Discussion:
A trough of low pressure will be over or just west of northern CA through Tuesday. Mixing heights and transport winds will be above Saturday's levels, so smoke dispersion will be more active through Tuesday. Areas near active fires will see air quality and visibility improve during afternoons.

The trough will still be in place from Wed-Fri, but it will be weaker, leading to lower mixing heights and lighter winds. In general, smoke dispersion will diminish during the outlook period, but not to the point of Saturday (yesterday).
