Forecast Discussion: A cold front will pass through Delaware on Thursday, triggering cloud cover and scattered precipitation, mainly in the morning. The front will bring in a relatively cool and dry air mass along with northwesterly flow. Air quality will be limited to the Good range. **Extended Forecast: Friday will be a beautiful day with sunny skies and light winds as high pressure builds into the area. An afternoon sea breeze and a recirculating surface winds will allow ozone and its precursors to accumulate, bringing ozone concentrations into the low Moderate range. Low atmospheric moisture will keep particles in the Good range. Saturday will be similar to Friday in regard to the nice weather and sunny skies. Early morning stagnation and westerly transport aloft will allow for Moderate air quality. -Catena/Huff/Herdt
