Boise, Idaho – Patchy smoke and scattered thunderstorms could complicate weekend plans across southwestern Idaho, with storm chances rising through Saturday afternoon and evening. Temperatures will push toward the upper 80s, but unsettled skies may bring brief heavy rain and lightning.
According to the National Weather Service in Boise, showers and thunderstorms are most likely after 3 p.m. Saturday, with a 40% chance of precipitation. Areas of smoke are expected through the weekend, potentially reducing air quality and visibility, particularly in the Treasure Valley.
Drivers along I-84 between Nampa and Boise could see slower travel conditions in smoky or wet patches, while outdoor events may face last-minute disruptions. East winds shifting southwest may carry smoke into neighborhoods Saturday night before easing on Sunday.
Sunday will be mostly sunny with highs near 88, though haze may linger. By Monday night and into Tuesday, shower chances return, though coverage is expected to be scattered. Cooler temperatures in the mid-70s are likely by midweek, offering a break from the heat.
