Forecast Discussion: A cold front will move through the Philadelphia metropolitan area Thursday evening. Pre-frontal clouds and scattered showers and thunderstorms in the afternoon will help to limit rising ozone, yet low Moderate ozone will ensue as partly sunny skies persist throughout much of the day. Increasing humidity will allow particles to rise higher into the Moderate range. **Extended Forecast: On Friday, surface high pressure will filter into the forecast area behind the passage of the cold front. Despite sunny skies and light winds, the arrival of a cleaner, drier air mass will return ozone and particles to the Good range. Ozone will rebound into the Moderate range on Saturday as another day of full sun, light winds, and pollutant build-up occurs. Particles will remain in the Good range in response to the dry air mass. -Herdt/Huff
