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)

Forecast Discussion: Wednesday, October 16, 2019: Cyclonic flow around low pressure centered over the Great Lakes is helping to keep cloud cover over the state. High pressure ridging is gradually building into the state and clouds will break up later this afternoon and evening. Air quality is deep within the Green/Good category across the state. The ridge quickly shift east late tonight/ tomorrow and a southerly return flow will bring warmer air into Minnesota on Thursday. It will be mostly sunny with highs in the 50s to low 60s. The sun will push ozone a bit higher but lessening daylight will keep concentrations Green. Particulate will likely build a bit tonight but will still hold at Green. The warm air transport increases further on Friday ahead of a weak low pressure system. High temperatures will approach or exceed 70F in southern and central Minnesota under partial cloud cover and a gusty southerly breeze. AQIs will hold steady in the middle Green or Good category. Mild and tranquil weather will be on tap for the weekend before next low pressure system tracks across our area early next week. Air quality is expected to be Green in most parts of the state over the weekend.
