Realistic weather icons now available: https://gum.co/xsdx
Contains 56 large weather icons, built on a 1170x1080 pixel canvas. Includes all sorts of weather types, viewable in the preview above.
The main .PSD is also included, so you can customize and edit what you wish, as long as you don't extract, share, or re-sell any embedded items.
This package includes all future updates through version 2, and I'll most definitely take requests and implement as many as I can.
