Monday short lived high pressure causes winds to decrease with moist westerly flow bringing cloud cover. Most areas will see limited surface mixing for POOR to FAIR dispersion. Mid to higher elevations in southwest MT and east central ID will see better mixing due to stronger winds aloft but valley floors will stay sheltered.
A disturbance moves through ID tonight and on Tuesday this disturbance moves through western and central MT. Expect stabilizing airmass over ID during the afternoon with decreasing winds though a few areas might still be breezy in the morning. Generally expect POOR dipsersion over ID. Over MT stronger winds with FAIR to GOOD dispersion except far northwest MT AS1 and AS2 where winds will quickly become weak during the afternoon for POOR to FAIR dispersion.
High pressure dominates Wednesday and Thursday for POOR dispersion everywhere with strong inversions and light winds.
