Present Weather symbols
100 weather symbols Plots of station data may include one of the following symbols to represent the present weather. METARs may include more than one type of weather condition but only one icon ever gets plotted. Two additional documents show the original descriptions abridged from the World Meteorological Organization (WMO) and which symbol you will find for which METAR present weather text string. These are not necessarily official but they represent my best matching of weather conditions to the original WMO table of icons.
