KEY MESSAGES

- Below average temperatures continue into next week as Arctic air pushes southward into the Northern Plains and Upper Midwest. Periodic light snow and flurry chances this week.

UPDATE

Issued at 1134 PM CST Sun Nov 30 2025

Clouds moving into our southwestern counties have continued to be a bit slower than expected, so a few spots in the southern Red River Valley have dropped into the double digits below zero. May have to watch for patchy fog formation along the edge of the stratus deck but so far probabilities for visibility less than 1 mile through tomorrow morning is below 20 percent, so will keep an eye on it for now.

UPDATE Issued at 936 PM CST Sun Nov 30 2025

Decreased lows a few degrees in portions of southeastern ND and far west central MN with snow cover. Readings are already in the -5 to -10 range, and while clouds are on their way they are coming in a bit slower than expected and should see another few degree drop into the upper single digits to 10 below zero. Adjusted clouds for current satellite trends.

UPDATE Issued at 557 PM CST Sun Nov 30 2025

Adjusted cloud cover for clearing in our western and southern counties, but should be short lived as more clouds already see on satellite coming in from the southwest. The clouds should slow the free falling temperatures in the southern counties which are already starting to drop below zero with fresh snow. Think that will steady out in the upper single digits as clouds come in, but will keep an eye on how readings trend.

..Synopsis

Colder than average temperatures continue through the forecast period as north to northwest H5 flow prevails. Scattered low to mid level cloud cover today is expected to persist into the overnight and into Monday, with flurries possible wherever clouds exist. Low temperatures tonight will ultimately depend upon where the clearest skies persist, with lows generally expected to fall either side of zero degrees. Another shortwave approaches the area Tuesday into Wednesday, with light snow possible, along with a surge of reinforcing Arctic air. The 850 mb temps could be as low as 20 below zero for portions of the area, with surface temps in the teens below zero, especially where snow cover is heaviest.

Heading into the end of next week, another shortwave will be followed by additional chances for snow on Friday and into the weekend. Overall, the medium range pattern supports additional cold air and occasional snow chances over the next couple of weeks.

AVIATION /06Z TAFS THROUGH 06Z TUESDAY/

Issued at 1134 PM CST Sun Nov 30 2025

Southwesterly winds continue to bring a threat for stratus to southwestern portions of our forecast area, although it still has yet to get close to KFAR. KDVL is being impacted by IFR stratus and flurries coming off of the lake. Should see the Red River Valley airports dropping down to MVFR, possibly IFR, towards tomorrow morning. The ND side should see some improvement to VFR by the tail end of the period. The MN airports will see some brief clearing in the next few hours before MVFR to IFR ceilings move back in later tomorrow. Can't completely rule out some patchy BR or even FG forming, but not confident enough to put into the TAFs as at this point stratus seems more likely. Winds will remain mostly southwesterly at around 10 kts.
