Forecast Discussion: FORECAST SUMMARY: Friday, September 23rd, 2016 through Monday, September 26th, 2016 Ozone: 8-hour Ozone values are expected to be Good. PM-2.5: 24-hour Fine Particulate concentrations will range from Good to low-Moderate Friday, then Good the rest of the period. FORECAST DISCUSSION: Moderate ozone and fine particulate readings on Thursday across much of Lower Michigan will improve to the Good range Friday as a cold front sinks south of the state. Cleaner air will filter in on a northeast wind. Fine particulate may linger in the Moderate range in the southeast corner of the state; otherwise, pollution levels will be Good. High pressure tracking south from Canada Friday will position itself over Ontario Saturday bringing in cooler air. East/southeast winds will keep air quality Good for both ozone and fine particulate. On Sunday, winds pick up in speed from the south/southwest ahead of an approaching cold front. With a low background of pollution in place, Good air quality will likely continue. EXTENDED FORECAST: Extended forecast models show a cold front passing the state late Sunday into Monday bringing in the chance for rain and storms. Precipitation chances will linger into mid-week as an low pressures area positions itself north of Lake Superior. Good air quality is expected to continue into next week.
