Light wind and sunshine helped make Thursday very comfortable across most of southwest and central Idaho with Boise hitting the upper 60s and McCall, the mid 50s.
As southwest flow amplifies ahead of an approaching low pressure system, temperatures warm up a few degrees into the lower 70s in the Treasure Valley on Friday making for a very pleasant day to get outside and take in the changing colors. Clouds overspread the area Friday night ahead of the incoming storm system. Scattered showers develop after midnight in eastern Oregon and southwest Idaho before sunrise.
Temperatures cool another 10° into Saturday with plenty of cloud cover and on-and-off showers throughout the day. Snow levels will be between 7000 and 8000 ft. with light accumulation expected for higher peaks. Scattered rain showers continue into Sunday with very cool temperatures. Highs will struggle to reach 60° in the valleys and 50° in higher elevations.
Cool and unsettled weather lingers into Monday, followed by gradual warming thereafter. Temperatures return closer to normal with highs in the upper 60s and lower 70s. A pleasant stretch of Fall weather is likely after this weekend's cool down.
