FORECAST SUMMARY:

Monday, June 1st, 2020 through Friday, June 5th, 2020

OZONE: 8-Hour average Ozone concentrations will be Moderate to High Moderate on Tuesday, then mostly Good to Low Moderate for the middle and end of week.

PM-2.5:  24-hour average Fine Particulate concentrations will be mostly Good to Low Moderates.

FORECAST DISCUSSION

The best chance for any higher-than-normal ozone numbers will come on Tuesday as we get into a sector of warm, moist air in advance of a Tuesday night front.  The computer models are showing some elevated ozone numbers between Benton Harbor and Muskegon.  I do not think it will elevate into any widespread USG as we are starting with a clean air mass, on Monday, and a front will pass later Tuesday night.  That said, I do anticipate that we will see ample Moderates along the lake shore.  While it is possible that an isolated USG could occur, it does not yet rise to the level of issuing any air advisories.

The rest of the work week should stay in Good/Low Moderate range thus I am not anticipating a need for a daily forecast update unless conditions change.  However, since we are getting into that time of year where longer days and strong sun prevail, it will be a good idea to update the forecast on Friday for the weekend.  And, of course, if anything does change during the week, we will update this forecast.

EXTENDED FORECAST:

Air Quality should remain mostly Good with some scattered Moderates going into the next work week.
