591 FXUS63 KMPX 191951 AFDMPX Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 151 PM CST Wed Nov 19 2025 .KEY MESSAGES... - Patchy drizzle and fog overnight, but surface temperatures will remain above freezing so no impacts from icing expected. - Mild with slightly above normal temperatures and no significant precipitation chances into early next week. - Cooler temperatures arrive Tuesday and last through the Thanksgiving Weekend. && .DISCUSSION... Issued at 132 PM CST Wed Nov 19 2025 Today and Tonight...Visible satellite imagery together with surface obs showed cloudy skies across the region, with a few lower visibilities due to some lingering fog and light mist. This trend will continue overnight as a weak pressure trough moves across the region, so have continued with a chance for drizzle and fog overnight as the forecast soundings show low level saturation and weak lift. Fortunately surface temperatures will be in the mid-30s, so not anticipating any impacts from icing. Thursday through Sunday...On Thursday, winds will become northwest as the surface trough passes through, which will clearing skies from west to east, and perhaps a few peeks of sun by Thursday evening. High pressure will settle in, and for the most part remain in control as the Upper Midwest is sandwiched between the northern stream storm track across Canada, and a cutoff slow over the desert southwest. This will keep the region dry and mild through early next week. Monday through the Thanksgiving Weekend...Looking ahead, on Monday the cutoff low will slowly migrate eastward, while a potent shortwave trough moves over the Pacific Northwest. How these two features interact will determine the weather across the Upper Midwest. For example, if the southern stream upper level low kicks out farther north and slower, that will lead to a more northerly track for the shortwave trough, and any snow associated with it will fall across Canada. If that shortwave trough is faster and farther south, then it could dig across the Upper Midwest, bringing cold air and accumulating snow across the northern half of Minnesota and Wisconsin on Wednesday into Thanksgiving morning. Needless to day, anytime a cutoff low is involved, the forecast confidence decreases. So for that reason, not leaning towards any one solution at this point with regards to chances of snow. One thing that is more certain is the idea that cold air will follow for the middle of next week, and should last through the weekend. For now, we`re looking at highs in the upper 20s to low 30s, with lows in the teens or single digits. So it will be cold, but as of now, not expecting it to be hazardous. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/... Issued at 1114 AM CST Wed Nov 19 2025 MVFR to borderline IFR cigs are expected through the period. Things trend more IFR overnight with some fog/drizzle possible by early morning. Thursday morning looks to be much like this morning with improvement coming just beyond the end of the forecast period. Winds are southerly but will turn out of the west to northwest by tomorrow morning. KMSP...Expecting cigs to lift to MVFR this afternoon before falling again late tonight. There`s a chance for some drizzle early tomorrow morning, but uncertain whether or not it would impact vis, so have left it out for now. Conditions begin to improve by tomorrow afternoon, but have opted to remain MVFR through the end of the period. /OUTLOOK FOR KMSP/ FRI...VFR. Wind W 5kts. SAT...VFR. Wind SW 10-15 kts. SUN...VFR.
