Montana has experienced a significant transition from unseasonably warm temperatures, with cities like Great Falls and Billings reaching the 70s, to colder and wetter conditions. 

Forecasts indicate an incoming system bringing rain to areas west of the Divide, spreading eastward. This shift is expected to bring snow to mountain passes and high-country areas, particularly along the Northern Divide above 6,000 feet, potentially creating slick driving conditions. 

In other regions, such as the Rocky Mountain Front and the Continental Divide, winter storm warnings have been issued for snow accumulations reaching 10 to 20 inches with wind gusts up to 45 mph. Local officials, including the Helena City Street Division, have prepared for these conditions by placing crews and plow trucks on standby to clear emergency routes.
