Meteorology/Dispersion Discussion

Last Updated: 2026-11-09 17:22:29.463894 MST

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

High pressure dominates Wednesday and Thursday for POOR dispersion everywhere with strong inversions and light winds. 

Friday a warm front moves through ID and western MT bringing warmer temperatures and increased winds aloft. This causes better mixing most areas with FAIR to GOOD dispersion. Inversions may not break as easily over central and eastern MT and southeast ID for POOR to FAIR dispersion. Cold front overnight will keep inversions from forming until very late which keeps dispersion favorable. 

Saturday higher pressure develops over ID and western MT with high level cloud cover to create POOR dispersion. Still breezy over central and eastern MT for POOR to FAIR dispersion.
