KEY MESSAGES

- Snow showers accompanied by gusty winds will cause blowing snow tonight through Friday. This will sharply reduce visibility impacting travel conditions, and a winter weather advisory is in effect.

- Wind chill values fall into the range of 30 below zero to 40 below zero Saturday morning and Monday morning

- Potential for another impactful system Sunday with a 60% chance for greater than 1" of snow in northwest MN and wind gusts over 45 mph.

..Sunday Clipper

Beyond this ongoing system is another well modeled clipper that will move through Sunday with an EFI signal stronger than todays over the area for wind signaling the potential for winds of upwards of 50 mph. While the QPF signal is less than todays system, NBM probs for greater than 1" are still as high as 60% for the northern RRV and northwest Minnesota. Taking into account air temps in the single digits during falling snow would say warning impacts are certainly possible but only during falling snow as there is a low chance to achieve the magical 2" threshold for prolonged blowing after the falling component ceases. For areas of eastern ND that don't see any falling snow an EFI signal of 0.9 (as is currently being shown) or higher typically correlates well with high wind warning criteria. Combined with the shift of tails indicating the higher end outliers still present in ensemble guidance. Certainly dont want skip over todays system but there may be another notable/impactful one on its heels come Sunday that is worth mentioning. Timing of the main impacts looks to be Sunday morning into the late evening coinciding with the strong cold air advection with the attendant cold front as the trough drops south.

..Cold wind chills Saturday morning

With the arctic air firmly in place Friday night into Saturday, temperatures will drop below zero and continue down into the teens below. With northwest winds continuing at least 25 to 35 mph with higher gusts, wind chills will drop down into the -30 to -40 range. Will likely need some sort of cold headline, but given short term impacts will hold off for now.

AVIATION /06Z TAFS THROUGH 06Z SATURDAY/

Issued at 1131 PM CST Thu Jan 15 2026

Most sites are VFR currently with SCT or SKC above 3000ft but snow will soon be moving in with lowering cigs from the west with increasing winds. MVFR most common thorugh the period but short IFR cigs and vis possible as snow bands move over terminals through the period. Expect prevailing conditions to improve towards the tail end of the period as winds decrease. Winds NW 25-30mph and gusts of 40-45mph common at all sites expect BJI. Overall gonna be a lot of Tempos or AMDS most likely.
