Today's Forecast:
Wind Chill Warnings have been issued for Butte, Anaconda, and Deer Lodge starting Wednesday night at 10 PM through Noon Thursday. We are expecting to see wind chill values in these areas approach -30° as the heart of the arctic air settles into southwest Montana. Highs for the region will be a mix of singe digits, teens, and 20s with a few flurries possible from Butte to Bozeman tonight.

BOZEMAN: High: 8; Low: -16. Mostly sunny and cold. Wind chill values could be near -15° to -20° at times. There is a slight chance of flurries tonight with little accumulation expected.

BUTTE: High: 18; Low: -14. Mostly sunny early with clouds for the afternoon. Light flurries are possible later in the day with extreme wind chill approaching -30° tonight.

DILLON: High: 18; Low: -14. Cold but sunny for your morning with more clouds for the afternoon.

WEST YELLOWSTONE: High: 20; Low: -4. Cold with a mix of sunshine and clouds by the afternoon.

Late Week Snow Chances: While arctic air is in place across most of Montana, we are also looking at a moisture-packed low pressure system hitting the California coast which will provide the potential for snow across Idaho and extreme southwest Montana by Thursday and Friday. With the cold air in place we can expect that moisture to overrun the cold air and provide snow across the southern tier of Montana. Models are typically indicating as much as 2”-4” inches of fresh snow for the Bozeman area and 4”-6” of snow for Butte and Anaconda by Friday morning. Expect frigid conditions to stay in place through Saturday with slick roads and dangerous wind chills through that time.
