Before you hit the road (or get out of bed, for that matter), check out Weather+. It's not only one of the most attractive weather apps, it’s one of the most informative, too. The animated landscapes in each screen are cool, though they'd be even cooler if they were actually related to current weather conditions. Along with current temps and sun/rain conditions, Weather+ tells you the humidity, precipitation, wind speed and direction, barometric pressure, visibility, and cloud cover percentage. Plus, you get detailed five-day forecasts and a big retro clock. You can customize the layout, dim the foreground and background, and choose how frequently to refresh the weather data.
