Boise, Idaho – Idaho residents are bracing for more hot, smoky conditions that could impact travel and outdoor events as fall nears. Temperatures in Boise are pushing into the mid-90s, and smoke is hanging low across the Treasure Valley, raising air quality concerns. Drivers along Interstate 84 should expect reduced visibility at times, particularly during the evening hours. Outdoor activities, including Friday night football, could be hindered by the heavy haze.
According to the National Weather Service in Boise, highs will reach 96°F Thursday before easing slightly Friday with patchy smoke lingering. Winds from the northwest may help thin conditions, but smoke pockets remain possible through Friday night. By Saturday, a slight chance of afternoon showers could bring temporary relief, though heat remains with highs near 88°F.
Communities from Meridian to Nampa are advised to limit strenuous outdoor activity, especially sensitive groups. Health officials recommend keeping windows closed and using air filters where possible. Travelers are urged to use headlights on smoky stretches of I-84 and allow extra time for evening commutes.
Looking ahead, isolated storms may roll into the Boise area Sunday night into Monday, increasing the risk of sudden downpours and slick roadways. Temperatures will begin to moderate into the low 80s by early next week, signaling a gradual transition toward fall weather patterns.
Smoke and heat remain the biggest concerns through the weekend, but storm chances grow by Monday. The National Weather Service will issue additional advisories if conditions worsen.
