Forecast Discussion: Saturday will be a seasonably cool and cloudy day. Light winds, combined with some afternoon clearing, may allow for some ozone formation, but clean onshore air mass transport aloft will limit ozone to the Good range. Particles will decrease on Saturday as wildfire smoke dissipates but they will remain in the Moderate range due to Independence Day fireworks celebrations. **Extended Forecast: On Sunday, mostly sunny skies and stagnant surface winds will ensue as a surface high pressure center moves over Pennsylvania. Short, recirculating transport aloft and holiday traffic will push ozone into the upper Moderate range. Moderate particle conditions will also persist as a second pulse of wildfire smoke is expected to impact the Philadelphia forecast area. Mostly sunny skies, light surface winds, and stagnant, recirculating air mass transport aloft will keep ozone and particles in the Moderate range again on Monday. -Herdt/Huff
