  1. Every weather forecast should have the basics such as air temperature, type of weather (cloudy, rainy, sunny, etc), wind speed and direction as well as humidity. Then, depending on how much information you wish to include, you could put in dew point temperature, visibility, amount of cloud cover, amount of precipitation, Ultraviolet (UV) index and air pressure.


  2. Data collection

    Surface weather observations of atmospheric pressure, temperature, wind speed, wind direction, humidity, precipitation are made near the earth's surface by trained observers, automatic weather stations or buoys. The World Meteorological Organization acts to standardize the instrumentation, observing practices and timing of these observations worldwide. Stations either report hourly in METAR reports, or every six hours in SYNOP reports.

    Measurements of temperature, humidity and wind above the surface are found by launching radiosondes (weather balloon). Data are usually obtained from near the surface to the middle of the stratosphere, about 30,000 meters (100,000 ft). In recent years, data transmitted from commercial airplanes through the AMDAR system has also been incorporated into upper air observation, primarily in numerical models.

    Increasingly, data from weather satellites are being used because of their almost global coverage. Although their visible light images are very useful for forecasters to see development of clouds, little of this information can be used by numerical weather prediction models. The infrared (IR) data however can be used as it gives information on the temperature at the surface and cloud tops. Individual clouds can also be tracked from one time to the next to provide information on wind direction and strength at the clouds steering level. Polar orbiting satellites provide soundings of temperature and moisture throughout the depth of the atmosphere. Compared with similar data from radiosondes, the satellite data has the advantage that coverage is global, however the accuracy and resolution is not as good.

    Meteorological radar provide information on precipitation location and intensity. Additionally, if Doppler weather radar is used then wind speed and direction can be determined

  3. Take a look any forecast sight, such as the National Weather Service.   They include temperatures, rain chances in percentages and winds.
