Forecast Discussion: A quick-moving Clipper system will pass just to the north of Delaware overnight and bring the chance for a light wintery mix of precipitation across the state. Very cold and dry Arctic air will filter in behind the departing system during the day on Friday. This reinforcing surge of dry air and gusty northwesterly winds will keep air quality in the Good range. **Extended Forecast: The Arctic air mass will keep its grip on the Mid-Atlantic region on Saturday. It will be sunny but bitterly cold and windy. Good air quality will continue. There is uncertainty in the forecast for Sunday. Another low pressure system may bring a new round of snow to Delaware late Sunday into Monday. Limited vertical mixing and light surface winds ahead of the storm will allow particle concentrations to rebound to the Moderate range. -Huff
