Ozone: 8-Hour average Ozone concentrations will be mostly Good through the forecast period.
PM-2.5: 24-hour average Fine Particulate concentrations will also be mostly Good.
The last day of September began as a damp, foggy morning. But by the time the first day of October arrives, a warm front will have passed through the state and temperatures will push into the low 80’s. While warm enough to potentially sustain some ozone development, shorter days and mostly cloudy skies will be enough to keep Air Quality in the Good category.
The cold front associated with this system will pass through Tuesday night and linger in the area through Thursday. The entire system will be through the region Thursday and will set up the Midwest for below average temperatures through the weekend. Although cooler than normal, sunny days should make for a nice weekend and Good Air Quality.
Air Quality should be mostly Good going into the next work week.
