WINTER WEATHER ADVISORY for Lost Trail, Lolo, MacDonald, and Homestake Passes for a slushy 1 to 2 inches of snow. Showers will begin as rain early Tuesday morning, but will change over to moderate snow by Tuesday afternoon. The Tuesday evening commute will see the biggest impacts with snow and reduced visibility.
Don't expect temperatures to warm much if at all as we move through the day as cool air invades from the northwest. Expect valley rain showers across the entire region with the Bozeman area seeing showers later in the day than the rest of us. The longer wait for rain will also help the Gallatin Valley reach close to 60 degrees. Elsewhere expect highs right around 50 degrees. Snow levels will drop throughout the day to below 6000 feet near the divide. Skies clear Tuesday night.
Areas of fog will impact the Wednesday morning commute with morning lows in the 30s. Expect a dry day on Wednesday with highs in the mid to upper 50s. Late Wednesday night rain showers will again appear around Northwest Montana and bring rain on Thursday to areas west of the Continental Divide. Cool weather continues into the upcoming weekend.
