You know hot as it was last summer and stagnet i dont remember having any of them either but today this area had one as well most of Ohio and Michigan as well...................Had code reds except in Cleveland where they had orange.......

I know exactly what you are talking about, Harry. The fact that we've had summers with stagnant high pressure ridges and extreme haze sets up due to a strong temperature inversion. The contaminent air is trapped down in the lowest layers of the atmosphere ... I've seen the news media and WFO's advise people about dangerous air qualities but never issued as an official advisory in this format ... especially in South Carolina ...

It's bad here in the Atlanta area guys. I began wheezing around 1 p.m. -- normally that doesn't occur until around 4 or 5 (when the ozone level peaks...then falls after sundown, and I stop wheezing).

What's alarming to me....it only reached 87 degrees at my location; and we've had plenty of rain. If we're reaching code red now, what lies ahead in July in August on those 95-100° afternoons, especially if rainfall is below average? (allowing pollutants to build up and the air to really become stagnant).
