Forecast Discussion: Increasing humidity with light winds in the morning, coupled with transport aloft from the west, will allow particle concentrations to increase into the Moderate range on Saturday. Extended Forecast: A cold front will cross the forecast area early Sunday and cool, dry air will arrive immediately in its wake. Air quality will improve to the Good range. Limited vertical mixing on Monday will lead to an increase in particle concentrations but the day will start very clean so that any rise will be limited to the upper end of the Good range. -Ryan
