Here is an example station plot:
This is decoded as follows:
77 = Temperature
72 = Dewpoint
1016 = Pressure in millibars
2308 = Time of observation in UTC
= Wind velocity (in this case, from the south at 10 knots.)
= Cloud cover (in this case, mostly cloudy).
= Weather (in this case, a light rain shower).
Listing of cloud symbols:
Empty Circle = Clear (CLR) Circle with single vertical line = Partly Cloudy or Scattered (SCT) Circle with double vertical line = Mostly Cloudy or Broken (BKN) Circle completely filled = Cloudy or Overcast (OVC) Circle with an 'X' in the middle = Obscured ( X )
Circle = Calm or missing Half barb = 5 knots Each Full barb = 10 knots Each flag = 50 knots
1 = Tornado [not used] 14 = Moderate/Heavy rain shower 27 = Light Freezing Drizzle
2 = Thunderstorm 15 = Light rain shower 28 = Light Drizzle
3 = Thunderstorm with rain 16 = Light rain 29 = Moderate Drizzle
4 = Thunderstorm with snow 17 = Moderate rain 30 = Heavy Drizzle
5 = Thunderstorm with freezing rain 18 = Heavy rain 31 = Light sleet shower
6 = Thunderstorm with hail or sleet 19 = Light snow shower 32 = Moderate/Heavy sleet shower
7 = Heavy Thunderstorm 20 = Moderate/Heavy snow shower 33 = Ice Crystals
8 = Thunderstorm with heavy rain 21 = Light snow 34 = Fog or Mist
9 = Thunderstorm with heavy snow 22 = Moderate snow 35 = Drifting snow [not used]
10 = Thunderstorm with heavy frzg rain 23 = Heavy snow 36 = Blowing sand/dust
11 = Thunderstorm with heavy sleet/hail 24 = Light Sleet 37 = Mix of rain and snow
12 = Moderate/Heavy freezing rain 25 = Moderate/Heavy Sleet 38 = Thunder without precipitation
13 = Light freezing rain 26 = Moderate/Heavy freezing drizzle 39 = Smoke
