Forecast Discussion: A cold front will move through the Philadelphia metropolitan area overnight on Thursday. Surface winds will be stagnant behind the front, promoting continued buildup of local and wildfire smoke related-particles, for continued Moderate particle concentrations. Partly sunny skies, combined with the very light winds, will be sufficient to push ozone into the Moderate range. **Extended Forecast: On Friday, light winds, stagnant transport aloft, local Independence Day fireworks celebrations, and lingering smoke should keep particles in the Moderate range. Mostly cloudy skies on Friday should lower ozone into the Good Range. Low Moderate particle conditions will likely persist on Saturday as holiday fireworks celebrations continue and the wildfire smoke dissipates throughout the day. Afternoon clearing and light winds will allow ozone to rise, however, clean onshore transport will limit ozone to the Good range. -Huff/Herdt
