FORECAST SUMMARY: Monday, November 4, 2024, through Friday, November 8, 2024

OZONE:

November marks the end of the 2024 ozone season. The 2025 ozone season will begin on March 1st.

 PM-2.5:

24-hour average Fine Particulate concentrations are expected to be mostly Good (AQI Green).

FORECAST DISCUSSION:

As we enter the first full week of November, ozone season is now complete, and we focus solely on PM-2.5.  Wildfire smoke does not appear to be an issue with the number of fires in western U.S. and Canada greatly reduced.  In fact, the smoke models are not showing any significant smoke, anywhere. 

 The particulate models are still showing some areas of Low Moderate PM-2.5 so I will keep Moderate in the forecast for the lower half the Lower Peninsula, during Monday.  But then it clears out and I expect Good Air Quality for the remainder of the forecast period.

 In terms of the weather outlook, it looks to be very wet through Tuesday and into Wednesday morning.  Moist southerly winds are bringing in high potential rainfall amounts, up to 3” in some areas of western Michigan.  The rain looks to be joined by strong winds during election day (Tuesday).  The wet weather will eventually end on Wednesday and things will dry out under sunny skies for Thursday and Friday.

  EXTENDED FORECAST:

Air Quality is expected to remain Good going into the upcoming weekend.
