FORECAST DISCUSSION
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.
EXTENDED FORECAST:
There is a potential for poor Air Quality during the end of the week as hot, muggy weather settles in.
