Forecast Discussion: A cold front will move slowly through the Philadelphia metropolitan area on Wednesday. Clouds, rain showers, and scattered thunderstorms ahead of the frontal passage will return ozone to the Good range. Particles will remain in the Moderate range in response to lingering Canadian wildfire smoke. **Extended Forecast: On Thursday, mostly cloudy skies and scattered rain showers and thunderstorms will continue as the front stalls along the Mason-Dixon Line. The clouds and precipitation will limit ozone to the Good range, while particles will linger in the low Moderate range. Ozone will rebound into the Moderate range on Friday as surface high pressure builds into the forecast area, promoting sunny skies and light winds. Less humid air will allow particles to fall in the Good range. -Huff/Herdt
