Enviro-Mich message from "Alex J. Sagady & Associates" <email@example.com>
Yesterday (Thursday) wasn't an ozone action/warning day, but the atmosphere
of northwestern Michigan and the Upper Peninsula got the better of
MDEQ air pollution meteorologists on Thursday.
Unhealthy for Sensitive Groups -- Code Orange--- ozone air pollution
ranged from Muskegon to Seney in the Upper Peninsula on Thursday. A noteworthy
air pollution event -- to the best of this commentator's knowledge,
yesterday was the first USG ozone event over 85 ppb ever to be detected by
the Peshawbestown ozone monitor in the Leelanau Peninsula (subject to
later validation). This monitor is operated by the Grand Traverse Band of Ottawa and Chippewa
on Thursday...8 hour averages over 85 ppb, the level of the ozone standard
Seney National Wildlife Refuge 97 -- upper peninsula
all data is unvalidated...
Today (Friday), however, is an ozone action day in West Michigan
At Grand Rapids at 9:13 AM this morning, monitoring is
showing Unhealthy for Sensitive Groups for PM 2.5, although
MDEQ has a generic advisory up that their monitors can be reading
high or low because of technical problems.
GREAT NEWS!!! There is now operating a
Detroit, MI Midwest HAZECAM....here it is...
The Cam seems to be located just downriver from Cobo
hall.... Note that this morning you cannot see clear details
on Belle Isle, just a short distance away because of haze.
This Detroit cam in Michigan is in addition to Seney's cam at
Here is ozone/PM2.5 forecast content from MDEQ for Friday....

THIS INCLUDES THE FOLLOWING COUNTIES IN WEST MICHIGAN...ALLEGAN...BERRIEN...CASS...KENT...MUSKEGON...OTTAWA...VAN BUREN.
Michigan Air Quality Forecast
Thursday, June 23rd, 2005 through Friday, June 24th, 2005
OZONE: 8-hr concentrations are forecasted to be in the Moderate range state wide on Thursday. Readings Friday will be in the Unhealthy for Sensitive Groups (USG) range across West Michigan with levels in the Moderate range across the rest of the state.
PM-2.5: 24-hr concentrations are forecasted to be in the Moderate range.
Southwest winds on the backside of a high pressure area off to our southeast will bring unseasonably warm temperatures into Michigan to end the workweek. High temperatures well into the 80s today will be in the 90s across much of the state tomorrow. Along with warm temperatures, plenty of sunshine will also be seen the next two days.
With a west to southwest surface and upper level wind flow, our pollutant levels will also be on the increase. Ozone levels will be in the Moderate range today and isolated readings in the Unhealthy for Sensitive Groups (USG) range is not out of the question. More widespread USG Ozone levels will be seen across West Michigan tomorrow, therefore, an Ozone Action Day has been issued for tomorrow across that area. Ozone readings should stay in the mid to high end Moderate range tomorrow across the rest of the state. PM2.5 levels will be in the Moderate range today. Levels in the mid to upper Moderate range can be expected tomorrow.
A cold front will move in from the north late Friday, into Saturday. This will bring us a chance for scattered storms to start the weekend. Ozone levels should drop down into the Good range Saturday with the increased cloud cover and slightly cooler surface and upper level temperatures. PM2.5 concentrations Saturday will remain in the Moderate range.
By Sunday it looks like our winds switch back to the southwest bringing us another round of unseasonably warm temperatures early next week. This will again bring us the chance for elevated readings of both Ozone and PM2.5.
