    The following change indicators are used when either a rapid, gradual, or temporary change is expected in some or all of the forecast meteorological conditions. TAF - Terminal Aerodrome Forecast A detailed forecast of expected weather elements at an aerodrome that significantly affects the movement of aircraft. TEMPO - Temporary fluctuation in some of the elements lasting for periods of 30 minutes or more but not longer than one hour with each instance and does not cover more than half of the total period indicated by HHHH. Typically, a rapid change of prevailing conditions to more or less a completely new set of prevailing conditions is associated with a synoptic feature passing through the terminal area cold or warm frontal passage. TAFs are bundled together and transmitted as a single document.

    A Terminal Aerodrome Forecast (TAF) is a concise statement of the expected TAFs use the same weather code found in METAR weather reports. range, thus the probability value 40 is appended to the PROB contraction. Like the METARs, the TAF will begin with the airport identifier.

    Wind Shear, Probability “PROB,” Temporary “TEMPO,” From “FM” and.
    If the location's three-letter identification does not begin with an A, H, or G, the last letter is dropped and the P is added to the beginning. This is followed by a four-digit group giving the beginning hour and ending hour of the time period during which the thunderstorms or precipitation is expected. In the second section we see that this report was taken on the 6th day of the month, at Z. Forecast visibility greater than 6 statute miles is indicated by coding P6SM.

    Gust is added only if the average wind speed is exceeded by 10KT or more of the mean windspeed for previous 10 minutes. The forecast includes the height of the wind shear followed by the wind direction and wind speed at the indicated height.

    Appears at the end of a TAF when no surface observation is available for the location at the time when the TAF is issued. Temporarily, from Z to Z Winds at 18 knots, gusting to 33 knots. Weather Phenomena.

    Welcome to the VATSIM PRC "Interpreting METARs and TAFs" Tutorial. TEMPO - Temporary changes expected; BECMG - Becoming; PROB - Probability.

    Any temporary conditions expected during a specific time period are included with that time period. The table below shows the abbreviations.

    The 24 indication applies to all time group ending times. In addition to these "octa" designators, we also have codes for certain types of clouds.

    Variable winds are encoded when it is impossible to forecast a wind direction due to winds associated with convective activity or low wind speeds. A Terminal Aerodrome Forecast TAF is a concise statement of the expected meteorological conditions at an airport during a specified period usually 24 hours.

    In addition to these "octa" designators, we also have codes for certain types of clouds. Routine TAFs are prepared and filed approximately one-half hour prior to scheduled issuance times.

      The last two letters reflect the specific station identification. Weather is a huge part of successful flight planning, I hope this tutorial has helped you to better understand a few of the published weather reports available to aviators.
