It looked like I was able to create a "My Map" online with the Weather Channel and/or Accuweather.com as a "layer". I was able to add the Weather Channel as a "layer" on the phone's NAV map, but it returned an error stating there was a problem with the site coding or something.

I just thought it would be cool to be in NAV mode and have cloud cover update real time as you driving through, or into a storm. Would be even more useful if you were trying to slip in a training ride, and needed to know where the storm is in relation to your route, for those marginal days.

 

My Weather Mobile or My Mobile Weather, not sure what the correct name is, but the icon is a circle with a wavy line separating 2 halves, one side orange, the other white, has a nice radar view with optional satellite image. It may have blue dot for GPS marker, and I believe it actually uses Google Maps. I'm not sure if it tracks you while moving though, but the cloud cover seemed "real time".
