Hazy conditions today

Hazy conditions are present over southern Idaho and these conditions are expected to remain in place as regional smoke increases in density and coverage to encompass all of Idaho. At the surface, smoke looks to remain over southern Idaho and expand north throughout the day into the Central Idaho Mountains.  

Tomorrow looks to bring smoke currently over Oregon and Washington into western Idaho tomorrow morning and expanding through Central Idaho to the Montana border by 6pm tomorrow evening.  Smoke aloft is anticipated to increase throughout the day tomorrow across all of Idaho, excluding the extreme northern Panhandle. This smoke is anticipated to mix down to the surface with a more neutral flow regime establishing tonight and tomorrow.
