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: Today, moderate southwesterly to westerly winds will disperse pollutants and transport a clean air mass into Rochester, leading to Good AQI levels. Tomorrow, moderate east-northeasterly winds will develop ahead of an approaching low pressure system, effectively dispersing pollutants. As a result, AQI levels will be Good. Friday, the low pressure system will pass through Rochester, enhancing atmospheric mixing and yielding Good AQI levels. Saturday, northwesterly winds behind the departing low pressure system will transport a cleaner air mass into the Rochester region, keeping AQI levels Good. Sunday, winds will weaken in Rochester, allowing pollutants to accumulate. However, low regional pollutant carryover from Saturday will keep AQI levels Good. Monday, moderate southerly winds will gradually bring pollutants and moisture into Rochester, enhancing particle production. However, these winds will be strong enough to disperse pollutants, resulting in Good AQI levels.
