Looks good to me! The main layout is clear, well-designed, and I like how you provided some extra weather info beyond the requirements.
The main thing I think could be largely improved is the interface for "The Next Six Days". It's not clear that that text or any of the days are clickable. At first, I though something was missing or not working. I would do something to make them look more like buttons or links. At a minimum, I would set the cursor to pointer when any of those options are hovered over.
