Forecast Discussion: Good air quality on Sunday will remain as a result of easterly winds bringing clean ocean air over the region. On Monday, a high pressure system will cause light winds shifting from easterly to southerly. Air quality in the upper Good range is expected. Clear skies, southwesterly winds, and ample moisture on Tuesday will allow ozone and fine particle pollution to increase into the low Moderate range for most locations ahead of an approaching cold front that arrives by the evening. - MDE
