From an AP story by Amy Beth Hanson headlined “First major snowstorm of the season hitting the northern Rockie after a warm fall”:

The first major snowstorm of the season is expected to hit the northern Cascades, Rockies and North Dakota this week, sending residents searching for their winter coats, gloves and boots and facing much different driving conditions after a warm fall in many places.

The National Weather Service is warning of hazardous travel on snowy mountain passes and ice on some highways when snow initially melts and then freezes as road temperatures drop.
