Over the weekend ozone was in the Upper Good AQI range. With the additional rainfall coming today and tomorrow, ozone levels will fall. Drier conditions will come on Wednesday, and this will increase daily ozone levels to the Upper Good AQI range.
PM10 and PM2.5 were typical in the Good AQI range through the weekend with the largest increase Saturday evening and into the early morning hours of Sunday. There have been brief increases in PM levels this morning from local activity. Overall, today and tomorrow could see brief increases in PM10 due to stronger winds associated with the incoming rain. There will be a higher chance to see these increases today versus tomorrow due to the currently dry soils. Wednesday drier conditions return, but strong winds are not expected to come until possibly Thursday night/Friday morning. PM10 daily levels are forecast to remain in the Good AQI range, and PM2.5 will have similar trends.
