Forecast Discussion: Autumn will finally arrive in the State of Delaware this weekend. A cold front will move though the state on 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. Clouds will accompany the front, but give way to sunny skies late Saturday afternoon that will continue through Monday morning. In all, it will be delightful early autumn weekend. 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 state on Tuesday. It will be cloudy with periods of rain. Ozone and particles will remain in the Good range. -Huff
