Forecast Discussion: FORECAST SUMMARY: Monday, July 25th 2016 through Monday, August 1st, 2016 Ozone: 8-hour Ozone values will be Good to Moderate during the forecast period. PM-2.5: 24-hour Fine Particulate concentrations are expected to be mostly Good to Low Moderate. FORECAST DISCUSSION: After a week of above normal temperatures, high humidity, and a constant threat of elevated ozone, this week will appear to relatively quiet in comparison. This week will show more typical July temperatures with daily highs in the 80’s. High pressure will build in the first half of the week to dry things out. A low pressure system will approach the region during the Wednesday-Thursday time frame bringing the threat of clouds and shower activity. The forecasted wind patterns, over the week, do not show any of the usual patterns we see for elevated ozone. The models are not showing any extended period of southwest winds to transport high levels of pollutants over Lake Michigan. The winds over Southeast Michigan will originate from areas of clean air the majority of the time. As such, I am not seeing any threats of elevated ozone although it is not hard to reach Moderate levels on sunny days with low winds. EXTENDED FORECAST: A fair amount of cloudiness and shower potential will endure through the weekend.
