Forecast Discussion: A pre-Thanksgiving coastal storm will impact the Philadelphia metropolitan area on Wednesday. Please monitor the National Weather Service (NWS) for information related to the storm, which is expected to cause major travel delays during the day on Wednesday. Several inches of wet snow are expected to fall across southeastern PA. This wintery precipitation, along with breezy northerly winds, will keep air quality in the Good range. **Extended Forecast: Particle concentrations will rise into the Moderate range on Thanksgiving Day due to light winds and limited vertical mixing caused by accumulated snow on the ground. On Black Friday, surface high pressure will build in from the west, bringing a return of mostly sunny skies. It will be cold and brisk, with air quality lingering in the low Moderate range. -Huff
