Widespread valley rain and mountain snow across the Northern Rockies this weekend thanks to a seasonably-cold closed low moving through the region. Temperatures will be much cooler compared to recent (even compared to historical records for this time of year). Hazardous backcountry and road travel is likely in high elevation terrain.
A cold low pressure system will bring snowfall to the higher elevations of Glacier National Park this weekend. Snow levels will lower to around 5000 feet (possibly as low as 4000 feet) Saturday evening into Sunday, bringing accumulating snow to the backcountry, including over the higher portions of Going to the Sun Road. Difficult backcountry conditions are anticipated for recreation due to low visibility and snow-covered ground. Much colder temperatures combined with the wet conditions will cause a heightened risk of hypothermia. In addition, heavy rain in the lower elevation may cause rock and debris slides.
