Forecast Discussion: A strong Canadian high pressure system will build into the Mid-Atlantic region for the weekend. It will be unseasonably cool, but dry, with gradual clearing on Saturday and sunny skies on Sunday. Breezy northwesterly winds on Saturday will keep air quality in the Good range. Winds wills shift to the southwest and slacken on Sunday afternoon, allowing for a slight increase in particle concentrations, but very dry air and ample vertical mixing will keep air quality in the Good range. A cold front will approach Philadelphia on Monday. Southwesterly flow ahead of the front and the arrival of warmer air aloft will push particles into the low Moderate range. **Extended Forecast: Tuesday will be mostly sunny. Northwesterly flow behind the cold front will return air quality to the Good range. -Huff
