Dispersion Discussion May 8 2026

Decreased cloud cover and warmer temperatures on Friday will support GOOD to VERY GOOD dispersion. Winds a bit on the light side over ID so smoke may not move quickly but mixing should be adequate to support the favorable dipsersion. Stronger winds over MT.

Upper level ridge breakdown Friday night with a new ridge quickly forming on Saturday. Light winds and stronger mid level inversions for POOR to FAIR dispersion over northwest MT and north ID. Elsewhere more unstable for better mixing and GOOD dispersion.
