A weak ridge of high pressure will set up across this region. This means dry skies as our next weather makers begins to advance into the region. Snow showers will arrive late Tuesday and into Wednesday. During this time frame, the Flathead and Mission valleys will see up to 4 inches of snow. Snow may transition to rain during the day Wednesday as high temperatures are expected in the mid to upper 30s.
WINTER WEATHER ADVISORY from 5 PM Tuesday to 5 PM Wednesday for the Kootenai/Cabinet Region. Total snow accumulations of 2 to 5 inches possible for Libby, Eureka and Stryker. Localized higher amounts in extreme northwest Montana near the Yaak region. The worst conditions will be around the Wednesday morning commute for the advised locations.
WINTER WEATHER ADVISORY is also posted for the Lower Clark Fork Region. Total snow accumulations of 2 to 5 inches in Plains, Thompson Falls, and Trout Creek. Localized amounts up 10 to 12 inches in the mountains including Lookout Pass, are expected. Lookout Pass will experience the worst of the conditions with brief periods of heavy snow and low visibility Wednesday morning.
The daily threat of snow will continue with another round of snowfall occuring area-wide Thursday as a cold front will move through and allow temperatures to fall slightly as well. It does not appear this system will bring heavy accumulations to any valleys, but light accumulations are likely across all western Montana valleys.
Moisture will continue to stream in from the Pacific Friday and Saturday, allowing for continued chances of snow. It appears the heaviest accumulations will occur in west central and NW portions of the state.
