DD/HH  DDD FFF A TT H W C

DD   Valid Time Forecast Day (UTC)
HH   Valid Time Forecast Hour (UTC)
DDD  Surface Wind Direction (to a point, not from; e.g. 090 means towards the east
FFF  Wind Speed (km/hr)
A    Air Stability Code (from Lifted Index)
      LI   <= -1.5       A = 1
     -1.5  <  LI <  1.5  A = 2
      1.5  <= LI <  4.5  A = 3
      4.5  <= LI <  7.5  A = 4
      7.5  <= LI < 10.5  A = 5
     10.5  <= LI < 13.5  A = 6
     13.5  <= LI         A = 7
TT   Air Temperature Code (deg C) (temperatures greater than 50 are encoded as 50,
     temperatures less than -49 are encoded as 99, temperatures less than 0 are
     encoded by adding 50 to the absolute value of the temperature.
H    Relative Humidity Code (encoded with the 10s digit of the value where 100% = 9
     for example, 19% is 1, 56% is 5, 6% is 0
W    Significant Weather Code (Fog or BR is 4, Rain and Freezing Rain is 6,
     Mixed/Ice and Snow is 7, TRW or Svr TRW is 9, no precip is '-'.
     ***Note*** Code 9 is not evaluated in this output.
C    Total Cloud Cover is evaluated on a column directly above the model grid point
     and does not account for a horizon to horizon view.  If any of low, mid or hi cloud
     cover is evaluated as greater than 50%, cloud cover is encoded 2, otherwise
     it is encoded as 0.
