Here is an example for aviators given today for my airfield, Sandefjord-Torp ENTO in Norway:
METAR: ENTO 051250Z 01016KT 9999 BKN029 M08/M13 Q1001
short-TAF: ENTO 051100Z 0512/0521 36015KT 9999 SCT020
The METAR is the present weather observation. The Short-TAF is the forecast for the next 9 hours.
The METAR says: at ENTO (the airfield) the day 05 at time 12:50 zulu (same as GMT) the wind is from direction 010 at 16 knots. The visibility is over 10 km (9999 is in meter and the maximum used). There are broken (more than 50 percent of the sky) clouds at an altitude of 2,900 feet (flight level 029) the temperature is - 8 C and the dew point, -13 C (minus is written M and not a minus sign). The atmospheric pressure (QNH) is 1,001 hPa.
The TAF says: at ENTO the day 05 at time 11:00 zulu, the forcast for day 05 time 12:00z to 05 time 21:00z, wind from 360 at 15 knots, visibility more than 10 km and scattered clouds (less than 50 percent of the sky) at 2,000 ft.
Simple, isn't it? ;-) Well, it is if you are a pilot.
