munin US NOAA weather plugin (http://tgftp.nws.noaa.gov)
Draws temperature/dew point in C.
Copy/link file as 'weather_temp_CODE', like: weather_temp_LOWW for Austria, Vienna.
Get the code by going to http://tgftp.nws.noaa.gov, selecting your
location, and copying the code from the address bar of your browser; should
be something like CODE.html.
Linux users might need to adjust the shebang.
