I agree with GM.It would be like slightly parting your lips on a motorcycle without a face shield.Ram air will "pool" in the indent,however,since there is generous leading edge radii beyond the cut out and its still in a positive pressure gradient,the flow will remain attached around the radius without separation.It's no problem.
