Michigan Air Quality Forecast

Tuesday, August 2nd, 2005 through Friday, August 5th, 2005 

OZONE: 8-hr concentrations Tuesday and Wednesday are forecasted to be in the USG range along the western shoreline with readings across the rest of the state in the Moderate range.  Levels will be in the Good range statewide Thursday and Friday.

PM-2.5: 24-hr concentrations are forecasted to be in the high Moderate to middle USG range on Tuesday and Wednesday.  Levels will be in the Moderate range Thursday and in the Good range Friday.  

Forecast Discussion:
Surface high pressure and upper level ridging will continue today.  Southwest winds will usher in hot temperatures with highs today and tomorrow forecasted to be in the 90s.  The surface high pressure and upper level ridge will begin moving off to the east on Wednesday.  Michigan will see an increase in high and mid clouds during the day Wednesday as a shortwave moves into Wisconsin.  The clouds, however, won't make it into West Michigan early enough to stop elevated Ozone levels.  Therefore, an Ozone Action Day has been issued for tomorrow for the western lake shore areas from Ludington south to New Buffalo.

A cold front located in the Midwest will make its way east bringing Michigan more in the way of clouds and the chance for precipitation starting in Western Upper Michigan late Wednesday.  As the front moves from northwest to southeast, the chances for rain will increase across Lower Michigan during the day Thursday.  The cold front will exit southeast Michigan early Friday with high pressure building in behind it.  This high pressure area will stick around for most of the coming weekend.

Because of the stronger southwest winds today, warm upper level temperatures and lack of cloud cover, there is currently an Ozone Action Day in effect along the western lakeshore.  Conditions for elevated Ozone levels continue for tomorrow; therefore, the Ozone Action Day is extended through then.  PM2.5 levels currently in the upper Moderate to low USG range will remain there through Wednesday.

Increased clouds and the chance for rain on Thursday will end the elevated Ozone episode.  Ozone readings will fall back into the Good category for Thursday and Friday.  As the cold front moves through on Thursday, PM2.5 levels will also start decreasing.  Readings Thursday will be in the Moderate range with levels Friday down into the Good category.

Extended Forecast:
High pressure looks to remain in control of our weather this coming weekend.  Southwest winds develop on Sunday as the high moves off to our east and a cold front approaches from the west.  Along with that, upper air temperatures will be increasing.  Considering Michigan will remain under the same air mass through the weekend, both Ozone and PM2.5 levels could begin climbing on Sunday.
