PM-2.5: 24-hour Fine Particulate concentrations will be generally Good to Low Moderate through the forecast period.
The forecast period should be fairly quiet starting with a period of warming up and drying out. A surface ridge of high pressure will drift eastward during the first portion of the week putting the region under southwesterly winds. While the warmer temperatures, sunshine, and a chance to dry out will be welcomed, the chance for fine particulates to creep into the Low Moderate range will be good.
A small clipper system will sweep through the region, late Wednesday, which should clean out any Moderates that may have accumulated. Clean conditions and Good Air Quality should persist until later in the weekend when warmer southwest winds return.
Air Quality is expected to remain mostly Good going into the next work week.
