Area Forecast Discussion National Weather Service Glasgow MT 118 PM MST Fri Feb 28 2025 .DISCUSSION... KEY MESSAGES: - A Flood Watch remains in effect through Sunday for the Yellowstone River due to possible ice jams. - Temperatures remain well above normal through Sunday. - Temps cool to slightly above normal Monday onward due to a cold front with some light mainly snow precipitation Monday afternoon into Tuesday. WEATHER PATTERN OVERVIEW: Through Sunday, an upper ridge will move east across Montana as it weakens. This will allow for temps to remain above normal with dry conditions. Monday morning, a cold front will drop into the region from the NW allowing for cooler conditions. Temps will move closer to seasonal norms Tuesday, then gradually warm thereafter. Monday afternoon into Tuesday, a disturbance passing over the cold front will bring a small chance for precipitation with any rain quickly transitioning to snow. Liquid precipitation amounts will be less than a tenth of an inch with snow amounts less than an inch, except around Little Rockies of southwest Phillips county where maybe 2 inches might be possible. FORECAST CONFIDENCE & DEVIATIONS: No deviations were used this forecast cycle. TFJ && .AVIATION... LAST UPDATED: 2110Z FLIGHT CAT RANGE: VFR DISCUSSION: Mainly mid to high clouds will continue to stream into the area from the NW. MVFR/low VFR clouds however will back into some areas late tonight/early Saturday. WIND: W to NW winds calming to less than 10 kts and becoming variable this evening. Light S or SE winds (less than 10 kts) can be expected Saturday. TFJ && .HYDROLOGY... February 28th: The Flood Advisory is in effect for the lower Poplar River until Sunday afternoon. An ice jam and/or snowmelt is contributing to a high water level near Poplar, but it likely lower to the north as indicated by the river gauges along the Canadian border. The Flood Watch remains in effect for the Yellowstone River through Sunday as the potential still exists for minor flooding if an ice jam occurs. However, it appears that the greatest threat hs passed, so this Watch may be allowed to expire Sunday. TFJ && .GGW WATCHES/WARNINGS/ADVISORIES... Flood Watch through Sunday afternoon for Dawson-Prairie-Richland. && weather.gov/glasgow
