Forecast Font is a lovely web-font for using any weather-related icons on our web pages as fonts. The font is pretty awesome as it consists of items that are multi-layered and this provides a huge margin for customization.
It was created to enable you to have more control over the look and feel of the icons, rather than only having a single colour or style. Flat, single-colour icons might be what your after and thats cool but with Forecast font you have all the flexibility to colour, style or even animate various parts of the icons. Create something a little different from the norm. Even better they are fully scalable for use on all devices, no need to create cumbersome image sprites or use multiple images to create your weather icons.
