Physics and weather forecasting are not similar endeavours. Nor is the relationship with fed interest rates and inflation transparent. FYI "people in politics" describes every economist. their businesss model relies on someone listening to them. Those people pay them money. And those are all "people in politics".
Weather forecasting is applied physics. The systems are big, some interactions aren't known precisely, and the boundary conditions are more complex than most physicists usually work with, but weather forecasting is definitely physics.
