Forecast Discussion: Ozone was mostly good yesterday with a few very low moderates. PM2.5 is all moderate. A large ridge is over the Rockies with a trough across the northern lakes. A cold front should cut through central Indiana Wednesday morning and move into Kentucky by early afternoon. Winds will be from the north for Wednesday and Thursday but become light with a surface high pressure settling into the southern Great Lakes. Temperatures will remain below normal for the week.
