FORECAST DISCUSSION
A low-pressure cell moves across the upper Great Lakes, during Friday, dragging a series of fronts with it. Friday snow will likely impact areas from upper and central Lower Peninsula and west to Lake Michigan.
As the weekend progresses, West Michigan snow may get heavy later Saturday afternoon into Saturday night and then again Sunday evening through Monday morning as an Arctic front arrives. This front will usher in some bitterly cold Arctic air which could lead to some periods of significant lake effect snow. The Arctic air arriving Monday morning will produce falling temperatures during the day and lasting through Tuesday. These bitterly cold temperatures will be further aggravated with strong winds and wind chills.
In terms of Air Quality, Good Air Quality should persist through the forecast period.
EXTENDED FORECAST:
Air Quality is expected to remain mostly Good entering the upcoming work week.
