Forecast Discussion: Friday will be seasonably warm and mostly sunny. Light and recirculating surface winds will promote the accumulation of pollutants along I-95. Carry-over of clean conditions from Thursday will help to limit rising ozone, but isolated locations will reach the low Moderate range on Friday. Particles will remain in the Good range due to low atmospheric humidity. **Extended Forecast: Heat and humidity will return for the Labor Day weekend. A warm front will move through Philadelphia on Saturday, bringing warmer and more humid air in its wake. There is some uncertainty regarding the amount of cloud cover associated with Saturday’s front and a series of disturbances that will move over the area on Sunday. Increasing clouds are expected on Saturday afternoon, with the possibility of mostly cloudy skies on Sunday. Particles will progressively rise into the Moderate range, while ozone will depend on cloud cover, with Moderate conditions most likely at this point. -Huff
