"Futurecast" could be from any model. I think most use the RPM or GRAF, but some show the HRRR too. The thing is, I don't think anybody mentions or displays the model type on air. So I can see where it leads to confusion. Also, that is one snapshot. I'll take hi res models like an ensemble. Look at trends, see if the same area is identified for heavy rain etc. The run to run of the HRRR won't always show the same area getting mauled, but I can get an idea from a multitude of runs showing the same similar geographical area getting nailed.
