I am sure this does not include the radar but given that the road that wunderground has taken is more clear now, I am sure he is getting ready for the future.
Even with all of the available places to get near real-time radar data across the Internet, the wxradar.php page is still in the top 5 most visited pages on our site. Based on WU deprecating features without warning, I just want to get ahead of the inevitable and completely purge them from the site.
