The NAM is significantly colder than the GFS. Not sure what to think of that, but the 18Z nam was 11 degrees colder than the 18z GFS, at 84 hours. I don't put much stock into the Nam, especially at 84 hours but that may be something to watch.
It will be interesting to see how well models handle the cold air. Most globals don't handle artic air well, and tend to be slow with it. Plus it seems like there will be snow on the ground still north of us. Would a quicker arrival of the colder air, push the system further south?
Yeah... I see no reason to get excited about this one. Southwest up through central Oklahoma might get something but outside of that, I am not seeing anything. The trend of boring winters continues.
It has been the best model for me, but who ever the met is that's been commenting here, says it should be tossed so idk what to think. I want to believe it, but I need to see some support from other models.
