Snow Impacts into this Weekend

A low pressure system will bring widespread snow and areas of winter driving conditions across northwest Montana and across mountain passes along I-90, US-12, and US-93 corridors Saturday into Sunday.

Other solutions show the cold air moving in faster, with a 30% for snow down to valley floors by Saturday morning. Stay tuned for further updates!
