Forecast Discussion: Ozone was good for central Indiana but upper 70’s ppb in Louisville, KY and a 75 ppb down and across the river from Evansville. PM2.5 continues to increase within the moderate range. The surface high is moving off to the east but the upper level ridge still covers the eastern half of the country. An upper level disturbance sinks south into the lower peninsula of Michigan, then will retreat northward. Weather continues to be hazy, hot and humid as temperatures push farther into the 90’s. When little changes, persistence seems to be the best forecast.
