Forecast Discussion: The recent short period of seasonable Spring-like weather will come to an end on Friday as a strong cold front moves through the Philadelphia metropolitan region around midnight. Rain and possibly a thunderstorm will accompany the frontal passage and continue overnight into Friday morning, with clouds lingering throughout the day. The front will usher in a clean, cooler, and less humid air mass on breezy northwesterly winds, for a return to Good air quality. **Extended Forecast: Good air quality will continue over the weekend. The Canadian air mass will fully build into the Mid-Atlantic region, keeping temperatures below average, with dry conditions. It will be partly cloudy on Saturday, with gradual clearing to sunny skies on Sunday as surface high pressure moves over the Mid-Atlantic. Breezy northwesterly winds will keep particle concentrations well inside the Good range on Saturday. Particles may rise slightly toward the upper Good range on Sunday in response to lighter and recirculating winds (northwesterly to southwesterly), but the dry, unmodified air mass will keep concentrations within the Good range. -Huff
