NWS Glasgow, MT wrote its last area forecast discussion before the first event at May 31, 12:45 PM MST, 11 hours 15 minutes earlier.
Area Forecast Discussion National Weather Service Glasgow MT 145 PM MDT Sat May 31 2025 .DISCUSSION... KEY MESSAGES: - A cold front will drop southeast through the area Sunday bringing breezy to windy conditions to the area. - Showers and isolated thunderstorms move in late Sunday, but thunderstorms generally should be below severe limits. - Much cooler conditions expected Monday WEATHER PATTERN OVERVIEW: Smoke from wildfires in central Canada moved a little further east than expected. Visibilities dropped to about 8 miles from Plentywood to Sidney while much lower visibilities were reported over western North Dakota (as low as 1 1/2 to 3 miles). Cooler conditions over central Canada looks to have diminished the fires a bit today but minor areas may drift in occasionally from northern Alberta fires the next few days. The next weather-maker is a cold front. That front was dropping through the Edmonton area in Alberta and is expected to reach the western zones Sunday morning and the eastern zones early Sunday afternoon. Daytime fronts lately have come in a bit stronger than what models suggested, so issued a Lake Wind Advisory for Sunday from 8 am till 10 pm. Thereafter, instability over SW and south-central Montana looks to generate showers and thunderstorms early Sunday afternoon. Some of these look to be strong but those should not reach our CWA. Instead we should receive more showers that spread northeast into the central zones Sunday evening. Rainshowers diminish by Monday afternoon with the southwest zones expecting to pick up the most, with over a half inch. Clouds and lingering showers will cool things off quite a bit Monday with highs up to 30 degrees cooler than Sunday. The upper trough will linger over the area through the week, but weaken into more zonal flow. This pattern favors seasonable temperatures with occasional isolated showers. FORECAST CONFIDENCE & DEVIATIONS: There is moderate to high confidence that NW winds in the wake of the cold front Sunday will be stronger than NBM. This looks very similar to what happened yesterday, so blended in higher model numbers to going forecast grids. The rest of the forecast generally followed close to NBM numbers. TFJ && .AVIATION... LAST UPDATED: 1945Z FLIGHT CAT RANGE: VFR DISCUSSION: A cold front over Alberta this afternoon will continue marching SE and arrive at KGGW about 12-15z. Look for winds to switch and increase behind the front from the NW with gusts to around 30 kts in the afternoon. High and some mid clouds will increase and thicken gradually into Sunday. Outlook: MVFR conditions are possible early Monday with rainshowers and/or low ceilings mainly in the KGDV area. TFJ && .GGW WATCHES/WARNINGS/ADVISORIES... Lake Wind Advisory from 8 AM to 10 PM MDT Sunday for Central and Southeast Phillips-Central and Southern Valley-Garfield-McCone- Petroleum. && weather.gov/glasgow
