Forecast Discussion: A weak, quick-moving cold front will move through Philadelphia early Tuesday, bringing clouds and scattered showers to the area in the morning. Skies will clear by the afternoon as surface high pressure centered over the Midwest builds across the Mid-Atlantic region. Particles will rise in the morning in response to light winds and high atmospheric humidity, but breezy afternoon winds and the arrival of a reinforcing pulse of cool, dry, and clean air will keep air quality in the Good range. **Extended Forecast: Wednesday and Thursday will be mostly sunny with light winds and slightly below average temperatures under the influence of dominating surface high pressure. Despite the stagnant surface winds, the clean and cool regional air mass will limit both ozone and particles to the Good range. -Huff
