Expect the AQI to be predominantly in the Moderate level with elevated Fine particles (PM2.5). A quick moving cold front cleared out the Valley of pollutants for today. However, High pressure quickly building back over S NV will result in weather favoring the return of elevated levels of PM2.5 in the Vegas Valley. AQI is EPA's Air Quality Index - information is on EPA AirNow and the DAQ web pages.
