KEY MESSAGES

- Light snow could bring minor travel impacts to portions of northwest Minnesota and the northern Red River Valley. The probability for 1 inch or greater of snow is about 60 percent.

- A stronger storm system arrives on Tuesday, bringing a wide range of winter impacts from accumulating snow and mixed precipitation to high winds. There is a 30-40 percent chance for moderate winter impacts.

- Much colder temperatures will arrive late week, with a 70 percent chance that wind chills drop to -30F or colder.

..Dangerously Cold Wind Chills Possible Late This Week

A reinforcing surge of cold air pours into the region heading into Thursday and Friday, with 850mb temps ranging from -30C to -20C. Overnight lows could fall well into the teens below zero, especially where the snow pack is heaviest. This, combined with north to northwest winds, could bring wind chill values down into the range of -40F to -30F each morning Friday through Sunday. For most areas, this is likely to be the coldest air of the season thus far.

AVIATION /06Z TAFS THROUGH 06Z TUESDAY/

Issued at 1110 PM CST Sun Dec 7 2025

Widespread MVFR to periodic IFR will prevail for the entirety of the TAF period. Brief rises to VFR are possible in the first six hours of the TAF period, however they will be shortlived. Snow this evening will continue to slide southward, primarily impacting GFK and FAR. Periodic visibility reductions to 1-2 SM can be expected to continue at FAR but should gradually improve through the night.

A brief break from snowfall will occur sometime between 09z and 14z, however the next round of snow will push from northwest to southeast through the morning. This band of snow will be a bit further north than tonight, so the primary impacted TAF sites will be GFK/TVF/BJI. Brief bursts of heavier snowfall may cause visibility reductions to below 1SM, with the potential for brief reductions to 1/4-1/2SM if the heaviest snowfall rates occur at the TAF sites. As we progress into late afternoon, wind shear will develop across the region, particularly on the southern periphery of the main snow line. This should diminish in intensity into the evening and overnight hours, although expect at least some wind shear to continue to linger after sunset. Snow will taper from west to east and the heaviest snow should be clear of the area by 06z, however flurries and light snow will likely continue at TVF and BJI. Winds will shift to northwesterly to westerly by the end of the TAF period.
