This looks great! I have loved the UI of Dark Sky (to the point of continuing to use the "Darker Sky" modified APK for Android, which is now due to die off in the next few days). So, seeing a replacement for the desktop site is wonderful. Also, I did try out the "Add to Home" instructions for mobile, and that works nicely!

I was about to comment that the multi-value graph at the top of the page was distracting and taking up space. Looking at it again, I can see a bit more use out of it, although perhaps still not my first preference. Comparing it vs the current Dark Sky site, I do prefer the existing large current temperature value as the initial visual focus.

The other thing I love about Dark Sky is the visual appearance and the resolution of the precipitation radar map on mobile, including the timing of animating the radar updates over time and the coloring of the base globe. I've tried out a bunch of other Android apps and haven't found anything that _quite_ replicates that. If you could reasonably replicate that, it'd be really neat.

Thanks for putting this together!
