AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Update: If you were curious about the unusually hazy skies this morning, airborne dust has been transported all the way from southern New Mexico and western Texas! Strong and gusty winds began in the southern Great Plains on Monday along a cold front diving southward. Using HYSPLIT air parcel back trajectories, the influx of dust can be traced back from the desert regions of our neighboring states east of Arizona. A western progression of spikes in dust concentrations (i.e., PM10) could be followed across southern Arizona overnight, reaching Phoenix around 6 AM this morning. Breezy winds have since spread to us today and will gradually help push transported dust out of the local area, however, haze aloft will be slow to clear out.

Hope everyone had an enjoyable Veterans Day weekend. We start the short workweek with breezy winds out of the east. Those winds should start to become more apparent as the morning wears on. Gusts to 30 mph are being observed south of the metropolitan over in Pinal County. A northward progression of winds is expected. By evening they shut down and really that is about it for the significant weather of the week.

High pressure slides overhead and becomes the main dictator for our air quality. Mild temperatures, occasional clouds, and light winds are the tangibles out of the upcoming weather pattern. It is the winds, or lack thereof, that brings about some air quality concerns. Hazy skylines are likely in the coming days. Day-to-day recirculation of dust and soot (PM10 and PM2.5, respectively) leads to an increasing trend for our peak daily AQIs. Trends need to be monitored closely throughout the week as stagnation grips the Valley of the Sun.
