// Version 2.07 - 24-Nov-2007 - support new zone forecast with different temp formats
// Version 2.08 - 25-Nov-2007 - fix zone forecast icons, new temp formats supported
// Version 2.09 - 26-Nov-2007 - add support for new temperature phrases and below zero temps

//data ends up in four different arrays:
//$forecasticons[x] x = 0 thru 9 This is the icon and text around it
//$forecasttemp[x] x= 0 thru 9 This is forecast temperature with styling
//$forecasttitles[x] x = 0 thru 12 This is the title word for the text forecast time period
//$forecasttext[x] x = 0 thru 12 This is the detail text for the text forecast time period
//
//$forecastupdate This is the time of last update
//$forecastcity This is the city name for the forecast
//$forecastoffice This is the NWS Office providing the forecast
//
//Also, in order for this to work correctly, you need the NOAA icons (or make your own...
//there are over 200!). These need to be placed in the path where the original NOAA icons
//are located. In my case, they are at: \forecast\images\
//properly (so make a folder in your web HTML root called "forecast", then make a folder in it
//called "images", and place the icons in this folder)
