A parade of storms will be moving across the Pacific Northwest over the next several days.
This series of storms will bring a carving of cold air that will push across much of the inter mountain west by Tuesday and Wednesday allowing for freezing levels to drop for parts of the mountains of Montana and Wyoming just in time for Halloween
The waves of moisture will result in light to moderate accumulations of snow over the next several days so not all at once. Accumulations could result in a half of foot or more for elevations above 6,000 feet beginning Monday and extending through Wednesday evening.
So bundle up! And layer up under those costumes.
