DISCUSSION

Issued at 340 AM CST Sat Dec 13 2025

Winds have weakened overnight, though remain strong enough to hold wind chills as low as -20F to -30F early this morning. Most areas will warm about 5 to 10 degrees this afternoon, but winds also increase, limiting our recovery from the cold conditions. Temperatures crash again tonight, aided by clearing skies and persistent cold air advection from the northwest. Widespread wind chills as low as 35 below zero are expected again. The Cold Weather Advisory remains in effect through Sunday morning, after which winds shift out of the south and we are able to rebound a bit Sunday afternoon.

Light snow is ongoing this morning, stretching from Montana all the way down towards Iowa. This system will slide through the central US today, clipping the southwestern corner of Minnesota. Accumulations around a few tenths up to an inch at most expected for locations southwest of the MN river valley and along parts of the I-90 corridor. Blowing snow concerns are not as high today, though the breezy winds could still produce pockets of some drifting and blowing snow for any areas with a blowable snowpack.

Surface high pressure dominates the northern Plains through the rest of the weekend into early next week. One thing to watch for period of warmer temperatures will be the extent of cloud cover. Latest ensemble guidance favors denser, more persistent cloud cover, which would limit the ceiling for our highs and keep our lows well above average. Regardless, Tuesday and Wednesday should mark our first time above freezing in nearly 3 weeks!

Our next chance for precipitation comes in the form of a shortwave and associated Clipper Wednesday into Thursday. There could be another strong push of cold air behind this system, though it does not look to last that long as ridging quickly builds back in behind it. Depending on the exact track of the low, and the extent of how much we are able to warm up across the region, there could be precipitation type concerns with rain transitioning to snow or wintry mix. Winds could also get quite strong behind this system, with both the Euro and American models suggesting gusts on the order of 35 to 45 mph being possible Thursday.

AVIATION /12Z TAFS THROUGH 12Z SUNDAY/

Issued at 529 AM CST Sat Dec 13 2025

Snow has remained south of MKT and RWF this morning and have opted to remove from the TAF. Elsewhere, high stratus remains, but will scatter out this morning leaving partly clear skies with VFR conditions. Breezy NW winds will diminish late in the period, but remain steady between 10 and 20kts until then. There is a chance for high end MVFR cigs at RNH and EAU late tonight, but opted to keep TAF at low end VFR given low confidence. Forecast soundings indicate these lower ceilings could arrive as early as noon, but the chance is better later in the day with an increased RH layer. Nonetheless, dry conditions should lead to no impact.

KMSP...No additional concerns.

/OUTLOOK FOR KMSP/ SUN...VFR. Wind W early, bcmg S 5-10kts. MON...VFR. Wind S early, bcmg WNW 10-15kts. TUE...VFR. Wind SW 10-15G20kts.
