FORECAST SUMMARY: Friday August 19th, 2022, through Monday August 22nd, 2022
OZONE: Ozone concentrations are expected to be in the Good to low-Moderate range.
PM-2.5: PM-2.5 concentrations are expected to be in the Good to low-Moderate range.
FORECAST DISCUSSION:
The pleasant weather conditions Michigan has had all week will carry into the weekend with a chance of spotty rain showers for areas across the state. Saturday looks to have surface temperatures ranging from the mid-70s to mid-80s the more south you go. Winds will be dependent upon the impending Low-pressure and associated cold front that will drift across the state early Sunday. On Saturday, winds will predominantly be southerly but become more mixed as the Low-pressure approaches and they eventually become more northerly as we get into Sunday afternoon. As stated above, the rain will be spotty across Michigan, with the majority of the rain occurring overnight into Sunday morning. There will be some left-over rain on Monday, but we eventually dry out as Monday carries on.
In terms of air quality, more of the same when it comes to PM-2.5 concentrations. Light early-morning winds will cause a buildup in concentrations that will slowly dissipate as mid-day winds pick up. For Ozone, aside from the rain hindering development, unfavorable winds for Ozone development will be present for the majority of the weekend. There will be some hours on both Saturday and Sunday where winds shift to more SW flow, which is favorable for Ozone, but it will not be long enough to build up concentrations here in Michigan. As stated above, the spotty rain showers will help keep concentrations at bay for both Ozone and PM-2.5 and will also help to clean out any build up.
EXTENDED FORECAST:
Air quality looks to remain in the Good range as we start the next work week.
