UPDATE

Issued at 1000 PM CST Thu Nov 27 2025

Unsurprisingly the quite night is yielding some nuisance snow across eastern North Dakota and northwest Minnesota. Fairly large flakes were observed here at the office as visibility at GFK dropped to 2 miles for a short period but not much more than maybe a tenth fell. This activity continues south through the night with most areas receiving a trace. Impact: flurry warning.

UPDATE Issued at 523 PM CST Thu Nov 27 2025

Currently fog or anything less than 2SM visibility looks most favored across the Missouri coteau and west missing our area. Overall would say the chance for fog is less than 10% but given the favorable forecast conditions (fresh snowpack, clear-ish skies, and high pressure) will keep it in the forecast for now in southeast North Dakota.

..Colder Weather

While temperatures have cooled the past few days behind the departing low pressure system on Tuesday, the largest drop in temperatures will come behind the Saturday system this weekend. The coldest air of the season so far will settle in to end the weekend and start the work week. Low temperatures Monday morning are forecast to be below zero across the entire FA, but depending on the exact placement of the high pressure Sunday night, temperatures may manage to get a bit colder then what is shown right now. We should moderate a little bit next Tuesday/Wednesday as ensembles hint at a wave coming through, before northwest flow dumps another chunk of arctic air into the Northern Plains at the tail end of the forecast period late next week.
