A strong ridge of high pressure will build over the Northern Rockies this weekend into the first part of next week, bringing a significant return of heat. Temperatures will steadily climb each day, with afternoon readings back in the 90s for most valleys of western Montana. The lower valleys of north central Idaho could even break the century mark. These temperatures are expected to be around 10 to 15 degrees above seasonal averages. We'll be monitoring the Orofino to Riggins region for potential heat risk conditions by early next week. It's also worth noting that lingering smoke from regional fires could potentially degrade air quality and keep temperatures from reaching their full potential.
