A strong low pressure center has moved over the Rocky Mountains and is causing a huge change in the weather across the High Plains. Temperatures have dropped in Montana and Wyoming nearly 15° – 20° in the last 24 hours and the significant amount of moisture associated with this system has transitioned to snow in the higher elevations.
Snow levels started around 7,000 ft. and will continue to lower around 5,000 ft. as temperatures drop overnight. Winter Weather Advisories and Winter Storm Warnings are in effect for parts of Montana, Wyoming, Idaho and Utah. Parts of the foothills could pick up 1 – 4” of snow and elevations above 6,000 ft. could see up to 12”. Periods of snow will continue throughout the day on Tuesday, accompanied by strong gusting winds. Heavy wet snow and ice could lead to difficult driving conditions on the roads.
