Yesterday and today I spent some time focusing on adding weather icons. The trouble with weather icons is that there are so many. Below is the start of this endeavor, and I am sure there will be many more requests for the others.

Each icon uses the 2dp line for consistency with rounded end caps.

You can download these and many other community added icons at MaterialDesignIcons.com. Also be sure to checkout the new addition to the site in Android 5.0 package; which includes Vector Drawables.

Edit: Kelvin has been fixed to not include the degree symbol.
