Forecast Discussion: A weak cold front will slowly move through the Philadelphia metropolitan region overnight. Clouds and a chance of scattered showers will last through the morning, with clearing in the afternoon as the front pushes away to the south. Particle concentrations are falling rapidly upwind, and the arrival of this clean air, along with steady northerly winds, will be sufficient to keep particle concentrations inside the Good range on Wednesday. **Extended Forecast: On Thursday, persistent transport of clean air aloft from the Gulf of Maine will keep particles in the upper Good range. A strong cold front will approach from the west on Friday. Breezy southeasterly winds ahead of the front will keep particle concentrations along the Good/Moderate threshold. -Huff
