Employing electromagnetically induced transparency for spectroscopy of an atomic vapor, we observe the velocity-, quantum state- and magnetic field-dependent transition frequencies between the ground and Rydberg excited states. For atoms moving at velocities around $400\,m/s$, the principal quantum number $n=100$ of the valence electron, and a magnetic field of $B=100\,G$, we measure a motional Stark shift of $\sim10\,MHz$. Our experimental results are supported by numerical calculations based on a diagonalization of the effective Hamiltonian governing the valence electron of $^87$Rb in the presence of crossed electric and magnetic fields.
