Forecast Discussion: Tuesday will be warm, with increasing clouds in the afternoon ahead of a slowly approaching cold front. There is a chance for isolated thunderstorms in the afternoon as well. Cloud cover will limit ozone to the upper Moderate range. Particles will remain in the Moderate range as well in the modified air mass. **Extended Forecast: A cleaner and slightly cooler air mass will build in on Wednesday behind the front. Lingering clouds will help to suppress ozone to the Good range, while particles will remain in the Moderate range. Winds aloft and at the surface will shift onshore (northeast/easterly) on Thursday, bringing clean maritime air into Philadelphia for Good ozone and particle concentrations. -Huff
