IDAHO FALLS – Bundle up, because a snowstorm could impact your community this weekend.

The National Weather Service in Pocatello is issuing a winter weather advisory in effect Sunday evening through Tuesday. An “upper level low” with much colder air will sweep across the region late Sunday night and will impact the areas of Island Park, Kilgore, Spencer, Edie School, Small, Monida Pass, Raynolds Pass, and Targhee Pass.

Lower elevations will see mostly rain but heavy snow is expected in the mountains.

Then on Monday, most of the Snake River plain will be affected, with up to an inch of snowfall in the areas of Jackson, Driggs, Rexburg and stretching south all the way to Malad. Several inches of snow are expected in and around West Yellowstone, Island Park, Lima, Leadore and Challis.

“Central Mountains and along the Montana Divide are likely to see all snow with accumulations 6-12 inches above 6,000 feet,” meteorologists with the NWS say. “Higher elevations will see gusty winds, potentially contributing to possible blowing and drifting snow.”

Winds could gust as high as 35 mph.

Other areas of impact include Howe, Arco, Mackay, Chilly, Borah Peak, Challis, Clayton, Stanley, Ketchum, Sun Valley, Galena, Copper Basin, Hailey, Bellevue, Picabo, Galena Summit and Willow Creek Summit.

The NWS is forecasting colder temperatures throughout eastern Idaho as the week progresses.
