FYI…

Heavy snow possible next 12 to 72 hours parts WA, ID, MT, WY, ND and in western MN by Friday.

Up to 0.26” of ice accumulation is forecast over next 24 hours in parts east-central MT and west-central ND. The current SPIA Index Ice Impact forecast for those areas is at Level 1, meaning the combination of ice accumulation and wind speeds could cause some scattered power outages in east-central MT and far west-central ND next 24-hrs.
