What is the difference between METAR and a TAF forecast?

Think of METAR as a current snapshot of weather at an airport and TAF as the future forecast for that same airport. METAR provides observed conditions right now (and it’s typically issued hourly or every 30 minutes), including wind, visibility, weather phenomena, sky condition and cloud cover, temperature, dew point, and altimeter setting. TAF, the Terminal Aerodrome Forecast, projects weather for the next 24 to 30 hours and is issued several times a day; it outlines expected wind, visibility, weather, cloud cover, and ceilings, with specific change indicators for when conditions are expected to improve or deteriorate. In short, METAR tells you what’s happening now, TAF tells you what to expect in the near future.
