I'm getting old, I can't remember things that well, anymore, but I'm sure it's happened before. The surface temps are very marginal, but it's cold enough to very cold as we head up into the atmosphere. The overall tilt/structure of the system is going to be important, especially when it comes to any wraparound precip. I think the Euro wasn't that impressive while the GFS was pretty impressive in that regard. It'll change as the energy for this system is still out in the Pacific and won't be over land until late Thursday it looks like.
