FORECAST SUMMARY: Monday,
July 15th, 2019 through Wednesday, July 17th, 2019
AN ACTION DAY ADVISORY REMAINS IN EFFECT FOR MONDAY, JULY 15th IN THE FOLLOWING MICHIGAN COUNTIES...
IN WEST MICHIGAN:
ALLEGAN... KENT... MUSKEGON... AND OTTAWA COUNTIES
Ozone: 8-Hour average Ozone concentrations will be a mixture of Good and Moderate through Wednesday. Several areas may experience USG levels on Monday
PM-2.5: 24-hour average Fine Particulate concentrations will be mostly Good to Low Moderate.
As of noon, Monday’s forecast for elevated ozone in West Michigan and Southeast Michigan looks to be a good forecast. Morning hourly concentrations have been steadily climbing and most of the skies in the southern half of the Lower Peninsula are clear. There are possibilities of pop-up showers, later in the afternoon, but those will be hit or miss.
Tuesday and Wednesday do not appear to be much of a threat for Air Quality as the remnants of Tropical Storm Barry work its way into the Midwest bringing clouds and shower potential.
The three-day stretch of Thursday through Saturday looks to be problematic. It promises to be true summer with high temperatures and humidity with little cloud relief. With the sun as strong as it is during July and light winds, it is easy to imagine that we could see elevated ozone over those days. As such, the forecasters are planning another discussion on Wednesday.
There is a potential for poor Air Quality during the end of the week as hot, muggy weather settles in.
