002 FXUS65 KGJT 250805 AFDGJT Area Forecast Discussion National Weather Service Grand Junction CO 105 AM MST Tue Nov 25 2025 .KEY MESSAGES... - Temperatures fluctuate from near normal to above normal by late in the workweek. - Other than some mild snow showers in the northern mountains conditions remain dry for most locations this week. - A stronger weather system could impact holiday travel across the Intermountain West this weekend with wintery conditions in the mountains. && .SHORT TERM /THROUGH WEDNESDAY/... Issued at 101 AM MST Tue Nov 25 2025 The potential for light snow showers over the northern Colorado mountains throughout the remainder of tonight has dwindled significantly. At the absolute best, the highest elevations have about a 25% chance of seeing any snowfall through sunrise. Many CAM`s are on board with this trend as well. Though some modest moisture still appears to be residing over these areas as seen in satellite imagery, the cold front passing through just hasn`t been strong enough to prompt any showers. Moisture does jump back up tomorrow though, and with northwesterly flow still in place, we could have a better shot at seeing measurable snowfall beginning Wednesday night. Even so, it`s highly unlikely (<35% chance per NBM) that we will see any more than a couple inches of accumulation, the majority of which would be confined to mountain passes and higher elevations anyways. && .LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/... Issued at 101 AM MST Tue Nov 25 2025 We remain under a northwesterly flow regime through late in the week with seasonal to slight above normal temperatures and mostly dry conditions. Periodic flurries are possible over the northern mountains at times due to favorable orographic lift, but measurable snow is not anticipated at this time. Attention then turns to an active pattern that is expected to develop over the western CONUS this weekend. It could start as early as Friday as chances are increasing for a clipper system in northwest flow. This could bring precipitation to the northern and central mountains. On Saturday the ensembles show the next piece of energy trying to cut off from the main flow somewhere over the region. Regardless of what that low does the main trough will push a cold front through our CWA. It looks like the low pressure will provide the moisture to produce precipitation. There is a potential for snow levels to reach the lower valleys, which means wintery conditions for the mountains. As of now Sunday has the highest chances for widespread precipitation, but that could change. This system could cause impacts to the holiday travel expected so stay tuned as we refine the timing and details. && .AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/... Issued at 956 PM MST Mon Nov 24 2025 Low stratus will hang around KDRO, KASE and KHDN overnight with potential for fog at KDRO so kept low CIGS through 18Z. Conditions will be MVFR at times due to low CIGS and potentially IFR where fog occurs. Otherwise, VFR should prevail outside of low stratus areas with improving conditions by Tuesday afternoon. Winds remain light and terrain driven. && .GJT WATCHES/WARNINGS/ADVISORIES... CO...None. UT...None. && $$ SHORT TERM...BW LONG TERM...KJS AVIATION...TGJT
