An Ozone Action! Day Advisory is being issued for Thursday, July 3rd

An Ozone Action! Day Advisory is being issued for Thursday, July 3rd


Weak high pressure will continue to hold back a frontal boundary currently located in the northern plains states. This will provide most of Michigan with partly cloudy skies and hot temperatures, warming to the mid to upper 80's. The exception will be the Upper Peninsula, where some shower and thunderstorm activity is developing ahead of a stationary frontal boundary located in Canada. This activity should stay north of the southern Lower Peninsula of Michigan, however. Meanwhile, an upper-level disturbance could spark off an isolated thunderstorm or two in the southern Lower Peninsula. But most areas will continue to be hot and dry, with light and variable winds and party cloudy skies. Thursday winds will pick up in speed and become more southwesterly. This will also help nudge the temperatures up a degree or two, with maximums around the 90 degree mark, and partly cloudy skies. As the frontal boundary to our west approaches, there will be an increasing chance of precipitation as we head into Friday.


8-hour ozone concentrations, which had an AQI of moderate at most locations on Tuesday, will rise today and tomorrow. Our current airmass is stagnant and is cut off from any organized flow. Expect 8-hour ozone concentrations to reach an AQI of moderate today, with several areas experiencing an AQI of unhealthy for sensitive groups. This will be especially true along the Lake Michigan shoreline. If you are sensitive to ozone, please take all necessary precautions to ensure your health. At this time, Thursday poses the greatest threat for elevated ozone levels, with the likelihood of widespread 8-hr concentrations with an AQI of unhealthy for sensitive groups. Therefore, an Ozone Action! Day advisory is being called for both West and Southeast Michigan for Thursday, July 3rd. Should rain be evident in Friday's forecast, an improvement in the air quality is possible. This forecast will be reevaluated tomorrow to utilize the latest meteorological data in making a forecast for Friday.

Mohammed Kubaisi, 12, was fatally shot in the chest on the roof of his home in Baghdad by a U.S. soldier.  Mohammed's father, unlike his mother, said he was not ready to call for revenge, but expressed astonishment that the U.S. military had not apologized for killing his son.    "I want to speak to the man who killed my son, and I want to speak to his superior," he said. "That is our tradition. We must speak."
