What are TAFs used for?
The Terminal Area Forecast ( TAF ) is the official FAA forecast of aviation activity for U.S. airports.

What is the difference between MOS and TAF?
While TAFs provide the official forecast for 666 airports throughout the US and its territories, MOS provides weather guidance for over 2100 airports including some military air bases.

Is TAF more accurate than MOS?
Pilots should use MOS in a similar way they may use a TAF keeping in mind that TAFs are constructed by highly trained meteorologists and will ordinarily be more accurate than a MOS forecast for the same airport.
How long does TAF last?
