warmer air moves back into the area later Thursday afternoon.

Thursday through this weekend, multiple embedded short-wave
disturbances from the Canadian Rockies will bring repeating
chances for snow across NE Montana, with details still a bit
unclear. At this time, model data continue to indicate that winter
weather impacts will be minimal. Stay tuned for more updates.
