Weekend Smoke Outlook

Smoke models are suggesting improvement across central Idaho and southwest Idaho Saturday.  The Panhandle from Coeur d'Alene and north will continue to receive impacts from Canadian wildfires and will not benefit from the general improvement.  Transport winds look to bring smoke into central Idaho to as far south as Latah County, so expect hazy conditions in the afternoon Saturday there. Eastern and south-central Idaho will continue to see impacts Saturday as a southwesterly wind transports smoke into the area.  Additionally south of a line from Island Park to Boise should expect to see haze aloft Saturday so improvements to the monitors across the southwest are not expected to last through today with values increasing tonight.  Smoke will enter the Lower Snake late this afternoon and spread to the east.

Northwesterly winds Sunday will shift smoke south into central Idaho and will provide southern Idaho an opportunity for clearing for the day.  Sunday evening into Monday, drainage into the Upper Snake from fires burning in central Idaho will bring smoke into eastern Idaho, but clearing is expected across the state from the Panhandle and south on Monday with the Panhandle being the only region likely to remain heavily impacted.
