BUTTE – Long holiday weekend is here! The travel weather patterns will be changing over the next 4 days. There will be some good travel weather but there will be some wintry travel impacts as well.
Here is the break down: Thursday looks good for most of SW Montana, however, a weak pacific system will bump up against the MT/ID state line throughout the day and produce scattered snow showers and increasing surface winds. Best chance for accumulating snow will be those mountain passes on the state line.
Friday: The next and stronger pacific storm will begin to influence travel across the entire region (Pacific NW into the central & northern Rockies). Stronger cold front will produce stronger surface winds and increasing snow showers. Snow showers should be widespread but mostly on the lighter side between Butte-Bozeman-Dillon. Hoever, there will be areas of moderate snowfall in SW Montana especially around West Yellowstone.
Saturday: Morning snow showers will continue for most areas along with windy conditions. Saturday morning will likely by the worst travel time across SW Montana with most mountain passes picking up snow, cold and wind Friday night leading to icy roads Saturday morning.
Sunday: We begin to dry out but colder air will be digging into the state and temperatures will drop below normal. Travel weather should be improving but watch for icy roads especially at pass level.
