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.

Forecast Discussion: Updated Wednesday, May 27, 2020 ** OZONE HEALTH WATCH THURSDAY MAY 28, 2020 ** The afternoon high temperatures will continue their climb as high pressure builds into the area. The afternoon highs will be in the triple digits and give a good run at 110 degrees later in the week. The ozone level reached the health standard at Queen Valley yesterday and are expected to be slightly lower today due to afternoon/early evening breeziness. However the winds are forecast to be a bit weaker on Thursday and so expect a slight uptick in ozone levels and so have an ozone health watch issued. Additionally, Friday’s forecasted weather conditions are more favorable for ozone formation and transport and so an ozone High Pollution Advisory (HPA) may be issued. Anyone with respiratory and/or heart ailments should limit outdoor activities during the afternoon and early evening hours when ozone levels are at their highest. This probably won’t be too difficult to do considering how hot it will be outside. The PM10 levels everywhere except for Hidden Valley are forecast to be in the good to low moderate range. As is typically the case this time of year, Hidden Valley’s early morning wind conditions coupled with locally generated dust will play a large part in the daily PM10 levels. The PM10 volatility at the Hidden Valley monitor is in full force this morning as hourly PM10 averages have fluctuated from 33 ug/m3 all the way up to 404 ug/m3! The short-term PM10 concentrations (5-minute averages) are even more active going from the single digits to over 1,528 ug/m3 all within the same hour. Today’s daily PM10 average at Hidden Valley is expected to remain under the health standard (unlike yesterday which exceeded). Looking out a little farther, the forecasted PM10 level at Hidden Valley is over the health standard on Friday and similarly high PM10 levels forecasted at Hidden Valley for this upcoming weekend. Stay tuned. The high pressure currently in control will be nudged eastward this weekend by an upper level low pressure system in the southern Pacific ocean as it moves towards the area and eventually northward up and over the ridge of high pressure with another upper low expected behind it early next week. Neither one of these systems will bring any direct precipitation to the area. However the movement of the ridge of high pressure eastward will put it in a Monsoon type of setup and will help usher in some atmospheric moisture from the south and east. Dry lightning and perhaps a thunderstorm or two in eastern areas of the State this weekend pose a potential wildfire hazard (and associated smoke) and so we’ll have to keep an eye on that developing situation. Check back tomorrow for an updated air quality forecast. Forecaster: S. DiBiase
