Forecast Discussion: Surface high pressure will make a brief return on Thursday, bringing mostly sunny skies to the Philadelphia metropolitan area. Light but persistent north/northeasterly surface winds and transport of clean air aloft from the Gulf of Maine will keep particle concentrations in the upper Good range. **Extended Forecast: A strong cold front will approach from the west on Friday. A period of stagnation in the morning will allow particles to accumulate, but continued onshore transport aloft and stronger winds in the afternoon will keep daily average particle concentrations inside the Good range. Rain and clouds will accompany the passage of the cold front on Saturday morning. Breezy winds and the arrival of a cooler and drier air mass will push particles lower into the Good range. -Huff
