Meteorology/Dispersion Discussion

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

Friday southerly flow aloft increases over ID and western MT with strong low pressure moving into OR. This brings moisture and high clouds to ID and western MT with increasing southeasterly winds over central and southern ID and southwest MT. POOR to FAIR dispersion north ID and western MT where inversions will be harder to break due to cloud cover and light winds. FAIR to GOOD dispersion central and southern ID and southwest MT with stronger winds.  This is a noticeably good pattern for cleaning out western ID airsheds like AS14 and AS15. 

Saturday a cold front moves through ID into western MT with clouds and scattered precipitation. Winds decrease over most of ID but are maintained in the Snake River drainage. POOR to FAIR dispersion ID and western MT except southwest MT FAIR to GOOD. FAIR dispersion southwest MT with breezy winds but POOR dispersion central and eastern MT.  

Late Saturday into Sunday and reorganization of low pressure over the PacNW drives a stronger southwest flow into the western NRGA with higher moisture content. Pattern will feature better chances for showers in the valleys and snow in the mountains but snow levels should stay off most valley floors. Generally POOR dispersion due to low mixing heights on Sunday.
