FORECAST SUMMARY: Friday September 16, 2022, through Monday September 19, 2022

OZONE: 8-hour average Ozone concentrations are expected to be mostly Good with a chance of Moderate along the west lake shore.

PM-2.5:  24-hour average Fine Particulate concentrations are expected to be stay mostly Good to Low Moderate.

FORECAST DISCUSSION:

We should see a very pleasant weekend with warmer days and nights.  Saturday will be the better of the weekend days until mostly clear skies.  Southwest winds will push some ozone over Lake Michigan and could impact some of out monitors.  However, with the lateness of the season, it is difficult to believe it could get any worse than Moderate.

Rain chances increase Sunday and Sunday night with a slight chance Saturday night ahead of an incoming cold front.  Clouds and shower potential should keep things in the Good range for the rest of the weekend.  

The weather, in the wake of the cold front that moves through Monday morning, looks to be cooler and dry for the latter half of Monday through Tuesday morning with Good Air Quality.

EXTENDED FORECAST:

Air Quality should be mostly Good to begin the next work week.
