PM10 and PM2.5 were in the Good AQI range yesterday. Overall the rainfall in recent days will help limit increases in PM10 and PM2.5 through the weekend. Early next week, forecasts hint at more afternoon showers and storms, so hourly PM levels have been adjusted to show that potential. While there will be hourly increases in PM10 and PM2.5 early next week, daily average PM levels are forecast to be in the Good AQI range through early next week.
