Meteorology/Dispersion Discussion

Last Updated: 2026-10-28 14:41:56.552782 MST

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

Low pressure consolidates over the PacNW on Thursday  causing a more stable airmass to setup over MT and ID. Most areas POOR dispersion though higher elevations in eastern ID could be above inversion on the ridges for POOR to FAIR dispersion. 

Friday southwest flow aloft and warmer temperatures begin to influence more of central and southern ID and southwest MT. FAIR dispersion in eastern parts of central ID, most of southern ID and southwest MT. POOR dispersion all other areas as clouds increase which limits surface heating. Winds light most areas. 

Saturday warm air aloft moving through most of the region bringing clouds and precipitation to much of ID. ID Light winds with limited surface mixing for POOR dispersion. In MT many areas will see stronger inversions which will support POOR dispersion.
