FORECAST DISCUSSION:
A warm front will lift northward through Michigan tonight into Wednesday. During Wednesday, clouds and showers are expected in the northern and eastern areas, however, southwestern counties should be cloud free, hot and humid. Add the atmospheric smoke from the western fires and those southwestern counties are prime for elevated ozone.
As a result, an air quality advisory has been issued in West Michigan from the Indiana border up to Muskegon.
Thursday could be a continuation of elevated ozone, the forecast will be revisited Wednesday morning to make that determination.
EXTENDED FORECAST:
Air Quality will stay mostly Good to Moderate with USG possible in West Michigan.
