Showers and Storms Expected Overnight

A powerful upper-level storm system and associated cold front move through central Virginia tonight, resulting in numerous showers and isolated thunderstorms across the area. The strongest storms will produce small hail and wind gusts to 30 mph as well as occasional lightning. Much colder air will be moving into the area after midnight, and the rain could change to or mix with a few snow flakes before ending. If this were to occur in the Richmond metro area, the most likely time would be between 3 AM and 6 AM. All precipitation will come to an end around sunrise Friday, with mostly sunny and blustery conditions expected during the day.

Fog Update


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.

Dense Fog Advisory Thanksgiving Morning


A Dense Fog Advisory is in effect until 9 a.m. for all of Central Virginia this Thanksgiving Morning. Northern Virginia into the D.C.-Baltimore areas will remain under the Dense Fog Advisory until Noon. The combination of damp ground from days of drizzle and showers, clearing skies overnight, and calm winds has led to many areas of dense fog developing. Visibilities widespread are below a half-mile, with many spots reduced to a quarter-mile. Conditions should improve mid-morning. Please use extra caution traveling this morning, allowing extra time to get to your destination, and also keeping your headlights on the low-beam setting. Here is the Richmond view from our Dominion Cam downtown. It looks more like San Francisco than Richmond!
