WIND DIR   = WIND DIRECTION AT 3 HOURLY INTERVALS
WIND SPD   = WIND SPEED IN MPH AT 3 HOURLY INTERVALS
CLOUDS     = CLOUD COVER AT 3 HOURLY INTERVALS
  CL = CLEAR SKIES (0-5% CLOUD COVER)
  FW = MOSTLY CLEAR SKIES (6-25% CLOUD COVER)
  SC = PARTLY CLOUDY SKIES (26-50% CLOUD COVER)
  B1 = MOSTLY CLOUDY SKIES (51-69% CLOUD COVER)
  B2 = MOSTLY CLOUDY SKIES (70-87% CLOUD COVER)
  OV = CLOUDY SKIES (88-100% CLOUD COVER)
POP 12HR   = PROBABILITY OF PRECIPITATION FOR DAY AND NIGHT
QPF 12HR   = PRECIPITATION AMOUNT IN INCHES FOR DAY AND NIGHT

THE FOLLOWING PARAMETERS APPEAR AS NEEDED...
WIND GUST  = WIND GUST IN MPH AT 3 HOURLY INTERVALS
MAX QPF    = MAXIMUM AMOUNT OF PRECIPITATION OCCURRING AT ANY ONE LOCATION
SNOW 12HR  = SNOWFALL AMOUNT IN INCHES FOR DAY AND NIGHT
WIND CHILL = HOW IT FEELS BASED ON TEMPERATURE AND WIND EACH 3 HOURS
MIN CHILL  = LOWEST WIND CHILL OVER LAST 6 HOUR PERIOD
HEAT INDEX = HOW IT FEELS BASED ON TEMPERATURE AND RH EACH 3 HOURS
MAX HEAT   = HIGHEST HEAT INDEX OVER LAST 6 HOUR PERIOD
RAIN       = PRECIPITATION TYPE FOR EACH 3 HOUR PERIOD IS RAIN
RAIN SHWRS = PRECIPITATION TYPE FOR EACH 3 HOUR PERIOD IS RAIN SHOWERS
SPRINKLES  = PRECIPITATION TYPE FOR EACH 3 HOUR PERIOD IS SPRINKLES

  VW = VERY WINDY (31-39 MPH)
  SD = STRONG (>40 MPH)

AVG CLOUDS = AVERAGE CLOUD COVER FOR EACH 12 HOUR PERIOD

MM = MISSING DATA

IF A HURRICANE IS EXPECTED THEN THE FOLLOWING APPLIES...
0-24 HOURS BEFORE LANDFALL...THE ACTUAL WIND SPEEDS WILL BE USED.
25-60 HOURS BEFORE LANDFALL...THE CODE "HU" WILL BE USED FOR WINDS
                              AND "HG" FOR WIND GUSTS.
61-120 HOURS BEFORE LANDFALL...THE CODE "HU" WILL ONLY BE USED.
