Forecast Discussion: PM2.5 yesterday averaged moderate over almost all of Indiana and good everywhere in Kentucky. Only two sites in Indianapolis were borderline moderate while the rest of the region was good. High pressure will keep the weather dry into late in the week, despite a cold front passing through Tuesday. A ridge will briefly be over the Ohio Valley Wednesday while a strong trough approaches from the Rockies. Humidity returns and thunderstorms are possible Thursday.
