This is a 20 minute video for some weather junkies around here that may appreciate the forecasting leading up to the April 27, 2011 super outbreak of tornadoes in the deep South.

This was compiled by the Alabama weather blog in Birmingham, AL.


20 minutes of weather forcasting clips (April 19- April 26, 2011) leading up to 4/27/11 super tornado outbreak
quote:

This video includes excerpts from ABC 33/40 Birmingham Chief Meteorologist James Spann and Meteorologist Brian Peters Weather Xtreme Videos which were produced in the week leading up to the historic and tragic April 27, 2011 tornado outbreak in Alabama. The video begins with an excerpt from April 19th and takes us all the way through April 26. These are weather forecasting model discussions, not necessarily the forecast that was published officially on those days. This video was made to focus on discussions about the 27th, both at long range and as the event became imminent. I have excluded most other parts of the original discussions so that the viewer can focus on information related to April 27th.



this next video is the Nexrad of April 27 over MS and AL, highlighting all of the tornadoes.

Unbelievable numbers of tornado touchdowns that day. It's a generational type day, so we know we will get another one as bad or worse in the near future.

Love Talbots channel, was actually watching the hour and a half el Reno video earlier this week.

Everybody wanted to go South.

That day and the subsequent weeks living in Tuscaloosa is something that will stick with me for the rest of my life.

Thanks for sharing, watched the full 20 minutes. Man what a fricked up week and day that was. One I will never forget.

That event was very well forecast, and the warnings issued that day were very timely, yet we still lost 252 people in Alabama that day. Very sad.

True, but seriously, when the storms are that bad, what would most really do? The ol "center room, lowest floor" advice probably didn't work for many average built homes. I know if a major tornado had cut through our house like the many that occurred that day, I'm not so sure I'd still be here today. My home is on a slab, I have no safe room or shelter.
Look below at the destructive path from the Tuscaloosa tornado. One house had a safe room built and it was just about the only thing standing for as far as the eye could see. And this tornado has only been rated as a high EF4. If there is an EF5 coming your way, you had better just find a way to get out.

This one is really interesting. The El-Reno tornado was 2+ miles wide when it crossed highway 81, nearly twice as large as it was just a few minutes prior to the west of that location. A lot of people would have been killed if that tornado had materialized 10-12 miles east in the more densely populated OKC suburbs along I-40.

I actually read a bit about the El Reno tornado after it happened because some of the fatalities were experienced, educated researchers with a lot of experience documenting storms. They weren't locals with pickup trucks and cameras.

The size of that storm is what really astounds me. At some points, the intense damage path was nearly as wide as LSU's main campus (to put it into perspective).

I was in the OKC area few years ago and drove on Highway 81 south of El Reno. It's a wide, paved north/south highway with good sight lines and very few trees. I can see why so many photographers were staged right there. The Weather Channel's Suburban was rolled right there as they tried to escape south on that highway.

The people that were impacted in Reuter Rd. were in compact cars - one group of chasers were in a Chevrolet Cruze with a lot of awkward weather instruments mounted on the roof and a Toyota sub-compact car. I drove that gravel/washboard road (with open ditches on either side) in a brand new SUV and couldn't safely drive over 35 mph on a sunny day. I honestly couldn't imagine moving at half that speed with heavy cross wind and low visibility in a lighter car. That was a terrible escape route.

For tornados that powerful (Joplin, El Reno, Tuscaloosa, Xenia, Fairdale), I'm not sure that being in a home in the direct path without a basement or safe room is any safer than taking your chances escaping via car.

I agree, there were people that day who did the right things, sought the best shelter they could, and still died. But I think a lot of people also did not take action when warnings were issued. Now, part of the issue with warnings that day were that so many people did not have power when things began that afternoon due to the storms that morning. That certainly made it harder for people to get warnings.

But yes, I agree, there are situations when you have large, violent tornadoes where even seeking shelter might not be good enough (if you don’t have a basement/storm room). I don’t know if it is true, but I’ve heard that there were people killed in Hackleburg, AL (hit by an EF-5 that day) that were in some type of storm pit/underground shelter.

Brand new poster here. I think a lot of you will appreciate this series of videos on this subject. I was in North AL area at the time and lived very close to most of the destruction. I hope these links work.

Edited to say that all three are youtube links to the NWS Huntsville documentary on the lead up, forecasting, and surveying of the outbreak.

Excellent first post. Maybe top 5 in the history of the OT, porn bombs not withstanding.

It is all about the time and location of the post. A Saturday morning on a non-forecast weather thread. I figured this was a relatively safe thread with little chance of bashing or verbal abuse.
