Fairly good weekend on the way

Impacts from smoke today can be expected to be confined to upper level haze over southwestern Idaho and northeast into central and northern Idaho due to winds from the southwest bring smoke from the fires still burning in California and Oregon. This looks to continue on Saturday with increasing coverage to all of southern Idaho as the winds come from the west. Optimistically, it looks as though the Panhandle and parts of central Idaho will clear out during the afternoon tomorrow. 

Saturday night into Sunday, the Panhandle looks to be impacted by smoke from Washington with clearing in the afternoon. South Idaho should expect to see similar conditions to Saturday. By Monday, north Idaho again looks to clear while south Idaho will still have smoke aloft. All weekend, we look to be more impacted by transport smoke rather than smoke from local fires.

This image shows the modeled smoke aloft over Idaho this afternoon (09/07/18 4pm MDT). It shows a large plume of smoke being transported into southwest and central Idaho from Oregon and California.
