552 FXUS65 KMSO 140823 AFDMSO Area Forecast Discussion National Weather Service Missoula MT 123 AM MST Fri Nov 14 2025 .DISCUSSION... KEY MESSAGES: - Breezy Today: Southwesterly wind gusts of 20-30 mph expected in the valleys and 40-50+ mph possible along the ridgetops and near the Continental Divide (especially the Glacier Park region). - Cooler Next Week: A pattern change early next week will finally bring in cooler air, lowering snow levels. This will reintroduce a chance for mountain snow and possibly a rain/snow mix in the valleys. Temperatures overnight have remained quite warm, with most of the valleys in the upper 40s to mid-50s at 1:00 am MST. These overnight lows are actually warmer than the expected afternoon high temperatures. This is due to showers and cooler air arriving with today`s cold front. With snow levels remaining high (above 7,000 feet), this will be a rain event for all but the highest mountain peaks. The primary hazard today will be wind. Strong southwesterly winds along the ridgetops and through wind-prone areas (like the high terrain of Glacier National Park) could gust over 50 mph. Most of the valley gusts are more likely to be in the 20-30 mph range, except for the Butte/Blackfoot region where gusts of 40-50 mph are expected. Looking ahead to next week, the stormy pattern continues. While the exact timing is uncertain, forecast models show a general trend toward a cooler, more seasonal pattern. A "parade" of weaker systems will move through, and as they do, they will draw in cooler air, gradually lowering snow levels. This will increase the chances for accumulating snow over mountain passes and reintroduce the possibility of a rain/snow mix on valley floors by Tuesday or Wednesday. && .AVIATION...Showery and breezy conditions are expected today as a cold front moves through the region. Strong southwesterly ridgetop winds of 40-50 knots will create a significant risk for strong, rotating turbulence (mountain waves), especially near and east of the Continental Divide. Freezing levels are unseasonably high, remaining near or above 7,000 feet (Mean Sea Level) through most of today. This will result in rain showers at all airports, leading to lowered ceilings and periodic lowered visibility. Mountains will likely be obscured by clouds. Freezing levels will begin to lower slightly over the northwest late this afternoon, dropping to around 5,000 feet. Breezy southwesterly winds will continue through tonight. && .MSO WATCHES/WARNINGS/ADVISORIES... MT...None. ID...None. && $$
