Advisories and warnings posted for incoming snowfall
A WINTER WEATHER ADVISORY has been posted for portions of west central and southwest Montana. It includes the Missoula and Bitterroot Valleys. the Butte/Blackfoot region, and the Lower Clark Fork region. The advisory lasts from 11PM tonight until 5PM Sunday, and those included can expect to receive 1 to 4 inches of snowfall.
A WINTER WEATHER ADVISORY has been posted for Madison and Gallatin counties from 5AM Sunday to 5AM Monday for 2 to 5 inches of snow below 5500 feet. A WINTER STORM WARNING has been posted for the same area for 6 to 12 inches of snow above 5500 feet.
Snow and Valley rain will start affecting portions of western Montana Saturday evening before transitioning to all snow Sunday morning. Most area mountain passes can expect to receive anywhere from 4 to 8 inches of snowfall. Travel on these passes will become hazardous starting Saturday night and continuing through Sunday.
Snow will continue through Sunday afternoon, possibly mixing with some rain in the lower valleys. It will move out of the area early Monday.
A change in the weather pattern will occur next week as strong high pressure builds over the region. This will allow for dry conditions and plenty of sunshine. It also will allow for daily chances of morning valley fog.
