Forecast Discussion: Surface high pressure will build into the Philadelphia metropolitan area on Saturday. Ozone production will increase due to mostly sunny skies, yet steady westerly winds and deep vertical mixing will limit ozone to the Good range. Particles will remain in the Good range as well in response to continued low humidity. **Extended Forecast: Full sun combined with deteriorating winds on Sunday will allow both ozone and particles to rise into the low Moderate range. On Monday, a cold front will approach the forecast area. Clouds and rain associated with the front will not reach Philadelphia until the evening, allowing ozone to remain in the Moderate range for another day. Particles will climb further into the Moderate range due to increasing humidity. -Herdt/Ryan
