FORECAST SUMMARY: Friday, September 27, 2024, through Monday, September 30, 2024
OZONE:
Ozone concentrations will be Good (AQI Green)..
PM-2.5:
PM-2.5 concentrations are also expected to be mostly Good (AQI Green).
FORECAST DISCUSSION:
Friday is expected to stay mostly dry under high pressure with continued Good Air Quality. However, as the remnants of Hurricane Helene travel northwards and begin squeezing that high pressure ridge, winds will increase with some significant wind gusts.
An upper level low over Tennessee will merge with the remnants of Hurricane Helene. That will send moisture into southern Lower Michigan, tonight, and should be enough to generate light showers throughout the weekend.
High pressure will attempt to build back in Sunday night into Monday, ahead of a cold front on track to move through on Tuesday.
During this time, Air Quality is expected to remain Good, throughout the state.
EXTENDED FORECAST:
Air Quality is expected to remain Good going into the upcoming work week.
