FORECAST SUMMARY: Friday July 8th, 2022, through Sunday July 10th, 2022

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

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

FORECAST DISCUSSION:

There is a chance of rain showers this afternoon and evening for southern Michigan with areas in northern Michigan remaining dry. Once the rain exits the area, a High-pressure system positions itself over the western Upper Peninsula on Saturday until it slides to the south over the Saginaw Bay region Sunday morning. This will result in relatively clear skies and light winds for the majority of the weekend. With the High-pressure in place, surface winds will predominately be from the northeast with surface temperatures ranging from the upper-70s to low-80s F. Upper-level winds appear to be from the northeast as well with upper-level temperatures in the low-teens C.

In terms of air quality, as stated earlier in the week, regional PM-2.5 concentrations hang around, but concentrations should not reach anything higher than the low-Moderate range. Light winds in the morning hours will cause a buildup in concentrations but those will slowly dissipate as each day carries on. Ozone is not predicted to be an issue this weekend with the help of northeast winds and cooler upper-level temperatures. Ozone development looks to be a potential issue come Monday as a warm front comes through, shifting winds to the southwest. That is why this forecast is made out to Sunday, with an updated forecast for Monday coming Sunday morning.

EXTENDED FORECAST:

As stated above, a slight warmup is predicted for Monday with winds shifting to the southwest, so the forecast will be updated Sunday morning.
