Forecast significant weather—weather phenomena are coded in the TAF reports in the same format as the METAR. METAR codes report observed weather conditions by airfield; TAF codes report forecasted weather conditions by airfield. The general principles of weather formation as well as the effects that certain weather features have on flight, in particular weather hazards to aviation - such as thunderstorms, ice or differing degrees of visibility, are part of this area. Aviation Meteorology Week 1 Notes. [Figure 3-2]. If the notation “AUTO” is listed in the METAR/SPECI, the report came from an automated source. Forecast change group—for any significant weather change forecast to occur during the TAF time period, the expected conditions and time period are included in this group. Observed weather condition reports are often used in the creation of forecasts for the same area. This information includes the type of report, station identifier, date and time, modifier (as required), wind, visibility, runway visual range (RVR), weather phenomena, sky condition, temperature/dew point, altimeter reading, and applicable remarks. Modifier—denotes that the METAR/SPECI came from an automated source or that the report was corrected. “TEMPO” is used for temporary fluctuations of weather, expected to last less than 1 hour. Let’s get started. Wind—reported with five digits (14021KT) unless the speed is greater than 99 knots, in which case the wind is reported with six digits. These reports and forecasts enable pilots to make informed decisions regarding weather and flight safety before and during a flight. full text of the classic FAA guide.

Automated weather sources, such as the Automated Weather Observing Systems (AWOS), Automated Surface Observing Systems (ASOS), as well as other automated facilities, also play a major role in the gathering of surface observations. Scheduled 24 and 30 hour TAFs are issued four times per day, at 0000, 0600, 1200, and 1800Z. Where to get METARs and TAFs. Visibility—the prevailing visibility (¾ SM) is reported in statute miles as denoted by the letters “SM.” It is reported in both miles and fractions of miles. In any form, the surface observation provides valuable information about individual airports around the country. Weather—can be broken down into two different categories: qualifiers and weather phenomenon (+TSRA BR). For example, a 00Z TAF issued on the 9th of the month and valid for 24 hours would have a valid period of 0900/0924. They are also issued to advise pilots of embedded thunderstorms, lines of thunderstorms, or thunderstorms with heavy or greater precipitation that affect 40 percent or more of a 3,000 square mile or greater region. Only CB clouds are forecast in this portion of the TAF report as opposed to CBs and towering cumulus in the METAR. To view a weather report, go to http://www.aviationweather.gov/. Fred Remer. If the forecast is greater than six miles, it is coded as “P6SM.”. Our Vision: To be the trusted authority and leading innovator for aviation weather information. The first three digits indicate the direction the true wind is blowing from in tens of degrees. The Aviation Weather Center delivers consistent, timely and accurate weather information for the world airspace system. PROB30—a given percentage that describes the probability of thunderstorms and precipitation occurring in the coming hours. The amount of sky coverage is reported in eighths of the sky from horizon to horizon. Clouds above 12,000 feet are not detected or reported by an automated station. Test your knowledge on cloud types, weather station plots, atmospheric forces, and more. This advisory circular, AC 00-45E , explains weather service in general and the details of interpreting and using coded weather reports, forecasts, and observed and prognostic weather charts. A variety of different forecast products are produced and designed to be used in the preflight planning stage. The heights of the cloud bases are reported with a three-digit number in hundreds of feet AGL. The network is made up of government and privately contracted facilities that provide continuous up-to-date weather information. Stationed at the most active air field on the east coast and provided meteorological and oceanographic support to aircraft squadrons traveling around the world. Time is always given in UTC as denoted by the Z following the time block. A remote pilot will find these weather alerts helpful for flight planning. 6-26) 1. 09 is the day of the month for the end of the TAF, and the last two digits (12) are the ending hour (UTC) of the valid period. ICAO station identifier—the station identifier is the same as that used in a METAR. Contractions are used to describe the amount of cloud coverage and obscuring phenomena. A METAR is an observation of current surface weather reported in a standard international format.METARs are issued on a regularly scheduled basis unless significant weather changes have occurred.A special METAR (SPECI) can be issued at any time between routine METAR reports.Example: METAR KGGG 161753Z AUTO 14021G26KT 3/4SM +TSRA BR BKN008 OVC012CB 18/17 A2970 RMK PRESFR.
