Forecast Discussion: A weak cold front will move through Delaware overnight, bringing cleaner, cooler, and drier air for Thursday. Sustained northwesterly winds will promote mixing and a return to Good air quality. **Extended Forecast: Winds will slacken on Friday as the center of surface high pressure moves just to the north. Light and recirculating surface winds and sunny skies will allow ozone and particles to rebound, but they will remain in the Good range. A warm front will bring warmer and moister air into Delaware on Saturday. Moderate air quality is expected, although light onshore flow may suppress rising pollutant levels. -Huff
