LOL. You would go for a low resolution model over a high one? All joking aside, it isn't that good. I'd use the HRRR and WRF products as well as the RGEM and NAM in combo. I'm putting more weight on the HRRR this go because I don't get snow and also it did better than the NAM with its precip last storm.
Cut at least 1/3rd of the precipitation off the NAM in a situation (amplified situation) like this, but use the temperature profiles.
