Based on what I have read so far, it appears to be targeted to the energy Sector, wind prediction, extreme Wx events (tropical and Pineapple Express AR Events), while saving significant computational energy at the sacrifice of less Vertical layers than say ECMWF(IFS) which this paper compares it against. So it suggests a home computer with a single GPU could run a 18km or 30km in seconds, which could be useful to a targeted set of users looking for only certain things. I don't "think" it would be necessarily useful to chasers or Svr Storms forecasters unless the parameters and resolution were to resolve for convection specifically. I think there are some interesting implications of this approach though, but this thought is based on a quick overview of the paper and not a fundamentally deep grasp of this kind of modeling.
