Forecast Discussion:

PM10 is expected to increase this afternoon in dust prone areas as southwesterly winds begin to build. Morning activity at a few of our monitors added onto our blowing dust potential this afternoon is expected to propel PM10 into the Moderate AQI over the next couple of days, but not to any levels of concern or towards the USG AQI category.
