The Sager Automatic Forecast System
-----------------------------------

Files needed:

    FORECAST.COM
    SAGER.DAT
    WEATHER.DAT
    WINDDIR.DAT
    WINDSPD.DAT




System Description:

  The IBM-PC Forecasting System is an automated weather forecasting
  package derived from the Sager Weather Forecaster handheld manual computer.
  Forecasts computed by the system should be fairly accurate for about
  a six to twelve hour period. However, as time goes on the forecasts
  tend to be less accurate. You may be suprised, though, how close the
  forecasts are to the TV news forecasts.

  The software was written in Turbo Pascal and should work on any IBM-PC
  compatible system. The source code is listed as 'FORECAST.PAS'.


Input Required:

  1. WIND DIRECTION:  Wind direction should be two alphanumeric characters
     that represent one of eight wind direction vectors.

                           N  = NORTH
                           NE = NORTHEAST
                           E  = EAST
                           SE = SOUTHEAST
                           S  = SOUTH
                           SW = SOUTHWEST
                           W  = WEST
                           NW = NORTHWEST


  2. BAROMETRIC PRESSURE:  The barometric pressure at sea level  in
     inches of mercury.

              29.95 = Twenty-Nine point Nine Five Inches of Mercury


  3. PRESSURE TENDENCY:  Pressure tendency is the current tendency of the
     barometric pressure.

              R  = RISING
              RR = RISING RAPIDLY
              N  = NORMAL
              F  = FALLING
              FR = FALLING RAPIDLY

     NOTE:  It is normal for the pressure to rise in the morning and fall
            in the afternoon. This cycle is repeated during a 24 hour
            period.


  4. SKY CONDITION:  Sky condition is the condition of the atmosphere. The
     possible conditions are:

               CLEAR   = CLEAR SKIES
               PCLOUDY = PARTLY CLOUDY SKIES
               MCLOUDY = MOSTLY CLOUDY SKIES
               CLOUDY  = CLOUDY SKIES
               PRECIP  = RAIN, SLEET, SNOW, ETC. (PRECIPITATION)


  NOTE:  All of this information is available hourly from the National Weather
         Service here in Atlanta on NOAA weather radio frequency 162.550 Mhz.
         It is also available by telephone at 767-1784 or 767-1785.

         Also make sure that you are in UPPER case mode when you are entering
         alphanumeric characters.
