Near 100-Degree Heat and Storm Chances Return to Southwest Idaho
US · Published Aug 19, 2026
Southwest and central Idaho are set to experience near 100-degree temperatures later this week as high pressure strengthens over the region.
According to Idaho News 6, isolated showers and thunderstorms are possible this afternoon, primarily in higher terrain areas.

Impact & Risks

The combination of high temperatures nearing 100°F (37.8°C) and gusty winds up to 35 mph could increase the risk of heat-related illnesses and fire hazards in southwest and central Idaho. Wildfire smoke from Oregon and Washington may also lead to reduced air quality, particularly in Baker County, Oregon, potentially affecting individuals with respiratory conditions. Lightning from isolated thunderstorms poses a risk of new fire starts, especially in areas with dry vegetation. Residents in lower elevations and higher terrain should remain cautious as the heat intensifies and storm chances increase.
