So, you think it is all snow? NAM is usually good with showing warm noses, or so I have been told a few times over the years. NAM was right with the warm nose each time.
Never bet against the ECMWF. NAM and other models appear to be caving slowly to ECMWF and UKMET. IMHO
As I have mentioned before, temps appear to be an issue. Rates may not overcome it.
Until the ECMWF gets on board I will be very skeptical. Never bet against it, I have seen so many instances of it being right over all the other models.
