IDAHO FALLS — Bundle up! Another early-season winter storm will move into the northern Rockies Tuesday and Wednesday, bringing moderate snow, wind and a drastic 20-30 degree temperature drop as a strong cold front crosses the region Wednesday morning.
The National Weather Service reports snow accumulations Wednesday may reach 2-4 inches in the northern Central Mountains, 2-6 inches across the Upper Snake Highlands and Montana Border, and a dusting to 1.5 inches elsewhere across southeast Idaho.
An enhanced band or zone of moderate snow, reduced visibility, and slick roads is possible in the central or northern Snake Plain from mid-morning through mid-afternoon Wednesday.
Some areas may see a flash freeze Wednesday morning as the cold air pours in, making some wet and untreated roads icy.
