NWS Glasgow, MT wrote its last area forecast discussion before the first event at Sep 9, 1:29 PM MST, 10 hours 31 minutes earlier.
Area Forecast Discussion National Weather Service Glasgow MT 229 PM MDT Mon Sep 9 2024 .DISCUSSION... KEY MESSAGES: - Hazy skies with occasional reduced visibility due to wildfire smoke through Tuesday. - Chances for rain will increase from Tuesday night through Friday, but with little accumulation expected. WEATHER PATTERN OVERVIEW: Flattening upper ridge and increasing westerly flow is bringing smoke from Idaho and Oregon wildfires into the region with some reduction in visibility possible overnight. A cold front dropping out of Canada on Tuesday will push the smoke southward, and bring cooler air southward. Flow aloft turns to the SW Tuesday night ahead of an upper trough moving inland from the Pacific. This will bring increasing moisture into the forecast area with chances for showers at times. The upper trough becomes an upper low over the Pacific NW Wednesday night and moves slow NE across west and central Montana between Thursday and Friday with differences in the models and ensemble on how quickly the system moves. While the NBM has frequent chances for precipitation, eastern Montana will also be frequently dry slotted in an unstable airmass which will limit precipitation to convective showers. FORECAST CONFIDENCE & DEVIATIONS: With the cold air advection behind the cold front on Tuesday, expect increased winds on Wednesday. These winds may be strong enough for a lake wind advisory, but currently strongest winds are indicated for the eastern counties, for marginal winds in the area near the dam and weaker winds to the west. There is low confidence on temperatures between Wednesday and Friday as ensembles have a large temperature spread across the region. && .AVIATION... VFR most of the time with occasional MVFR overnight as smoke from wildfires will moves in from the west. Another cold front will push the smoke south on Tuesday. && .GGW WATCHES/WARNINGS/ADVISORIES... None. && weather.gov/glasgow
