Low clouds and patchy fog will persist through mid-morning. A few showers will track northeast through central Virginia this morning as moisture surges in from the southwest, but the main story for today will be the big warm-up resulting from that southerly flow. Highs this afternoon will surge into the upper 60s and lower 70s, despite mostly cloudy skies much of the day.
Low temperatures Thursday night into Friday morning will again be very mild for early December, only falling into the low to mid 60s (which is close to record-warm low temperatures for December 6: the record to tie is 60 degrees from 1998). Friday will be another warm day, with highs reaching upper 60s (northern half of Virginia) and lower 70s (southern half of Virginia).
A strong cold front will move through the area Friday evening, bringing a good chance of rain to the area, followed by much colder air Saturday. Although there may be some scattered light rain showers during Friday, the best rain chances will occur along and behind the cold front in Richmond after 8 p.m. through early Saturday morning. It looks to me right now that most of the rain will move into southside Virginia and Hampton Roads by Saturday sunrise, with only slim rain chances for the remainder of the day. That's great news for the Dominion Christmas Parade from the Science Museum of Virginia along Broad Street! But it will be chilly as colder air plunges into the Commonwealth, so dress in layers and prepare for cold wind chills in the low to mid 30s. Highs Saturday will occur in the early morning hours, with slowly falling temps throughout the day into the low 40s.
Very cold and dry air will continue to settle into the region early Sunday as strong high pressure moves through the Northeast states, sending us a northerly breeze. An upper-level storm system will move into the Mid-Atlantic from the southwest on Sunday, spreading precipitation over most of the Commonwealth. Low-level cold and dry air from the Northeast high will be in place as the precipitation falls, resulting in an extended period of freezing rain and sleet for roughly the western two-thirds of Virginia.
The extent and strength of the cold air and the total amount of precipitation is less certain for central Virginia, but model data continues to suggest the likelihood for a significant icing event for western and northwestern Virginia. Warmer air will overspread the area at all levels of the atmosphere during the day Sunday, converting all of the sleet and freezing rain to rain by the afternoon (it will take longer to change the farther north and west you are).
Temperatures will continue to warm into Monday, with scattered showers and highs in the upper 50s and low 60s. Another strong cold front will move through the area next Tuesday, bringing a good chance of rain to the region, followed by a couple of days of cold and dry weather.
