The models may or may not be accurate but they have nothing to do with predicting the weather. There isn't any weather underground... It's all slow diffusion and buoyancy.

A better starting place might be asking where the model inputs come from.

Doesn't "diffusion and buoyancy" technically describe the weather, too?

Diffusion and buoyancy are indeed both things about the weather, but the nonlinearity of the navier-stokes equation stems from the ability of convection to transport momentum. Fluids moving through rocks can't go fast enough for that to happen.
