I found an external hard drive I forgot I had buried at the back of my closet the other day, plugged it in, and lo and behold, it had my archived weather data folder from 2011 including my GR Level 3 screencaps on 4/27. Don't believe I've ever shared them here. It speaks to how monumental this outbreak was that even a random severe weather nerd living safely 700 miles from the impacted area remembers what he was doing that day 12 years later.
During that time I was an associate degree student for TV & Video Production at Milwaukee Area Technical College and the late April/early May period was very busy as it was crunch time for our end-of-year projects. I'd spent most of that day holed up in the student editing lab with limited ability to check the Internet for non-project-related topics. I knew there was a high risk out for parts of the South with some pretty volatile conditions expected, but I never dreamed that something rivaling or in some metrics exceeding the Super Outbreak of '74 was even possible in my lifetime, let alone that day.
I got home and fired up my computer right around the time the Tuscaloosa tornado was about to move into town, but I didn't know it until I launched GR Level 3, navigated to KBMX and my jaw promptly hit the floor. I'd never seen such a well-defined hook echo with debris ball like that outside of articles about 5/3/99, nor a velocity couplet like that since Greensburg, so I knew immediately that something catastrophic and historic was underway...and that was before I even knew about Smithville, Philadelphia, Hackleburg, Cullman and everything else that had already happened.
KHTX went down due to communications failure after I was able to save just two volume scans from it, but note that one of them shows an astonishing
forty-one tornado warnings in effect (that was before GR Level 3 differentiated between tornado warning, tornado warning with confirmation, and tornado emergency)!
