Their 10-day weather graph is one of my favorite interfaces. There is no better way to grasp the weather, and it transformed my conception of daily weather patterns. Try it:

Don't overlook the Customize button at the top right.
I use the similar (but a bit wonkier) weather.gov graphs. I have it bookmarked on my phone, for checking the weather before I ride. After a bit you can figure it out at a glance. It also tells me sunrise and sunset times.

They have a regular 7 day forecast[1] with text, but I prefer the graph for my commute.

I feel like weather.gov is 80-90% of the way there, but having incrementally grown the ui/ux feels dated and needs a little love.
I would love to hear what people are using as alternatives. I already use Dark Sky on iOS as well, so that's one. I just want a good 10 day view :(
For example I waited 82 seconds for your link to load and another 55 seconds after clicking 10-Day, on a 40mbps connection.
