FORECAST SUMMARY: Friday, November 8, 2024, through Tuesday, November 12, 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:

After enjoying unseasonably warm weather early in the week, things have settled back into more seasonable fall temperatures. 

 High pressure will slide over the Great Lakes region during Friday to begin the weekend weather.  Under sunny skies, afternoon highs will reach the 50’s and clear, dry nights can reach down to the freezing mark.  Air Quality is expected to be Good. 

 As the high pressure ridge quickly exits the region, clouds will roll in late Saturday in advance of an approaching low pressure system.  The front associated with that system will pass through Michigan during Sunday with expected precipitation amounts around a third of an inch.  Although winds will briefly shift to the southwest prior to the frontal passage, Air Quality should remain in the Good range.

 Another, less juicy front, approaches the region on Monday and is expected to be pushed southward over the Great Lakes during Tuesday by a high pressure cell over Ontario.  Not much precipitation is expected with this frontal passage with Air Quality still in the Good category.

Due to the Veteran’s Day holiday on Monday, this forecast will be updated on Tuesday.

  EXTENDED FORECAST:

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