Forecast Discussion: Ozone was mostly good with isolated moderates and PM2.5 has declined to the upper 20’s after some higher readings due to fireworks. Seasonably warm and very humid with a chance of thunderstorms each day. A cold front will slowly cut through the Great Lakes over the next 36 hours. Central Indiana will have a break from the heat and humidity on Wednesday. At that time, the front will lie across southern Indiana. A wave will lift the front northward again on Thursday continuing the threat of showers.
