Areas of western Idaho will continue to experience POOR dispersion under cooler surface conditions with clouds and precipitation on the 13th, with a chance for some thunderstorms around the mountains; the rest of Idaho and Montana can expect FAIR to EXCELLENT dispersion, as surface temperatures will gradually warm and upper level high pressure is expected to stay just to our south.

The 14th and 15th, with warm and dry surface conditions and high pressure continuing to stay to our south, are forecast to have FAIR to EXCELLENT dispersion in almost all airsheds ahead of the next significant low pressure system that moves in with rain, snow, and cooler temperatures on the 16thIncreased winds are also forecasted for the 14th in southern Idaho and for the 15th in much of Idaho and Montana.

Between the 16th and the 18th, with decreasing temperatures around the area and widespread rain and snow, dispersion gradually drops from generally VERY GOOD to EXCELLENT to generally GOOD by the 18th.

By the 19th, with cooler and more stable conditions, dispersion drops to FAIR in many Montana and central Idaho airsheds and remains GOOD to VERY GOOD in the rest of the Idaho airsheds.
