WEATHER DISCUSSION: Dense freezing fog continues to impact the Hi-Line as an inversion holds moisture and colder air closer to the ground. The fog will create slick travel and reduced visibility the next several days.
Periods of light snow, potentially mixed with light freezing rain, will begin to impact north central Montana overnight. While accumulation are expected to remain under an inch for lower elevations, there will be icy spots on Monday morning. Higher elevations throughout central and southwestern Montana can expect 1-4" of accumulation by Monday evening.
The weather is going to remain unsettled across the northern Rockies and high plains this week, however there are still no major storm systems anticipated in the next several days. A trend towards cooler temperatures is expected for late January.
