Rock ’n’ roll is older, although not by much.

On May 6, 1955, a revolution that continues to this day began with little fanfare: the first daily weather forecasts made by a computer were issued.

While a single wind turbine is unlikely to confuse a radar return signal, a wind farm, particularly one 20 square miles or larger, will pose a problem. For example, the radar returns from the weather radar in Sullivan continually measures what looks to be a rain cloud to the north. This signal is always there and is the location of a wind farm.
