Mostly cloudy skies and cooler temperatures will limit ozone formation across the First State. In addition, light to moderate east-northeasterly winds will keep smoke west of the Mid-Atlantic region. These conditions will result in Good AQI levels.
Thursday, a trough of low pressure aloft will enhance atmospheric mixing. However, winds will weaken and shift to southerly in the afternoon, reducing pollutant dispersion. In addition, increasing sunshine will aid ozone production. Therefore, AQI levels will be low-Moderate.
Friday, mostly sunny skies and temperatures in the upper-80s will increase ozone formation. In addition, calm to light southerly winds will limit mixing and dispersion. As a result, AQI levels will be Moderate.
DNREC is a member of the Air Quality Partnership of Delaware, which is a public/private coalition of businesses, agencies, and individuals interested in clean air.

Ground-level ozone is a real threat to our health because it reacts with sensitive lung tissue, causing harmful changes in breathing passages. Children, the elderly and individuals with respiratory diseases are especially harmed by ozone. Even healthy individuals can be harmed if they attempt strenuous activity on days with high ozone…those days should be used for inside low physical stress activity.
Remember, this may seem like a small contribution by you as an individual, but if we can get solid public involvement, working together we CAN make a real difference!
