The highest AQ index in Indiana (as of 18:00 EDT) is currently the Muncie area. Particle Pollution (PM2.5) is measuring at 64 (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: PM2.5 was good on Monday and a mix of good and moderate on Tuesday. Ozone was good across the state Monday with moderate conditions for SE on Tuesday and good for SW. Temperatures for Southern Indiana are forecast to be in the upper 90's to low 100's for Wednesday through Friday with overnight lows in the mid-70's. Wednesday winds are forecast to be from the SW 0-10 MPH, Thursday winds are forecast to be from the West 0-10 MPH, and light and variable winds Friday. Chances of rain are possible later Thursday into Friday, but looking to stay sunny and dry besides that. A heat advisory is in place for the entire region for Wednesday through the weekend for heat index values between 100 to 109 degrees. The NOAA 06Z BC model for PM2.5 forecasts moderate levels for Wednesday through Friday. The Canadian model shows good levels for that entire forecast period. I am going to air on the cautious side and go moderate PM2.5 for the entire forecast period due to sunshine, high dewpoints, and temperatures nearing 100 degrees. The NOAA 06Z BC model for ozone predicts good levels for Wednesday through Thursday with moderate levels Friday for SW and moderate levels for the entire period for SE. The Canadian model forecasts moderate levels with highest levels of ozone for SE. A mix of good and moderate seems likely with sunshine initially with warm southerly flow, but then a passing frontal system clearing us out. Mixing heights are forecast to be around 6,600 ft. Wednesday, 7,000 ft. Thursday, and 5,500 ft. Friday.
