Forecast Discussion: Ozone was good yesterday and PM2.5 is moderate central and mixed south.   Fog will burn off and become mostly sunny, hot and hazy for today through Wednesday in southern regions  of the state.   A disturbance should give rise to isolated convection in central and northern parts of Indiana.  High pressure at the surface and a broad ridge aloft will maintain an inversion cap and subsidence.  Winds will be light and pollutant levels could be high for much of this week.
