Forecast Discussion: Autumn will finally arrive in the Delaware Valley this weekend. A cold front will move though the forecast area early Saturday morning, putting an end to this week’s period of unseasonably warm weather. The front will usher in a cooler and much drier Canadian air mass on northerly winds. Temperatures will drop to around average for this time of year on Saturday and persist through Monday morning. Clouds will accompany the front, but give way to sunny skies on Saturday afternoon that will continue through Monday. In all, it will be delightful early autumn weekend for the region. The arrival of the clean Canadian air mass will return ozone and particles to the Good range on Saturday, where they will remain through Monday. **Extended Forecast: The next cold front will move through the Philadelphia metropolitan area on Tuesday. It will be cloudy with periods of rain. Ozone and particles will remain in the Good range. -Huff
