How to take the current weather in the city and write it to a file or database?

In General,I don't know how to implement such a thing.
This is because you need to import some of the site the XML and write it to DB or file?
You know any services where you can take the weather updates?
In this format:
Clear/overcast/other Temperature Humidity Wind Pressure

Serious data, such as you want to format, do not spread. Can read the related topic in the GIS lab.
