Take a few bucks out of your wallet and your options will greatly expand. For minimalists, there's Shade ($2), which boils the forecast down to a mélange of simple colors and lines in a surprisingly cogent UI.
Another personal favorite is Weather Line ($4), which offers a clean and simple interface that plots temperatures and precipitation on an interactive graph to illustrate daily, weekly and monthly trends.
Finally, I would be remiss if I didn't mention Authentic Weather ($1). Easily the most irreverent weather app on any platform, it eschews everything about forecasting and plainly tells you what's going on outside using, shall we say, rather colorful language. You could always look out a window to get the same results, but Authentic's naughty attitude is way more fun.
