High pressure building back in today to reduce dispersion to POOR over MT and ID. Southwest MT and central and eastern MT POOR to FAIR dispersion with weaker inversions but inversions becoming stronger over western MT for POOR dispersion.
Saturday high pressure is dominate for widespread POOR dispersion. Central and eastern MT may have better mixing with warm temperatures and sunshine.
Sunday is an upper level ridge breakdown with winds increasing across MT and parts of ID. All of MT FAIR to GOOD dispersion with scouring of most airsheds. FAIR to GOOD dispersion in the exposed valleys of northern and central ID but north to west valleys likely still POOR to FAIR dispersion. Southern ID not as much wind push into the area and dispersion remains POOR.
Monday short lived high pressure returns stable air but another disturbance on Tuesday may help improve dispersion.
