A WIND CHILL WARNING in effect tonight through Saturday for the following counties: Flathead, Sanders, Lake, Lincoln, Missoula, Mineral, Ravalli, Granite, Powell, Deer Lodge, and Silver Bow.
Strong winds above 20 mph may push wind chill values between -20° and -30°.
With these cold conditions, frostbite and hypothermia will come quickly to people exposed outdoors. Livestock and pets should be moved inside or under shelter from the wind. If you must venture outside, make sure to cover exposed areas and keep extremities warm.
Additional snow is expected across the region today. This will mostly be a mountain event. However, light accumulations are possible in the valleys of southwest Montana. The snow will be very dry and powdery, and will primarily pose a visibility risk due to high winds expected over the next couple of days.
The replenished cold air will make for a very cold weekend before winds shift to bring us moist pacific air from the west. While temperatures will warm above zero, they will still be well below average. The odds of seeing snow will slowly increase as we go through next week as well.
