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: USG ozone conditions are possible around Baltimore City on Friday. Dirty air comprised of some residual pollution from Thursday and slightly dirty air from the south will cause ozone concentrations to increase towards the Moderate/USG threshold near and just east of Baltimore city. Other areas will remain within the Moderate AQI range for ozone and/or particles, which will also be elevated due to the presence of residual smoke transported from western US/Canada wildfires. Official forecast for Friday therefore will remain Moderate AQI. Increased cloud cover on and late-day rain will mitigate ongoing ozone issues but Moderate AQI for ozone may still persist east of the mountains. Unsettled weather persists into Sunday, allowing cleaner conditions to prevail with Good air quality excepted. –MDE
