weather_temp_

Sadly there is no documentation for this plugin.

#!/usr/bin/env python3
"""
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.
