Here are my weather icons.
I know that not every icon is perfect, but i will make them better and better.
The icons will also be included in rowancompsciguy's weather plasmoid http://kde-look.org/content/show.php/Weather+Plasmoid+Alpha?content=84251.
Icons have the sizes 16x16, 22x22, 32x32, 48x48, 64x64, 72x72, 96x96, 128x128 and scalable svg's.
I hope you like it and comment if you want.
