Meteorology/Dispersion Discussion

Last Updated: 2026-10-07 20:53:23.913463 MST

Airshed charts and summary table can be found here and maps can be found here.

On Thursday, high pressure keeps winds light and dispersion POOR to FAIR in north and west ID and north MT. The area of FAIR to GOOD dispersion expands in south and east ID and south MT as the high starts to weaken.

Friday marks a significant change in dispersion around the area, with no areas of POOR or even FAIR dispersion shown. Northwest ID improves to GOOD to VERY GOOD dispersion, and the rest of ID and MT has VERY GOOD to EXCELLENT dispersion.

Much colder temperatures on Saturday bring dispersion in north ID and west MT down to POOR to FAIR conditions behind a strong cold front. Ahead of the cold front, south ID maintains GOOD to VERY GOOD conditions, while breezy winds in central and east MT keep dispersion there FAIR to GOOD.
