Your backyard is seeing favorable trends with the coastal. DC/NOVA isn’t, at least with the 00z suite so far except the CMC which just got NOVA into the coastal.
The initial slug of moisture from the WAA going south isn’t necessarily indicative of the coastal deepening in a great location for NOVA on north...they are two separate things.
That is more dependent on the orientation of the trough, strength of 500 low, etc. At least I think.
