Where:
TEMP = Air Temperature (F; at 5 feet)                                        
DEWP = Dewpoint Temperature (F; at 5 feet)                                   
WETB = Wetbulb Temperature (F; at 5 feet)                                    
WNDS = Wind Speed (MPH; 2-minute average on the hour measured at 33 feet)    
WNDD = Wind Direction (Blowing from this direction; same as wind speed)      
CLDC = Cloud Cover (on the hour)                                             
       CLR = Clear skies [< 5% Cloud Cover]
       FEW = Few clouds [5-25% Cloud Cover]
       SCT = Scattered clouds [25-50% Cloud Cover]
       BKN = Broken clouds [50-87% Cloud Cover]
       OVC = Overcast clouds [87-100% Cloud Cover]
INV  = Inversion Temperature (F) at 50-150ft above ground                    
DEWF = Dew/Frost (D=dew; F=Frost; Blank is dry)                              
POP6 = Probability of Precip (% Ending 6 Hour Period)                        
Q1   = Quantitative Precip (Hourly / Hundreths of Inch)                      

These are site specific forecasts, typically for locations with limited
obstructions to wind. Users are encouraged to become familiar with potential
climate differences between this location and their local growing areas.
Significant differences can occur within small distances due to varying
topography, prevailing wind direction, location to bodies of water,
cold air drainage, and other physical characteristics including the
current synoptic weather pattern.
