593 FXUS63 KMPX 301726 AFDMPX Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 1126 AM CST Tue Dec 30 2025 .KEY MESSAGES... - Two clippers will bring minor snow accumulations today and Wednesday. - Cold start to the New Year, with sub-zero morning lows and highs in the single digits. Temperatures modify back into the 20s next weekend. && .DISCUSSION... Issued at 308 AM CST Tue Dec 30 2025 Clouds have increased overnight ahead of today's clipper system. The increased cloud cover and weak warm air advection have allowed temperatures to slowly rise overnight. A warm front across western MN will continue east this morning. Temperatures will rebound back into the low 30s for highs by late this afternoon/early this evening across MN. The clipper will track from southern Manitoba early this morning to northern WI this afternoon. A period of light snow will accompany the system this morning and could bring accumulation of around an inch to areas along and east of the Mississippi River. The light snow will end as the DGZ layer dries this afternoon, but continued saturation from just above the surface to about 8kft and very weak Omega throughout the layer may allow areas of light freezing drizzle to develop. Any freezing drizzle that develops will end late in the afternoon as the saturated layer becomes shallower. Quick on the heels of the first clipper, a second one will track from Alberta this evening to Nebraska midday Wednesday. More light snow will spread southeast, but this time a little farther southwest. Slightly higher snow ratios are expected to offset the lighter QPF. There will be two DGZ layers, one between 10-15kft AGL, and the second from the surface to 5kft AGL thanks to a renewed shot of arctic air. However, lift will be weak and winds will be very strong in the upper level DGZ which should fracture the dendrites. Steep low level lapse rates will reside within the lower DGZ, potentially allowing for steadier snow showers at times. All that being said, it should be another few hour event that leads to around an inch of accumulation. The longer range pattern into early next week will feature a ridge across the western U.S. and a trough in the northeast. Like the next couple days, there may be a couple weak clippers passing through capable of brief periods of light snow or flurries. There are no larger storms on the horizon. Temperatures will generally remain below normal, but a rebound toward normal may occur Sunday and Monday as the pattern flattens out a little and we're able to build in slightly milder air. && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1126 AM CST Tue Dec 30 2025 Light snow has been tracking across central Minnesota into western Wisconsin this morning and will continue into the afternoon. As this snow has been coming to an end some patchy freezing drizzle has been observed. This will continue to be possible this afternoon into the early evening. Lower MVFR ceilings to continue into tomorrow as another clipper system arrives. This should provide another round of light snow. Exact timing of the biggest impacts still a little uncertain, so opted for a larger PROB30 that we will refine in future TAFs. MVFR most likely with this snow but more isolated IFR as well, as seen this morning. Main difference for tomorrow is that the snow will track a little farther south and be more impactful for STC, MSP, and MKT. KMSP...Generally expecting the light snow with MVFR impacts to continue early this afternoon. There could be some freezing drizzle at the end of the snow, but it appears brief such that it was not added to the TAF. Also the worst of the snow has remained to the northeast, so kept the IFR TEMPO out. MVFR continues through tomorrow with another round of snow tomorrow morning. /OUTLOOK FOR KMSP/ THU...VFR.
