The UK's Met Office provides a number of weather-related APIs.
This is an API module, and provides only minimal functionality by itself (a block displaying today's forecast temperature).
Enable the module to find additional region and pane styles in Panels. Below is a list of those currently included. Please share and contribute your styles! :)
Panels Wrapper
Wrap your panes and regions with unlimited possibilities.
Go HTML5! Wrap your content in the newly defined tags.
