KEY MESSAGES

- Our next chance for precipitation will be Wednesday night into Thursday, then once more this weekend.

UPDATE

Issued at 527 AM CDT Tue Sep 22 2026

Southeast wind 5 to 10 mph over the entire forecast area at 09z. This wind and also some advection of low level moisture with higher dew pts are aiding to keep many spots from dropping into the frost range. But we do have pockets where winds are near calm and radiational cooling has been maximized and temps have dropped into the 32-36 range. Coolest readings south of Lake of the Woods and pockets of lower temps via NDAWN stations from western Cass county ND into western Grand Forks and central Walsh county ND. Also cold spots normally around Lake Itasca down to near 32F as well. Will maintain frost adv thru 12-13z.

..Frost Possible Tonight into Tuesday Morning

Low temperatures tonight are expected to fall into the middle 30s to upper 30s, primarily in northwest Minnesota (60 percent chance), with a lower chance (20 percent) in the northern Red River Valley and far northeast North Dakota. Radiational cooling is expected to be efficient as winds go nearly calm tonight across the area. Dew points will generally be in the middle to upper 30s as well, thus limiting the floor of lower temps. Patchy ground fog could form in cooler spots around sunrise.

AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/

Issued at 1142 PM CDT Mon Sep 21 2026

VFR will continue throughout the TAF period at all terminals. There will be a deck of clouds that forms overnight around KFAR with bases around 5,000 ft AGL, but being VFR, no aviation impacts are expected. Winds will be calm and variable overnight, then become southeasterly for Tuesday at up to 12 knots. There will be several hours during the afternoon of gusts up to about 20 knots at KGFK, KDVL and KFAR. Winds will decrease quickly Tuesday evening around sunset.
