Looks like the Euro/EPS have screwed the pooch on this one & have been behind the curve from the onset. Everyone that was worried about having this model on board before seriously believing this threat have egg on their face. It was honestly kind of strange to see the EPS and Euro more progressive with the northern stream than the GFS a few days ago, it’s almost always the other way around, this fact certainly left me scratching my head. Moral of the story here: no matter how good a model and its ensemble suite are, they are never infallible & it’s rarely a good idea to put all or even a majority of your eggs into one basket.
This looks like a very legit threat for the I 40 corridor (TN, NC, upstate SC, and VA), Warm advection, isentropic upglide, & frontogenesis will be the primary forcing agents for ascent here, most of the time global models will low ball the magnitude of one, two, or all of the above due to their coarse spatiotemporal resolutions, leading to more widespread and intense precip verifying
