05/28/2019 Forecast Update


Tuesday, May 28th, 2019 through Monday, June 3rd, 2019

Ozone: 8-Hour average Ozone concentrations will be mostly Good through the forecast period.

PM-2.5: 24-hour average Fine Particulate concentrations will be mostly Good with some Low Moderate through the forecast period.


Cooler, cloudy weather will persist through much of the work week as a stationary front lingers in the northernIllinois/Indiana area. This combination of fronts and associated low pressure cells will likely cause outbreaks of nasty weather to our south but Michigan should only experience clouds and showers. Air Quality should remain mostly in the Good range.

We finally begin to dry out on Friday as high pressure begins pushing in from the northwest. Calm winds on Friday may allow some creep in Fine Particulates but Ozone does not appear to be an issue, at this time.

During Saturday, southwest air flow should change over to west/northwest winds later in the day as clockwise winds around the center of high pressure define our weekend wind pattern. These winds should be clean and provide Good Air Quality. Sunday and Monday’s winds should be light but predominantly northerly keeping our weather pleasant and our Air Quality Good.


Air Quality is expected to remain mostlyGood going into the next work week.
