I agree with your thoughts to a tee.

As do I. I'm just saying to those who live run to run, that models are just complex algorithms set up to potentially show what physics in the atmosphere will do. Each model has its biases and its strengths. That is why with this type of storm especially, models need to be looked at very closely to see why they forecast what they do. This is why a forecaster needs extensive training and to be very knowledgeable in both physics and mathematics. Mainly this is why forecasters make forecasts and not computer models.

The NAM being too warm for those area would throw it off that much??? I don't understand how.. That just explains why it was so warm.. Any thoughts?

Higher temperatures = higher heights = more amplified = further west = positive feedback towards even more warmth than the initial 2-3 C error would indicate.

Anyone also very very impressed with the radar down south ?   This thing is rich with moisture and I am starting to really believe that 2"+ total liquid is very possible over the area.   You don't see a juicy system like this BEFORE the phase too often.

If you ask me it's a sign that the NAM is too far west. GFS is probably too far east as well. Ride the middle aka the Euro

So what we should take away is that the NAM should have been a bit more east/lower qpf with the correction for the 2-3C error?
