I like the probability maps because they are useful in seeing trends when viewed over several runs. I use the 3 inch or more to get rid of the noise of the members showing a dusting. The reality is that there is 0 percent chance of snow before next weekend. No map of any kind will change that reality.
You may be right. But I got up at 345 to catch a train that is now an hour late because of a tree blown down on the track so I decided to look at the maps.
6z WB GFS precip maps. Still shows icy mess for North and West suburbs of DC. Still NE MD bullseye of light snow accumulation before changeover to ice there.
