Forecast Discussion: Ozone readings in the forecast area were good and PM2.5 readings are moderate. An upper level ridge centered over the Rockies is building eastward into the mid-Mississippi Valley yet still to our west. The trough will move further to the south so skies will be sunnier going forward. Temperatures will reach into the low to mid-90’s tomorrow with dew points in the 60’s. Trajectories show a modest amount of subsidence but show some ventilation particularly central and north.
