18z Euro is a bit further north so far this run from 12z, A bit less confluence and higher heights out ahead, Still ends up a bit better on qpf then 12z.
12z HRRR is very bullish, I've had an eye on the models for Friday for a few days, They have been ticking colder and i made the comment in the other thread that i would probably see more snow Friday then the Sun-Mon event.
