Expect smoke just about everywhere but the Southeast

Smoke impacts today are expected to be greatest over the Panhandle, Central Idaho, Southwest Idaho, and the East Salmon Mountains. This afternoon, the Salmon river corridor to Riggins looks to keep smoke with impacts south to McCall. Central Idaho and Southwest Idaho should expect to see hazy conditions. Due to light transport winds, smoke may lift but will likely again settle into the area with the setting sun. This evening, expect smoke to drain into the drainages of the Upper Middle Fork Salmon, Lower Middle Fork Salmon, Middle Salmon, Upper Salmon, Pahsimeroi, and Lemhi. 

Tomorrow, the passing cold font and increased wind speeds will get rid of smoke in the afternoon; however, ample smoke is expected to come into north Idaho in the evening as fire activity increases. The highest concentrations are expected to be located over the Clearwater, Spokane-Coeur d’Alene Corridor and north within the Purcell Trench, and southwest Idaho. Salmon and the northern drainages should expect to be impacted from regional fires in the afternoon beginning around 2pm. On Saturday night, the Purcell Trench looks to be the most heavily impacted with drainage smoke that is not expected to lift before 5pm on Sunday. Once more, Salmon and Southwestern Idaho will see impacts from fires burning to the southwest. Expect similar conditions on Monday with higher readings in the morning and lifting in the afternoon. Expect impacts across all of northern Idaho, central Idaho, and southwest Idaho.

This shows forecast daily maximum smoke concentrations on Friday with maximum values over the Panhandle and Central Idaho with hazy conditions over Central Idaho and within the Snake River Plain.
