As of 4:30 a.m. Wednesday, here is the updated Winter Storm Warning and Advisory map for central Virginia:
Rain is falling in most of central Virginia right now, with the only locations receiving snow in northern Virginia around Fredericksburg and locations north and west. Surface temperatures where the snow is falling are still just above freezing, so much of this is likely melting as it reaches the ground, other than accumulating some on the grass and other elevated objects. We still expect periods of rain through the day Wednesday, so keep your umbrella handy. Deeper, colder air will begin surging into central Virginia this evening from west to east as our low pressure system tracks east and northeast of Virginia's coast, pulling that colder air into our region. As this colder air arrives, rain will change over to snow, which will be heavy and wet at times. The changeover to snow should begin in the western Richmond metro area beginning at 5 p.m., with the eastern Richmond metro at all snow as well by 8 p.m. This means that a heavy, wet snow may be falling in the metro during the Wednesday evening commute. Please prepare extra time to get to your Wednesday evening destinations, and be careful driving in what will likely be reduced visibilities because of the snowfall. Temperatures while this snow is falling will still be just above freezing, so some of this will be melting as it hits the roads. Here's what we expect for wet snow accumulation:
The snow should end in the entire area by 3 a.m. Thursday, but surface temperatures will dip below freezing into the upper 20s, allowing many icy patches to develop on any pavement. This will impact the Thursday morning commute with slick and hazardous conditions.
