Forecast Discussion: Hot, humid, sunny, and stagnant weather conditions will continue on Wednesday, making it feel more like early August than the first week of September. Although these conditions are conducive to ozone formation, ozone concentrations are rising slower than expected as of 2 PM on Tuesday. As a result, only upper Moderate ozone conditions are expected on Wednesday, but isolated Code Orange (USG) ozone is possible, especially in northern Delaware. Particles will remain in the mid-Moderate range in response to humidity and remnant smoke transported from the western U.S. wildfires. **Extended Forecast: A weak cold front will arrive from the north on Thursday afternoon, but it is not expected to substantially impact air quality, allowing Moderate ozone and particles to continue. By Friday, winds shift onshore (northeasterly), bringing cooler air into the state. There is also a chance for afternoon thunderstorms. As a result, ozone will drop to the upper Good range. Particle concentrations will also drop but remain in the Moderate range. -Huff
