The highest AQ index in Indiana (as of 16:00 CDT) is currently the Evansville area. Particle Pollution (PM2.5) is measuring at 67 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Particle Pollution (PM2.5) will be in the Evansville area. It is forecasted to be Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Southern Regions: Ozone was good on Monday and PM2.5 was a mix of good and moderate. As of Tuesday morning, PM2.5 is moderate and ozone is good. Surface temperatures are forecast to be in the low 90's Tuesday with mostly sunny conditions. Winds are forecast to be from the SW early becoming light from the NW later in the day, with occasional gusts up to 20 MPH. Dewpoints are into the 60's. Wednesday is forecast to be sunny with a high temperature in the mid to upper 80's with light northerly winds. The NOAA 06Z BC model for PM2.5 forecasts moderate Tuesday and Wednesday for the SE and good for the SE. The Canadian model shows and mix of good and moderate levels too concurring with the NOAA. I think moderate is possible prior to the frontal system later in the day and due to morning observations. Wednesday, good seems more likely, but going to air on the side of caution and go with moderate for SW and good for SE. The NOAA 06Z BC model for ozone predicts good for Tuesday and Wednesday. The Canadian model forecasts good levels too. The cleanout with the cold front, high dewpoints Wednesday, and wind direction makes good likely. Mixing heights are forecast to be around 4,600 ft. Tuesday and 6,000 ft. Wednesday.
