I think at this point it is not out of the realm that some people in the LSV stay all snow based on the lack of advance in the "sleet line" still south and east of Washington. Once the forming coastal takes more influence it will push that line north but models have busted, even HRRR, in doing it too fast so any data after that bust is also suspect. Just a thought. The GFS depiction was a total failure for the Mid Atlantic.
