Area Forecast Discussion National Weather Service Glasgow MT 231 PM MST Fri Jan 31 2025 .DISCUSSION... KEY MESSAGES: - One more day of above normal temperatures, then Winter makes a return with below normal temps and occasional snow. - A strong Arctic cold front will move in Saturday night dropping temperatures to well below normal for most of next week. - Expect a period of snow, some of it significant south of Fort Peck Lake, beginning late Sunday. WEATHER PATTERN OVERVIEW: Large upper trough over the Gulf of Alaska is moving into western Canada this afternoon with lots of moisture streaming northeast ahead of it. A surface low will form over southern Alberta Saturday morning then move east during the day. This will allow warmer air to push east across northeast Montana on strong west winds. An arctic airmass will then spill in Saturday night and will not leave the area through the forecast period, if not through about the middle of February. Long term models are showing an atmospheric block occurring with a very strong upper ridge over Alaska and a ridge over the deep south, holding the upper trough nearby and keeping Montana in the grips of the cold for awhile. Otherwise, freezing rain chances look minimal at this point, with maybe a few drops late tonight near Sheridan county. Mainly dry conditions then are expected until the SW to NE moisture stream sets up over an arctic boundary beginning late Sunday. Over 6 inches of snow is possible south of Fort Peck Lake and in the Little Rockies through Wednesday. Highlights may be tricky as this will be falling over such an extended period of time. Stay tuned to our webpage as updates will be occurring with this event. TFJ FORECAST CONFIDENCE & DEVIATIONS: - Winds tonight through Saturday were blended with NBM90. - Freezing Rain possibilities have lowered for tonight and Saturday night. - QPF and thus snow amounts were raised slightly with this package for the period Sunday night through Wednesday. But alterations will likely be made as we draw closer to this event. && .AVIATION... Updated: 2130z. Flight Category: MVFR (except KGDV) becoming VFR by 06z. Low clouds will lift NE this evening but not exit the area. Airports such as Plentywood will continue to experience IFR/MVFR ceilings/conditions through Saturday morning. Winds: ESE winds will diminish tonight then turn West and increase while turning slightly to the NW Saturday night. Outlook: Prolonged active weather is expected to move in late Sunday that could linger into Wednesday. TFJ && .GGW WATCHES/WARNINGS/ADVISORIES... None. && weather.gov/glasgow
