I use this service all the time since I found out about it last year (on HN) because it gives me more information than I will ever need and still makes it easy to consume. The most unique aspect of this implementation is the historical data they provide to give you an idea of weather even when there is no forecast. This is unbelievably valuable when planning a trip to a new region of the world and I routinely use it to plot my locations and timing accordingly.

The only real problem I have with this site is the heavy dependence on flash, and a few clunky UI controls when interacting with the graph over a long period of time.

We recently added some very simple keyboard controls: the arrow keys (left-right: pan, up-down: zoom), that might alleviate that problem a little.

Yes, you need to click in the app once to give it focus before it registers the keyboard clicks. Just one of the many little gotchas with flash... (don't get me started ;)
