KEY MESSAGES

- A strong, Arctic front arrives tonight into Friday, bringing a period of 20-25 mph winds with gusts ranging from 30-40 mph. This will lead to areas of travel impacts from isolated to scattered whiteout conditions, especially in open country.

- An Arctic air mass, along with breezy northwest winds, will bring dangerously cold wind chills into the region Friday through Sunday. Wind chills Saturday and Sunday mornings could fall as low as -40F.

..Dangerously Cold Wind Chills Friday through Sunday

Frigid, Arctic air moves into the Northern Plains and Upper Midwest following tonight's cold front. Friday's high temperatures (single digits either side of zero) will most likely occur around midnight tonight, with temps falling throughout much of the day. Lows Friday night into Saturday morning are expected to fall into the teens below zero to near 20 below zero, along with northwest winds ranging from 7 to 12 mph. This brings wind chill values into the range of 30 below zero to 40 below zero as cold air advection begins to taper off heading into Saturday. The coldest temps arrive Saturday evening into the early overnight hours, with many areas seeing air temps in the 20s below zero. Although winds will not be as strong, wind chills will still approach -40F due to the slightly colder air temperatures. Winds shift to the south after sunrise on Sunday, allowing temperatures to gradually climb above zero during the afternoon.

AVIATION /00Z TAFS THROUGH 00Z FRIDAY/

Issued at 516 PM CST Thu Dec 11 2025

Ceilings will begin to lower and winds will pick up from the northwest over the next 6 hours as a front pushes east through the region. Snow will accompany this, but given light rates, the primary concern to visibility will be blowing snow. Periodic visibility reductions as low as 1/4-1/2SM are possible mainly after 06z, lasting through the day. Ceilings will become low end MVFR to IFR through at least 12z as the main snow line pushes east. While VFR ceilings can be expected after 12z at DVL/GFK/FAR, the aforementioned blowing snow will continue to reduce visibility at times through the end of the TAF period.
