DISCUSSION

Issued at 236 PM CST Mon Jan 26 2026

Mainly sunny skies persist across the area this afternoon. Winds have turned southwesterly but remain breezy with gusts being observed up to 20-40 mph. The strongest winds reside along the Buffalo Ridge in southwest Minnesota. These stronger winds are resulting in patchy blowing snow in this area. While not widespread, minor reductions in visibility is possible. Winds will slowly weaken this evening but remain elevated out of the northwest tonight. Low temperatures will fall to the single digits to dipping just below 0F along the previously mentioned higher elevation areas in southwest Minnesota and east central South Dakota. Wind chills will not be as cold as this morning, but they will still get down to the single digits, teens, and even down to about 20F below zero.

Tuesday will be another quiet day. Temperatures will remain below average however as another cold surface high slides through the Northern Plains. High temperatures will remain in the single digits and teens with locations along highway-14 topping out at about 20F. Despite the high coming through, marginally breezy northwest winds will persist through the day. This will keep wind chills cold, with values remaining both above and below 0F throughout the daylight hours. Low temperatures will again fall to the single digits with higher elevation areas falling just barely blow 0F. Winds will weaken considerably, so wind chill values will only fall to positive and negative single digits.

Wednesday will be another quiet day with high temperatures warming to the teens and 20s. Thursday will be a bit cooler with highs in the single digits and teens. Peak high temperatures will just about touch 20F along the Missouri River Valley. The ensembles continue to show the chance for light snowfall on Thursday. Currently, the NBM, AIGFS Ensemble, and The LREF all show moderate to high probabilities (40-80%) for precipitation amounts to exceed a hundredth of an inch, highest across south central South Dakota. However, these probabilities rapidly diminish to a straight 0% chance for exceeding a tenth of an inch of liquid QPF. This makes sense given the lack of forcing associated with this light snow. Something to watch over the coming few days but certainly not an impactful amount of snow and wind. Surface ridging will be present across the Northern Plains Thursday night, making for another cold night with low temperatures falling to the negative single digits across the area.

Friday will be another quiet but cold day as high temperatures only warm to the single digits and teens. Temperatures will further warm to the 20s, 30s, and even low 40s over the weekend. Chances for light snow will also return to the area as well. The ensembles show moderate probabilities between 40-60% for a hundredth of an inch of liquid QPF. These probabilities again rapidly dwindle for probabilities for exceeding a tenth of an inch of more. Winds will also be on the lighter side as well.

Next Monday looks to see a continuation of warmer temperatures as upper level ridging from the northwestern CONUS pushes into the Plains.

VFR conditions will persist for the rest of the TAF period. Besides some mid to upper-level clouds, no aviation concerns are expected. Otherwise, occasionally breezy northwesterly winds will continue to decrease into the evening.
