I think it is a good thing for this situation....usually a bad thing though. LOL. If the coastal were going to move Northeast it would be a very bad thing.
Bolded is an important point but not much to explain why Wxbell is higher than TT at the transition zone other than individual algorithms on each suite. Wxbell is the only map I can find that has York City over 4" using 12Z GFS data. Not saying Pivotal is right but Wxbell should not be higher than TT with the same data when the surface maps show sleet/frz will be part of the event.
If you look at the current temps, its already above freezing (surface) at the Jersey Shore including some 40's. Have to keep those easterly's away. Maybe Richmond did not. 850 line looks like it is near Richmond right now.
It would be a nowcasting call like LWX did. Maybe under the premise that even though we lose 850's, there would be a lot more FRZ or Sleet than depicted on models.
