ND/MN DOT road condition websites travel.dot.nd.gov and 511mn.org should be checked for road conditions/status.

UPDATE Issued at 602 PM CST Tue Nov 25 2025

The main areas/bands of moderate to locally heavy snow have shifted southeast of Fargo and the improving trend that had already started in northeast ND has arrived in Barnes/Cass counties. This matched the timing of the expiration for those counties and the winter weather advisory was allowed to expire in our ND counties. Farther south where these snow rates combined with winds gusting to 45 mph are lingering in SE ND. We are still seeing webcams/surface obs/plowcams showing near blizzard conditions, and this will continue over the next few hours until the main area of snow transitions east. For now no other changes were made to hazard products in far southeast ND and northwest/west central MN.

..Cold into the Weekend

While the airmass drug in behind this system will be much colder then we have seen over the past week, the true "crash" of arctic air will not arrive until the weekend, when high temperatures drop into the teens above zero. Overnight lows during this same time will be in the single digits just above or more likely below zero. As we ride the baroclinic zone Thursday into early Saturday, an open wave will push along to our south/southwest. Isentropic ascent should lead to a broad area of light snow with the eastern/northern edges of it near our western FA border. Where exactly the baroclinic zone sets up will determine how much of the area sees snow from this system, as a majority of ensemble members want to keep it a bit more to our west, which would keep most of the snow to the west as well.

AVIATION /00Z TAFS THROUGH 00Z THURSDAY/

Issued at 536 PM CST Tue Nov 25 2025

Snow and blowing snow impacts are lingering over southeast ND and parts of northwest MN. Lowest visibilities associated with moderate to heavy snowfall banding has shifted east-southeast of TAF sites (KFAR and KBJI) however lingering vis reductions in the IFR to MVFR categories should be expected due to lighter snow combined with gusty northerly winds. Farther north visibilities have improved, however larger areas of MVFR ceilings linger. While there may be brief breaks or "holes" within this stratus layer they should not result in prolonged/prevailing VFR conditions before filling back in. By Wednesday morning this stratus begin to break up, but due to the flow on the backside of the departing upper low streamers or "bands" of MVFR stratus are likely to redevelop. Strongest winds early in the TAF period should gradually decrease as they shift to the northwest and gradient starts to relax, but they should remain above 12kt through the TAF period.
