The smoke came in Friday evening and Saturday morning and it has stuck around. Air quality across the state ranges from moderate in the southeastern corner to hazardous in the north. It is forecast to be in the moderate to very unhealthy range today.
A thick shield of smoke continues to cover most of the Northwest today as southwest to west winds push smoke from Oregon and California fires into Idaho. There are also several fires burning in Idaho that are contributing significant smoke to the mix as well. North Idaho may see some short relief this afternoon but it is unlikely to last as smoke continues to stream in from the west.
Southeast and east Idaho will see some improvement this afternoon with southwest flow bringing in relatively clear air from Nevada and Utah.
Overall, unfortunately, there is unlikely to be significant relief until later this week. Conditions are expected to remain about the same through the week as they have been for the past two days with significant clearing not expect until at least Friday when the large low-pressure system off the coast looks to move through.
