I get your point.
I think you're wrong...and you should get over it frankly.
I don't see fast flow as being prohibitive of a moderate 4-8" or 6-10" type of "payload" from an attenuating system in the face of confluence, abutting arctic air.
A prevalent model bias, in addition to not being aggressive enough with mid level warming to the east of the mid level lows, is to be too heavy with QPF.
I never bother to fact check him....guy is the human incarnate of GOOGLE. Whenever I am debating someone, and he takes the other side, I just immediately defer, tip the cap to the other party and about face-walk away.
I have no issue with that and am not implying a worse outcome...I just mean that some future runs may go nuts, and have S CT salivating, only to trend back or just be wrong.
This is a pretty easy forecast...these are usually straight forward. Thermals will waffle, but just default to a climo forcast.
Forecast 10"+ anywhere at your own peril.
