IDAHO FALLS — A strong low-pressure system will push into Central and Southeast Idaho Tuesday, spreading widespread rain and snow showers across the region.

The most persistent and impactful activity is expected from Tuesday afternoon through Wednesday evening, although lingering rain and snow showers may continue into Thursday evening.

Snow levels are expected to average 5,500 to 6,500 feet throughout the event, lowest during the colder late night/morning hours and highest during the warmer afternoon hours. One inch of snow or more is expected above 6,000 feet, with 3-8 inches above 6,500 feet. This will result in hazardous travel conditions across most of our mountain highways and passes/summits. 8-12 inch totals cannot be ruled out above about 7,500 feet, which is above our mountain passes and highways.

High likelihood:

– Accumulating snow showers across the Central Mountains, Island Park region, Teton Valley, Caribou Highlands, Bear Lake region, and higher peaks/ridges in the Southern Highlands.

– Rain showers across the Snake Plain and other valley locations.

Low likelihood:
