This assumes the wind is flowing over a frictionless surface with no protrusions. In reality trees, mountains etc cause drag below, and other atmosphere causes drag above. Drag is proportional to the cube of speed, so I really don't think a wind turbine will be able to affect wind speed much. Well, not more than reforestation would, and wind turbines don't even cause local temperature or humidity differences like a forest would.

But, I think a larger issue air is never calm. So it's going to be hard to notice at low speeds because winds are often much stronger than that and going in random directions. Still, IMO that's on the order of magnitude you would need to do things like shift a hurricane's path slightly.
