Forecast Discussion: Canadian high pressure will spread southward over the Mid-Atlantic region on Friday, bringing a delightful pulse of cool and dry autumn air into the Philadelphia metropolitan area. The combination of this clean air mass and breezy onshore (northeast/easterly) winds will keep air quality well in the Good range. **Extended Forecast: The center of surface high pressure will move offshore to the northeast for Saturday and Sunday, and a cold front will approach from the northwest. In response, winds will become southerly, which will bring warmer and more humid air into the region. Southeasterly onshore flow will keep air quality in the Good range for the weekend, with higher ozone and particle concentrations on Sunday, when high temperatures will reach into the low 80s °F. -Huff
