Tuesday, September 3rd, 2019 through Monday, September 9th, 2019
Ozone: 8-Hour average Ozone concentrations will be mostly Good to Low Moderate through the forecast period.
PM-2.5: 24-hour average Fine Particulate concentrations will be mostly Good.
Tuesday through early Wednesday will be a bit unsettled as an active weather system moves through the Midwest. Air Quality should remain Good with ample clouds and high probability of precipitation.
High pressure follows later Wednesday and will dominate the remainder of Wednesday and into early Thursday. Northerly wind flow will provide sunny skies, cooler temperatures and Good Air Quality.
Temperatures should warm a bit late Thursday into Thursday night in advance of a small system which is expected to pass Friday morning. Light winds and stagnating air could produce some Low Moderates during Thursday afternoon and Friday in southeast Michigan but I expect mostly Good elsewhere.
High pressure returns for the weekend with mostly northerly air flow and Good Air Quality. Shifting winds to the east-northeast are likely during Monday with little chance of Air Quality issues.
Air Quality should be mostly Good going into the next work week.
