795 FXUS65 KMSO 010756 AFDMSO Area Forecast Discussion National Weather Service Missoula MT 156 AM MDT Mon Jun 1 2026 .DISCUSSION... KEY MESSAGES: - Through Tuesday: A slow moving weather system will bring prolonged, light to moderate rainfall, focused along the divide and in Glacier Park region. - River, stream, and creek rises from widespread rain and snow melt, leading to the risk of minor flooding across northwest Montana. Satellite and radar observations this morning show a closed low remaining nearly stationary in central Montana east of the divide. Widespread rain continues north of I-90 and along and east of US-93 early this morning. Observations show the heaviest precipitation totals over the last 72 hours across Flathead and Lake Counties, where generally 1-2 inches has fallen in valley areas and 2-4 inches in the mountains. This rainfall, combined with snowmelt is leading to significant rises on small streams, creeks, and rivers. An elevated risk exists for minor flooding from small streams and creaks from the Mission and Swan Mountain ranges. Flood watches remain in effect for the Flathead River near Colombia Falls and Clark Fork above Missoula, with these river systems expected to peak later this evening into early Tuesday morning. Widespread rain will spread westward through the morning into the afternoon, reaching the Montana/Idaho border and I-90 corridor in west-central Montana. Precipitation rates will increase across Flathead and Lake Counties during this period, with valley areas seeing locally moderate rainfall. By the afternoon, widespread rain will transition into showers across the I-90 corridor and near the Idaho/Montana border as the low moves slightly north and east. By tonight into Tuesday morning, high resolution models suggest the low will wobble northwestward, bringing a return of widespread rain for all areas along and north of the I-90 corridor. Finally, the low will begin to move eastward Tuesday night into Wednesday morning as a Pacific trough moves onshore in the Pacific Northwest, introducing rising heights and building high pressure as we look ahead to Wednesday across the Northern Rockies. Snow levels will be 6,500-7,500 feet through Tuesday, with wet snow accumulating along the divide in northwest Montana. For those considering adventuring in the higher terrain, be prepared for cold and raw backcountry conditions. By the end of this precipitation event, valley areas along the US-93 corridor north of Missoula can expect another 0.50-1.00 inches of precipitation, with the higher terrain along the divide, including the Swan and Mission Mountains seeing another 1.00-2.50 inches. A quick warm up brings us back to normal temperatures or slightly above normal by Wednesday. Late Wednesday into Thursday and again Saturday into Sunday, could bring more unsettled weather producing showers and thunderstorms. More to come on the evolution of these systems; stay tuned! && .AVIATION...A large upper low will wobble around central Montana into Monday bringing periods of precipitation into the Northern Rockies. The heaviest precipitation will be north of I-90 and along and east of US-93, with mountain obscurations remaining common, and visibility and ceilings down to MVFR at times (infrequently to IFR) at KGPI and occasionally KMSO. Other terminal sites and across north-central Idaho will see lower precipitation chances and lesser aviation impacts. West to northwest winds of 15-20 kts will return this afternoon. && .MSO WATCHES/WARNINGS/ADVISORIES... MT...Flood Watch until noon MDT today for West Glacier Region. ID...None. && $$
