Winter storm winds down

Montana's 3-day winter storm is finally coming to an end after dumping 4 feet of snow in some areas.

The highest snow total comes from near St. Mary, along the Rocky Mountain Front, where 48" of snow was recorded.

Snow is still falling in some parts of the state, but the storm is expected to finally come to an end overnight.

An additional 1-2" of snow is expected along Interstate 15 and into the Northern Rockies through Sunday morning, but most of north-central Montana is finished with accumulating snow.

The Montana Department of Transportation is reporting severe driving conditions on some highways, so drivers are urged to use extreme caution before venturing out onto the roads.

Dangerously cold temperatures

It's already brutally cold out there, but even colder air will move in overnight.

Temperatures are expected to bottom out near -10 to -35° on Sunday morning, which will come close to breaking records in some cities.

As if that's not enough, 5-10 mph winds will push wind chills down to dangerously low levels.

STORMTracker meteorologist Mike Rawlins says it will feel like -45° in some places.

Wind chills this low can result in frostbite and hypothermia within 30 minutes.

If you're venturing out into the cold, you're urged to cover any exposed skin and dress appropriately.
