144 FXUS63 KFGF 101856 AFDFGF Area Forecast Discussion National Weather Service Grand Forks ND 1256 PM CST Wed Dec 10 2025 .KEY MESSAGES... - Additional periods of light snow through Thursday night. Probability of total snow of more than 3 inches is 30 percent in far southeast North Dakota through this period. - Brief but intense cold snap Friday into Saturday, 80 percent chance for wind chills to drop to -30F or colder. && .UPDATE... Issued at 1244 PM CST Wed Dec 10 2025 Snow continues across the region except for within the Red River Valley where drying is occurring perhaps a bit quicker than expected, as indicative of rapidly clearing skies from north to south. Otherwise, sentiments in the previous update remain valid. UPDATE Issued at 1023 AM CST Wed Dec 10 2025 Stratiform and HCR-type snow showers are prevalent on radar and satellite. This is anticipated to continue into the early afternoon before moisture and forcing diminishes to a point where snow diminishes. While snow showers are of the HCR variety, they are rather weak, with limited visibility reductions down to around 1 mile at times, but not likely less than 1 mile. While snow will be light, it is very fluffy. Thus, up to around 1 inch of additional snow is expected today. Winds will remain out of the north 10-20 mph through the afternoon. This will promote drifting snow in open country, particularly in areas that received new accumulations since yesterday afternoon. UPDATE Issued at 554 AM CST Wed Dec 10 2025 Band of light snow is moving east and back edge is at the Red River. Lingering snow showers or flurries though west of this is likely in stratocu. && .DISCUSSION... Issued at 340 AM CST Wed Dec 10 2025 ...Synopsis... Main 500 short wave and sfc moving quickly southeast into southwest Wisconsin and northeast Iowa at 09z. There is a 500 mb short wave trough axis extending north into the Red River valley causing an additional area of light snow. This light snow area moves gradually east today and weakens. In this light snow area thru noon half inch of snow is likely in the Red River valley 10z to 16z period with potential for 1 inch. Winds are gusty in the far southern valley with gusts 30 mph Wahpeton but farther north gusts are gone with winds in the 15-20 mph range. With blowing snow not an issue, did coord with BIS and DLH and we dropped the winter weather advisory around 09z. There will be additional short waves moving east and southeast from southern and central Alberta thru Thursday night. Impacts are mainly in regards to freezing rain potential not in our area but from parts of Montana thru SW ND into SD. Light snow periodic tonight thru Thursday night, with the Thursday night light snow along an arctic cold front that will move through. This front will bring a 2 day cold snap with wind chills likely to drop to -30F and lower. 20 percent chance of wind chills -40F and lower for a time Saturday morning. 500 mb flow goes more zonal quickly next week with temperatures moderating. To what degree they moderate or rise to is uncertain due to snowcover. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/... Issued at 1244 PM CST Wed Dec 10 2025 Generally low confidence TAF, mainly due to lingering stratiform snow mixed with snow showers creating variable conditions ranging between VFR and IFR. Ceilings are bouncing around between VFR and MVFR, whereas visibility at times are dipping into IFR, particularly within snow showers. This is anticipated to be the case until around 21Z when moisture and forcing diminishes enough to cease snow shower production. Areas within Minnesota could hang on to snow and lowered ceilings longer toward 00Z. Expect TEMPO groups to be prevalent within TAFs until around this time. Additional light snow and lowered ceilings will move into eastern North Dakota into west-central Minnesota toward midday Thursday. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...None. MN...None. && $$ UPDATE...CJ/Riddle DISCUSSION...Riddle AVIATION...CJ
