Google announced in the Google Web Search Help forums and also on Google+ that you can search for weather on your tablet or mobile device and Google will provide slicker weather information.

The Search Team is excited to announce that a weather visualization is available on tablets, just like it is on mobile phones. When you type [weather] into Google on your tablet, you'll see the current weather and you can scroll through the hourly and ten-day forecast. You can also toggle the Precipitation and Wind buttons to check out the percent chance of precipitation and wind direction/speed, respectively.
