BOZEMAN – Next round of rain/snow and wind will roll into Idaho and Montana tonight into Saturday morning.
Colder air will dig into the region and lower snow levels to as low as 4,500’ by Sunday morning. Best chances for accumulating snow should be around 5,500’. Most, if not all, mountain passes will see periods of rain/snow Saturday afternoon and all snow by Saturday evening into Sunday morning.
Be prepared for wintry travel impacts this weekend with wet roads turning icy and could be snow covered at times with areas of blowing snow.
After this system moves out by Sunday afternoon several other pacific storms will pass through the state beginning Sunday evening through Wednesday of next week. Wintry travel impacts are likely as each system passes through the state especially for mountain passes both west and east of the divide.
