If any one uses the Weather Channel XML feed for current weather and forecast, be aware that they are discontinuing that service 10/31/2011 and replacing it with a $62 monthly service.
I got the notice today as I use it in a program that I have.
So, it may be necessary to create new weather support for RR should anyone wish it.
I've done a very cursory search and I believe that the NWS has a similar feed but I'm not sure. Currently I use their radar source.
