FORECAST SUMMARY: Monday, February 28th, 2022, through Monday, March 7th, 2022

PM-2.5: PM-2.5 concentrations are expected to be Good throughout Michigan this week.

FORECAST DISCUSSION:

As of Monday morning, a low-pressure system sits over the Minnesota and North Dakota border. This system will track to the east and make its way over Michigan early Tuesday morning. A rather weak system, it will not provide any major precipitation for Michigan but will, however, raise temperatures to the low-40s for southern Michigan and mid-to-upper 30s for northern Michigan. Another system arrives Wednesday afternoon which will provide some precipitation, but again, nothing too major. Once the Wednesday system exits the area, it will drop temps along with it as winds shift to more northerly flow until Friday morning when winds shift to more east-southeast flow.

The ESE wind flow on Friday is due to yet another system approaching the area Saturday. This system will bring windy conditions and rainfall for the southern portions of the state and snowfall for the northern portions of the state. In terms of PM-2.5 concentrations for the week and forecast period, there will be some hourly moderate conditions in the southern portions of Michigan in the morning time throughout the week. As the days carry on, and winds pick up, the 24-hour averages each day should level out to Good concentrations. With the numerous systems coming through the Great Lakes region this week, particulate matter won’t be able to build up as much, with the exception of light winds in the morning time which could cause some build up for a few hours.

EXTENDED FORECAST:

Concentrations and air quality looks to be Good to low-Moderate to start next week.
