FORECAST SUMMARY: Monday, August 7th, 2023, through Friday, August 11th, 2023

PM-2.5: PM-2.5 concentrations are expected to be in the Good to Moderate range.

OZONE: Ozone concentrations are expected to be in the Good to Moderate range.

FORECAST DISCUSSION:

The majority of Michigan wakes up to overcast skies and damp grass from overnight showers. The sun will begin to peak out later in the day and into tomorrow as the system that brought the rain leaves the region. A high-pressure system sets up to our northwest tomorrow which will provide sunny skies and surface temperatures in the low-80s. This weather pattern remains the same until Wednesday night into Thursday when a low-pressure system traverses the area, shifting us back into possible rainy conditions. Possible multiple rounds of on and off rain will be present until Friday and into Saturday.

In terms of air quality, wildfire smoke looks to remain out of the region for this week, so PM-2.5 concentrations will remain in the Good to Moderate range. For Ozone, multiple changes in airmass will keep the air clean of stagnation and a buildup of Ozone concentrations. The one day we will keep an eye on is Wednesday, which will have surface temperatures in the low-to-mid 80s and predominantly southwest winds. This may allow for Ozone to develop in the southwest Michigan area but is not expected to be widespread. The approaching system may increase clouds Wednesday afternoon, so this may help hinder Ozone development. We are rather confident that Ozone will not be a widespread issue on Wednesday and the rest of the week, so this forecast will be updated on Friday for the weekend ahead.

EXTENDED FORECAST:

Cooler summer temperatures remain in place for the weekend with a chance of rain as of right now. Overall air quality will remain Good.
