Tuesday a stronger disturbance tracking further north across Canada increases the westerly flow and brings stronger winds to most of the region. FAIR to GOOD dispersion with less wind over west central ID (AS14 and AS15) for POOR to FAIR dispersion.
Wednesday a cold front moves through bringing another round of wind. Montana will see GOOD to VERY GOOD dispersion. Front exits north ID early enough that winds may decrease early in the day and cloud cover will bring weaker surface mixing. POOR to FAIR dispersion in northern and central ID but FAIR to GOOD dispersion in southern ID where winds will stay stronger.
Thursday high pressure builds over the western Great Basin which stabilizes the airmass over north ID and western MT for POOR to FAIR dispersion. Not as stable east of the Continental Divide and better chance to break inversions over southern ID for FAIR to GOOD dispersion.
