WXSIM forecast formatting script by Saratoga-Weather.org.

The forecast is made by the software WXSIM, which is a program, that uses the weater data from Buskelundtoften and weather data from aprox. 280 wx-stations in a distance of about 1.700 kilometers from Buskelundtoften.
For calculation of the UV-values in the forecast for all the days - Dobson Units are kindly accessiable from TEMIS/ESA
I have setup the program to automatic calculate a forecast each hour, using the newest data.
The forecast will be updatet here at this site app. 20 minutes past the hour.
WXSIM creates a textfile, which a PHP scipt automatic translate into appropriate icons. The PHP script is made by my good friend Ken True, who is a former programmer at Intel. He lives in the town of Saratoga at San Francisco, California, USA.

HEAT INDEX
The Heat Index (HI) (or apparent temperature) is a measure of relative discomfort due to combined heat and high humidity. It was developed by R.G. Steadman (1979) and is based on physiological studies of evaporative skin cooling for various combinations of ambient temperature and humidity. As temperatures climb above 90 °F and humidity goes above 40 percent, conditions are ripe for heat related illnesses.
