Winter Storm Warning (in pink on graphic below) is still in effect for portions of Central and North-Central Montana through 5 PM Sunday. Folks in these areas could see a storm total of 6"-12" (up to 20" in the mountains) by Sunday evening. In addition to the falling snow, winds could gust up to 35 mph creating difficult driving conditions and bitterly cold wind chills near -30.
Winter Weather Advisories (in purple) are in effect along the Hi-Line. These areas could get anywhere from 2"-4" of additional snow on the plains and 6"-10" of additional snow in the mountains by Sunday Evening. Again, winds could gust up to 30 mph causing bitterly cold wind chills as cold as -40.
A Wind Chill Advisory (in light blue) has been issued for portions of North-East Montana. These areas won't see as much snow as areas to the west, but wind chills will be bitter here as well prompting the advisory. Wind Chills could approach -40 in these areas as we head into Sunday. These advisories may spread in coverage as we head into the weekend for early next week as more arctic air invades the region.
It's important to remember that wind chills this cold can cause frostbite in as little as 10 minutes and are very dangerous if you become stranded in them. Make sure to bundle up and cover all exposed skin if you must be outside. Road conditions have also deteriorated with the snowfall we've had, so if you have to travel make sure you have an emergency kit with you. Be safe out there and we'll be here over the weekend online and on air to keep you updated.
