(Google Earth), Weather.com has been using it for about 4 months that I know of. Double click on the interactive and then it works just like Google Earth (It is GE actually) without running the program. Then click on the tab for “Weather Layers”. You can check radar or clouds or both. You can get pretty close to the exact area you live and see the clouds and radar if there is bad weather in the area. You can also adjust the transparency of the clouds. Its a pretty cool website.
