Forecast Discussion: Periods of rain and clouds will move through the region on Saturday and Sunday, leading to Good air quality both days. On Monday, light winds and some recirculation of the local air mass will lead to increasing pollution levels. At this time, developing rain and storms should help to keep ozone in check, leading to Moderate ozone AQI conditions east of the mountains. -MDE
