National Weather Service still not that impressed with any of the changes.

.UPDATE...
No major changes planned to the overnight forecast. However, will
be lowering the New Year`s Day temperatures slightly, based on
latest guidance and the strength of the post-frontal cold
advection now occurring in OK. With low clouds and a biting north
wind, much of the northwest half of the forecast area will remain
entrenched in the 30s all day tomorrow.
No changes planned to the current Winter Storm Watch
configuration. New NAM guidance doesn`t immediately suggest a need
to expand the watch, but does support the pre-advertised threat of
appreciable freezing rain in our west central counties Wednesday.
The greater DFW Metroplex still appears to lie on the interface
between quasi-freezing temperatures and appreciable rainfall
Wednesday. Ice on elevated surfaces, and perhaps some bridge
decks, remains a distinct possibility Wednesday morning,
particularly in Denton, Tarrant and Johnson Counties.
Considerable uncertainty remains, however, as to how the near-
surface temperature profiles Wednesday will be modulated by: 1)
cold air advection, 2) diabatic processes associated with the
evolving precipitation, and 3) surface soil temperatures. We
should have more clarity on these factors, as well as the
evolution of the precipitation shield itself, by tomorrow.
