In aviation weather, what does SPECI indicate in a TAF?

• A. A special observation when there is a significant change
• B. A routine forecast for no changes
• C. A weather phenomenon confirmed temporarily
• D. A revised temperature reading

Answer: (A)

SPECI signals a Special Meteorological Report. It’s issued when weather conditions change in a significant, potentially disruptive way between routine observations, so pilots and operations receive urgent, up-to-date information. In a TAF context, it means a special update was triggered because the observed conditions have shifted markedly and the forecast may need to be updated to reflect that change. This is why the option describing a special observation when there is a significant change is the best choice. It isn’t a routine forecast, it isn’t merely a temporarily confirmed weather phenomenon, and it isn’t simply a revised temperature reading.
