IDAHO FALLS — A winter storm is heading toward eastern Idaho this weekend.

The National Weather Service has issued a winter weather advisory for the following counties: Clark, Teton, Fremont, Madison, Bonneville, Jefferson, Bingham, Bannock, Onieda, Caribou Franklin and Butte. Up to 3 inches of snow are predicted in the region between 5 a.m. and 5 p.m. Saturday.

Higher amounts of snow are expected in the mountain passes and near the Wyoming border. Additionally, Fremont, Clark and Teton counties are expecting up to 6 inches of snow across the area.

The heaviest snowfall is expected between 5 a.m. and 11 a.m. Saturday morning.

Similar winter weather conditions are expected in southern Montana.

Air quality advisory

An air quality advisory remains in effect in Franklin County due to elevated pollutant levels in the air. A stable atmosphere with little wind is preventing pollutants from drifting outside the area. As a result, residential wood burning restrictions have been put in place inside the county until at least noon Saturday.

Individuals with inherent sensitivity to increased particulate levels are encouraged to avoid prolonged physical exertion outside. At these levels there is an increasing likelihood of respiratory symptoms and increased aggravation of asthma and/or lung ailments, according to NWS officials.
