FORECAST SUMMARY: Tuesday, July 31st, 2007 through Wednesday, August 1st, 2007

OZONE: 8-hour concentrations are expected to be Upper Good to Low Moderate Tuesday. Levels will be Moderate to Unhealthy for Sensitive Groups (USG) on Wednesday.

PM-2.5: 24-hour concentrations are expected to be in the Moderate range through Wednesday.

FORECAST DISCUSSION:

Temperatures soared into the 90s on Monday; however, air quality levels remained mostly Good across the state. This will not be the case in the next few days; however. Hot conditions will continue through mid-week as the high pressure that was talked about Monday slides overhead then further east by Thursday. As the high slides east the wind flow will change to the south/southwest starting Wednesday. Hot conditions, southwest winds and plenty of sunshine will help create an environment conducive for Ozone development. Therefore, an Ozone Action Day has been issued for Wednesday for parts of west and southeastern Michigan.

The threat for elevated Ozone levels could linger Thursday as stronger southwest winds develop ahead of a weak front forecasted to pass the state late in the day. The stronger wind flow will aid in the transport of pollution from northern Illinois/Indiana to West Michigan. Plus, there is not much moisture with this front so plenty of sunshine and hot temperatures will continue Thursday. Conditions will be reviewed again on Wednesday to decide if the Ozone Action Day will be continued into Thursday.

PM2.5 levels were ranging in the upper Good to middle Moderate range on Tuesday and these readings were slowly increasing. A continued climb in PM2.5 is expected with levels statewide in the Moderate range by Wednesday.

EXTENDED FORECAST:

Without a clean air mass change expected over the next few days these conditions may persist into the weekend. The next stronger cold front should pass the area late Saturday/early Sunday. Until then we will be keeping a close eye on the air quality for Michigan.
