A Cold Rain For Most...


Surface temperatures remain in the 50s this afternoon, but will slowly lower into the mid and upper 30s by morning as colder air oozes in from the north. This colder air will continue to inch its way in tomorrow, but warmer air aloft will mean mainly rain for central Virginia. In the Metro Richmond area, we expect a cold rain, with afternoon temperatures mainly in the upper 30s. Off to the northwest, the fact that surface temperatures have been higher today will probably alleviate the threat for freezing rain tomorrow, however, as the cold air leaks in, a shallow layer of it could help to produce periods of sleet from Charlottesville up to Fredericksburg. I don't expect major problems in these areas though, with any significant issues confined to the Blue Ridge, Shenandoah Valley, and just north and west of Washington, DC.

Get ready for a significant amount of rain though, with the model data showing the potential for a good 1 1/2-2 1/2 inches by Wednesday afternoon (see the forecast graphic from the National Meteorological Center above). There remains the possibility of a few passing snow flurries or showers on Thursday, as an upper level trough swings across the Mid-Atlantic.
