A deep area of low pressure is in place over Idaho for the first day of Fall, meaning a continuation of cool, rainy, and cloudy weather. Snow levels will be down near 6000 ft for the next few days as well, with snow advisories for the Central Mountains. The weekend looks to be a bit more calm with warmer temperatures, though still quite a bit below average for this time of the year.
Friday: A chance of showers and mostly cloudy, with highs in the upper 40s.

Saturday: A chance of showers in the morning and partly cloudy for the afternoon, with highs in the 50s.
Sunday: Mostly sunny for the Snake River Plain, with a few lingering flurries and light showers for the mountains near Jackson Hole. Highs into the upper 50s.
