If you were to mix the precip from the GFS with the timing and magnitude of the nam's cold, The Metroplex might be in trouble on Sunday.
This is a good observation. If the GFS is off on it's placement by just some you have a very heavy winter precip event.
0z GFS stacks the cold air like crazy. This air mass is just going to plow.
But the enhanced convection appears to be caused by frontogenetic forcing directly behind the frontal boundary (still above freezing). I would expect this heavy precip boundary to be further south if the models are underestimating the speed of the front.
