Forecast Discussion: An Arctic high pressure system will build into the Mid-Atlantic region from the west on Thursday, bringing cold and very dry air to the forecast area. Gusty westerly winds will make it feel even colder. Ample atmospheric mixing will keep particles inside the Good range. **Extended Forecast: Winds will diminish on Friday as the center of high pressure moves over the Mid-Atlantic. Particles will rise in response but remain in the Good range due to the very dry and clean air in place. An Arctic cold front will move through the region late Friday, ushering in the coldest air of the winter for the weekend. It will be 20-25 °F below average on Saturday, with gusty winds making it feel bitterly cold. Particles will drop lower into the Good range. -Huff
