Warm surface temperatures and an unstable atmosphere allow today’s dispersion to be mostly VERY GOOD to EXCELLENT across the area.

From the 17^th to the 19^th, dispersion decreases somewhat due to cooler surface temperatures, but unsettled weather keeps dispersion GOOD in most airsheds. A few airsheds in central and southern Idaho drop to FAIR conditions under higher pressure aloft.

On the 20^th, as higher pressure briefly affects more of the forecast area, dispersion drops to FAIR in most airsheds with an area of POOR dispersion in western Idaho.

A weather system moving past us to the north will bring dispersion back up to EXCELLENT in several airsheds for the 21^st, but western Idaho returns to POOR dispersion for the 22^nd.
