A strong cold front is expected to move through the region overnight into early Friday morning. This system will bring a few hours of moderate-to-heavy snow, gusty winds near 40 mph, and a notable drop in temperatures into the 20s. These conditions will lead to significantly reduced visibility to less than half a mile and slick roads from 4-10 AM. Travel may become problematic, especially on mountain passes and roadways above 4,500 feet. Specific routes of concern include Lost Trail Pass (US-93), Homestake Pass (I-90), Lolo Pass (US-12), and MT-1 (Philipsburg to Anaconda). While Marias and Homestake may not see the most snow, there will still be a threat for strong winds and low visibility.
