The Dense Fog Advisory has expired for most of Central Virginia, but does remain in effect for the counties highlighted in orange until Noon. This does include the cities of Fredericksburg, Charlottesville, and Staunton. A Ground Stop program is still in effect for DCA, BWI, and IAD, and will likely remain in effect until late morning or mid-day. Click here for the latest on those airports. Elsewhere in Central Virginia, patchy fog will linger until late-morning, when visibilities should be much improved.
