What chart is used to look at the forecast for surface conditions?

The TAF, or Terminal Aerodrome Forecast, is specifically designed to provide forecasts for surface weather conditions at airports. It offers detailed predictions concerning significant weather phenomena over a specified time period, usually 24 or 30 hours, and it includes information about expected wind, visibility, and significant weather events that could impact surface operations. The TAF is highly relevant for pilots as it assists in assessing the atmospheric conditions that will be experienced during landing and takeoff, which are crucial times for safe flight operations.

In the context of the other options, METARs provide actual weather observations at a specific time rather than forecasts, GFA (Graphical Forecast for Aviation) presents graphical weather forecasts but often includes upper-level winds and other information in addition to surface conditions, and AIRMETs are advisory products issued for significant weather phenomena that may affect smaller aircraft but are not comprehensive weather forecasts like the TAF. Thus, for forecasting surface conditions specifically, the TAF is the appropriate chart to consult.
