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.

Frost is possible on Sunday and Monday mornings. Temperatures are expected to dip into the low to mid 30s across parts of western Montana and higher valleys of north-central Idaho early Sunday and again Monday morning. Tips: Cover outdoor plants overnight, and move potted plants indoors if possible.
