Another Weather App? Really?

As if there weren't enough of these kicking around here, right?

Working to design something everyday and had a thought while looking at Yahoo! Weather on my phone. Beautiful app, but there's just so much information in a long list format; it feels unnecessary. I'm starting from the opposite end, trying to answer two questions:

1: How much of this can you get on one screen without listing things?
2: How much do you really need?

I do plan on taking this one further, just for shits and giggles.
