UPDATE

Issued at 951 PM CST Tue Jan 20 2026

Mostly cloudy skies continue with the lowest clouds across southeast North Dakota and west-central Minnesota. Beneath this cloud deck, falling snow has been observed but impacts to visibility have been nonimpactful (generally 7-10 miles visibility). This will continue through the overnight. We don't expect winds to start picking up until after 6 AM tomorrow, so blowing snow impacts shouldn't arise until after then.

UPDATE Issued at 656 PM CST Tue Jan 20 2026

Intermittent flurries will continue this evening but impacts will remain limited as visibility reductions and accumulations will be minimal. As such, no meaningful weather impacts should occur overnight.

..Dangerously Cold Wind Chills Thursday Through Sunday

Frigid, Arctic, air settles into the Northern Plains and Upper Midwest following Wednesday's cold front. Surface temperatures plummet Wednesday night into Thursday, with continued CAA through the day Thursday. Overnight lows fall into the teens below zero Wednesday night, then keep falling through the day on Thursday, settling into the 20s below to 30s below zero Thursday night and Friday morning. Wind chills are expected to fall into the range of 40 below zero to 60 below zero by early Friday morning.

AVIATION /06Z TAFS THROUGH 06Z THURSDAY/

Issued at 1127 PM CST Tue Jan 20 2026

Mostly cloudy skies will persist through the overnight with brief periods of MVFR ceilings expected. Snow will move from northwest to southeast beginning through 18z. With winds shifting and increasing from the northwest, visibility reductions to MVFR, IFR, and LIFR can be expected, with a low chance for VLIFR visibilities. VLIFR visibilities will mainly occur when snow is falling and combines with blowing snow. Widespread falling snow should come to an end late morning, however the development of afternoon snow showers is expected and may provide another chance in the afternoon for similar conditions. This will come to an end towards the evening hours, but MVFR ceilings will continue to persist.
