WILL BE GENERATED FROM THE 0000 AND 1200 UNIVERSAL COORDINATED 
TIME /UTC/ MODEL RUNS. GUIDANCE WILL BE AVAILABLE FOR THE 
FOLLOWING ELEMENTS WITH OTHERS TO BE ADDED AT A LATER DATE:

  DAYTIME MAXIMUM AND NIGHTTIME MINIMUM TEMPERATURE
  2-METER SPOT TEMPERATURE
  2-METER SPOT DEWPOINT TEMPERATURE
  RELATIVE HUMIDITY
  WIND SPEED
  WIND DIRECTION
  PROBABILITY OF PRECIPITATION /6 AND 12 HOUR/
  PROBABILITY OF THUNDERSTORMS /3...6 AND 12 HOUR/
