942 FXUS65 KBOU 262347 AFDBOU Area Forecast Discussion National Weather Service Denver/Boulder CO 447 PM MST Mon Jan 26 2026 .KEY MESSAGES... - Warmer and dry through Wednesday with gusty winds over the higher terrain. - Good chance of light snow in the mountains late Wednesday into Thursday. - A shallow cold airmass may backdoor into northeast Colorado on Friday with a chance of light snow over the far northeast plains. && .DISCUSSION /Through Monday/... Issued at 131 PM MST Mon Jan 26 2026 Mainly dry NW flow aloft will remain over the area thru Tue night. Temperatures will continue to warm, except in the lower valleys over the higher terrain and along the South Platte River valley where inversions will be hard to break due to snow cover. Thus have lowered temps at least 10 degrees from guidance for tonight`s lows and Tuesday`s highs. Winds will be gusty at times over the higher terrain and near the foothills both tonight and again Tue night, however, speeds will not meet high wind criteria. On Wed, an upper level ridge will build into the area ahead of a weak upper level trough that will move across Wed night into Thu. Ahead of this feature it will be dry with temps slightly above normal across the plains on Wed. Once again, snow cover may alter highs in the lower valleys over the higher terrain and along the South Platte River valley. For Wed night into Thu the upper level trough will move across the area. Cross-sections show there will be enough moisture for mainly light snow in the mtns. Across the plains it will remain dry with seasonal temperatures. On Fri, NNW flow aloft will be over the area behind the upper level trough. Cross-sections don`t show much moisture in the mtns so snow chances will be low. Across the plains, the ECMWF continues to show a shallow layer of cold air backdooring across much of nern CO while the GFS isn`t as strong with this airmass. For now, have kept the coldest air over the far nern plains but it could easily spread much further west. Meanwhile, there will be a decent upper level jet over nern CO as well. Thus can`t rule out a chc of light snow over the far nern plains in the vicinity of the jet. On Sat, the flow aloft will become more NW. The shallow cold airmass is fcst to erode by the ECMWF while the GFS has it remaining over the far nern plains. For now will go with the blended solution and have it eroding as the ECWMF shows. On Sun, both the ECMWF and GFS have dry NW flow aloft over the area with above normal temps. && .AVIATION /00Z TAFS through 00Z Wednesday/... Issued at 438 PM MST Mon Jan 26 2026 VFR conditions are expected through this TAF package. Wind gusts have started to weaken at KBJC. West winds are expected to continue for the next few hours, before they begin to turn more SE. KBJC will have the potential for occasional wind gusts from the west around 20kts overnight. Winds will turn more westerly for Tuesday morning, before winds start to increase out of the WNW for the afternoon at KBJC. Winds at KDEN and KAPA will be more light and variable this evening, with SSW winds overnight. We could see a couple of hours of variable winds in the late morning as winds turn more to the NW for the afternoon. Tomorrow afternoon we could see wind gusts around 20kts from the NW at KDEN and KAPA, but confidence is low at this time. && .BOU WATCHES/WARNINGS/ADVISORIES...
