Forecast Discussion: Some light winds expected overnight into Tuesday morning will help to increase particle concentrations along with the aid of the transport of a humid, modified air mass. Increasing winds during the day along with moderate precipitation in the afternoon during the passage of a cold front will limit the daily average to the upper-good range. Extended Forecast: Steady winds on Wednesday along with the transport of a cooler, drier air mass will decrease particle concentrations further into the good range. Breezy conditions will continue into Thursday but will begin to diminish later in the day allowing for a slight increase in particle concentrations. A clean northerly transport will continue to provide the region with good air quality. -Wiles
