For anyone using this integration, the WRAL weather center web site appears to have changed things today, so at this moment, this integration is currently not working.
EDIT: I have put in a temporary Fix for WRAL website change.
WRAL updated their website to use a new webapi with JSON response which is actually good, but it breaks this integration. In the meantime, they left their legacy URLs around so will use those in the meantime, but it requires an update to this integration which is now available.
