STORMTracker meteorologist Mike Rawlins says snow will continue to fall through Wednesday, resulting in an additional 3-5" of accumulation at lower elevations east of the Rocky Mountains.
Gusty winds on Wednesday will also create areas of blowing and drifting snow, leading to near whiteout conditions on Montana's highways.
Thursday will be a transition day for us as one storm system moves out and another approaches from the north.
Rawlins says a cold front diving south out of Canada late Thursday night will produce more snow heading into Friday and Saturday.
An additional 3-5" of snow is expected from this storm system, which will ensure Montana enjoys a white Christmas this year.
Following the cold front, very cold air will arrive, with high temperatures falling into the single digits above zero and morning lows dropping below zero through the weekend and heading into Christmas.
