Two separate storm systems will be moving into Southwest Montana over the next 2 days causing havoc on the roadways for travelers.
The first storm system will move in late tonight into Sunday morning. Most computer models indicate the possibility of 1" of snow in the valleys with slightly higher amounts possible in the mountains by Sunday evening.
A break in the snow comes in Sunday night, before another stronger system moves in for Christmas Eve, with a few inches of snow possible during the day on Monday. Most valley locations should expect 1-3" of snow, with up to 4" in the higher mountain areas. While this isn't a significant amount of snow, with many travelers out on the road for the holiday, play it safe on the roads, and expect slick conditions through Christmas morning.
Following this second storm, cold air will move in with lows expected to be well below zero Christmas morning, with highs throughout the rest of the week expected to be below seasonal.
