I honestly trust the NAM here more than the RGEM. I get that there is confluence, but its also a southern stream system....how the RGEM manages to cut the precip at KLWM, yet still have it warm enough for rain across most of the region is beyond me. I know this isn't a SWFE, but I still generally trust the NAM to sniff out warm layers. Now, if you want to tell me the QPF is overdone by a third on the NAM, sure...okay.
