20110914 - Regional radar composites are missing 20081220-20090111. Filled in national composite with NCDC web archives.
20110624 - Deleted my crontab that downloads radar composites and had to recreate it by hand. It must have happened around June 12. I found an error in it and fixed it. It should continue grabbing images every hour now instead of once a day, as it was incorrectly set up to do. Sorry for the inconvenience it caused you!
20110406 - Managed to fill in some missing radar composites from 20100928-20110402, but they have no state borders.

20110107 - Radar composites are missing from 20110103 to 20110107 due to a URL change at the originating web site.
20101107 - Radar composites should be working now. Some from Sep 2010 may still be the wrong region. I attempted to fix them where possible.
20100928 - The north_plains, cent_plains, and south_plains radar composites are still not coming in right. CoD is working on their website.
The radar composites from CoD sometimes show the wrong region and the eastern U.S. regions are missing from around 1800 UTC on Sep 10, 2010 to Sep 23, 2010.
Updated image download script. 20100308

On 20070905, we stopped getting WSI MASTER15 NOWrad radar composites. For a short time from 2007 0906-0928, radar composites were made from MASTER5 composites. Subsequent dates have images from College of DuPage weather pages.
Around 20070625, the web server locust.mmm.ucar.edu was retired. Change your bookmark to http://www.mmm.ucar.edu/imagearchive.
Select a date and press Go! A list of image categories will appear in the frame on the right. Choose a category and sub-category and the animation will begin.
If animation takes too long to load, try lowering "max frames".
