Frequently at RSW METAR/SPECI and weather reported on the ATIS is inaccurate. This leads to poor decision making and flight planning mistakes by pilots; dispatchers and meteorologists who rely on the weather observations to be accurate and representative.[One day] a thunderstorm was reported in the METAR for several hours after it ended. A few days earlier a FC (funnel cloud) was reported in METAR by accident when none occurred.The ATC at RSW should either learn how to augment the ASOS properly or leave it in AUTO mode. Currently; the ATC augmentation of the ASOS at RSW leads to a poor and inaccurate product which has the potential to be dangerous.
A pilot reported that RSW METAR at times was inaccurate with outdated conditions or conditions which have not occurred.
