The official track of the Little Rock tornado using Google Earth has been asked for quite a bit. From my understanding, it's still a work in progress as more information is entered into the database. The National Weather Service has done an incredible job thoroughly examining the track.
It's a KML file. Click on the image below and it should download a file to your computer. You will probably need a laptop or desktop to see this, but I could be wrong. It should open in Google Earth and if you don't, it's a free download. It's recommended you use a desktop or laptop to view.
Hope this helps and hope it works for you. I'll have more about the EF3 Little Rock tornado down the road here on the Arkansas Weather Blog
zoom in to view the track.
