306 FXUS65 KMSO 140808 AFDMSO Area Forecast Discussion National Weather Service Missoula MT 208 AM MDT Mon Sep 14 2026 .DISCUSSION... KEY MESSAGES: - Widespread rain showers, high elevation snow and breezy conditions today - Drying and warming conditions by mid-week. - Trending wetter late Thursday into Friday. A low pressure system moving along the northwest Montana and Canadian border will slowly shift eastward today. This system is producing widespread rain showers across all of western Montana and north-central Idaho, with heavier showers focusing on northwest Montana and north-central Idaho today. Snow levels dropped to roughly 6,500 feet overnight, resulting in light snow accumulations from the Continental Divide southward to the Bitterroots. Additionally, breezy westerly winds will develop once again across western Montana, with gusts of 20 to 30 mph. Backcountry recreationists should prepare for cold, raw conditions and a heightened risk of hypothermia today. As the system exits by tomorrow morning, the region will experience a brief warming and drying trend through mid-week, though isolated showers may linger near the Canadian border. Clearing skies early Tuesday will cause temperatures to drop significantly, bringing chilly conditions to areas along and south of Interstate 90. Subfreezing temperatures are expected in the higher valleys of southwest Montana and along the Continental Divide, while frost will likely develop in the typically colder locations of the Missoula, Bitterroot, and Clearwater valleys. Forecast models indicate another low-pressure system will move inland from the Pacific coast Wednesday night, tracking across western Montana and north-central Idaho Thursday into Friday. This incoming system is expected to interact with abundant moisture from the south, leading to increasing precipitation and thunderstorm chances late in the week, particularly for areas south of Interstate 90. While a majority of forecast models (nearly 80%) support a wetter scenario, confidence regarding the exact timing and specific local impacts remains low at this time. && .AVIATION...Aviation operations across western Montana and north central Idaho will encounter degraded flight conditions today as a low pressure system tracks eastward along the northwest Montana and Canadian border. This system is generating widespread showers across all of western Montana and north-central Idaho, with the most concentrated precipitation, and highest probability for MVFR to localized IFR restrictions focusing over northwest Montana and north-central Idaho. With snow levels having fallen to near 6,500 feet MSL overnight, pilots should anticipate light high-elevation snow accumulations and widespread mountain obscurations. An increasing pressure gradient will promote breezy westerly surface winds across western Montana this afternoon, producing gusts of 15 to 25 kts. && .MSO WATCHES/WARNINGS/ADVISORIES... MT...None.
