Forecast Summary:

Tuesday February 22nd, 2022, through Monday February 28th, 2022

PM-2.5: 24-hour average Fine Particulate concentrations are expected to be Moderate during Tuesday, then transitioning to Good for the remainder of the forecast period with the exception of some Low Moderate during the early portion of the weekend.

FORECAST DISCUSSION:

As of Tuesday morning, a low-pressure system, located over northern Missouri, will track northeast during the day.  Warming temperatures and ample moisture, ahead of the passage of the low, could trigger some Moderate conditions during Tuesday.  We expect that low pressure to pass through Michigan by midnight, Tuesday night into Wednesday morning. 

 Following the passage of the low-pressure system, winds will switch to the northwest and provide colder, drier, and cleaner air under a high-pressure cell.  We may see some snow, Thursday night, as a frontal system passes to the south of Michigan, but Air Quality should remain good.

 The best chance of any other moderate Air Quality looks to arrive during Saturday when winds brief return to a southwest direction.  Those winds will be short-lived, and we should be back into a clean northwest wind by Sunday.

 We anticipate good Air Quality will then persist for the remainder of the forecast period

EXTENDED FORECAST:

Air Quality is expected to be remain mostly Good to Low Moderate to start the next work week.
