Thursday Code Orange Air Quality Action Day in Delaware


Thursday, June 27th, a Code Orange Air Quality Action Day for Delaware!

Because May and early June were unusually rainy, this is the latest into the ozone season that the State of Delaware has ever gone without an ozone Action Day. Weather conditions are finally conducive for high ozone, however. As of Wednesday afternoon, ozone is rising quickly across the state and upwind across the Great Lakes and Ohio River Valley. On Thursday, a second consecutive day of hot and sunny weather, along with a strong sea breeze, will allow ozone to reach the USG range at scattered locations. Particles will linger in the Good range.

 **Extended Forecast: Friday will be even hotter and more stagnant, with calm winds for much of the day. Another Air Quality Action day is expected, with more widespread Code Orange conditions. A cold front will approach the state from the north on Saturday afternoon. Depending on the progression of the front, afternoon showers and thunderstorms are possible, which would limit ozone to the Moderate range. A third consecutive ozone Action day is a possibility, however, if the front slows or thunderstorms are localized
