Forecast Discussion: Surface winds will stagnate on Thursday morning as surface high pressure slides over the Mid-Atlantic region. Increasing clouds in the afternoon and a morning surface inversion will limit vertical mixing as well. Consequently, particle concentrations will make a sharp rebound into the Moderate range. **Extended Forecast: A fast-moving Clipper system will arrive overnight Friday and bring the chance for a dusting of snow across the state. Breezy northwesterly winds will provide ample ventilation and return air quality to the Good range. Very cold and dry Arctic air will build into the Mid-Atlantic on Saturday. It will be sunny but bitterly cold and windy. Continued brisk northwesterly winds and low atmospheric humidity will extend Good air quality. -Huff
