First Alert Weather: Rain and mountain snow threaten Halloween weekend
- A Pacific storm could bring rain to southwest Idaho and southeast Oregon Saturday, Oct. 31, through Sunday, Nov. 1.
- Rain is most likely Saturday evening and overnight; snow levels may fall to 4,500 feet Sunday.
- Above 6,500 feet, snowfall could reach 2–5 inches, with locally up to 7 inches on the highest peaks.
- Rain, reduced visibility, and slick mountain roads could disrupt Halloween plans and weekend travel, though this is not expected to be a major storm.
Detailed Summary
Rain chances increase Saturday afternoon as a cold front approaches, with the best chances Saturday evening and overnight. On Sunday, falling snow levels could bring snow or a wintry mix to elevations as low as 4,500 feet, though little accumulation is expected at lower mountain elevations as precipitation tapers off. The forecast advises having a rain backup for Halloween activities, bringing weather-appropriate gear, allowing extra travel time, and checking forecasts and road conditions—especially before crossing mountain passes.
