One thing that stood out to me with the 00z Euro is that the northern edge of the QPF field has really been eaten away the last couple runs, with northern MD now running from 0.3-0.5" total for the duration, with similar decreases down to just about a line from Alexandra/Warrenton. The area south of that has remained pretty steady, so to me it seems the goalposts are beginning to narrow on keeping the most moisture in central VA. We have time, but I'm not sure we'll see any huge adjustments, though even just a 20-mile shift in that northern edge will make a huge difference for a lot of folks.
Edit: The 6z euro map shows exactly what I was talking about. Northern edge is getting gobbled up.
