There is still a big gap of live atmosphere observations that are being fed into these models. Even if you throw money at them, you will not end up with increasingly better results since the initial state of the model will be the same. Throwing money at the model runs and the supercomputers will cease to provide positive returns at some point (and I think the Euro is probably near that point).
We need a dramatic increase in the number of observing stations as well as funding increase for the supercomputer time. I'm personally very interested in what we can do with smartphones right now; there are billions of internet-connected barometers that the Euro and the GFS do not use. Project like PressureNet[1] and Sunshine[2] are making huge strides there, and I think the future is very promising.
You're right, but throwing money at more observation stations, satellites, and balloons would work as well. The general "throw money" solution would work.
