STORM2K

For posterity's sake, thought I'd start a thread where information, video, pics, radar shots, etc. can be placed.

Kind of a "file" for future outbreaks, research, etc.

Radar Shot (US Tornadoes tweet) of HUGE debris ball in Moore, OK on 5/20/2013:

U.S. Tornadoes tweet:

@USTornadoes: "Cross section showing clear BWER on the tornado. Debris lofted thousands of feet in the air..."

Tweet from the legendary James Spann:

@span: "Debris ball on OKC terminal radar approaching Moore, OK #okwx pic.twitter.com/QEOEcvNlh7 "

In the tweets, you can almost hear them going from cautious to desperate between the wx balloon and the tornado emergency.

Yeah, it's almost the Twitter version of the Joplin EMS responders and their radio chatter a couple of years ago.

Some of the most amazing footage I've ever seen at ground level...shot on a smartphone.

Tweet and very up close and personal photo of the Moore tornado from storm chaser Ben Holcomb (@wx8ben, benholcomb.com) as the tornado ripped through town. Check the link out:

@wx8ben: "Moore, OK tornado as it crosses Sooner Rd at SE 134th street #okwx pic.twitter.com/g8uQkbaTX6."

Unreal video from the guys at http://www.tornadotitans.com .

Warning - there is some LANGUAGE - and they note that on their FB page. But it's intense as debris starts falling out of the sky.

Historical info from May 20, 2013 - Moderate Risk for Central Oklahoma.

Map from a Tornado Titans Facebook post. (http://www.tornadotitans.com) Their early morning FB thoughts were almost prophetic:

"Round #3 today folks. Populated areas in Oklahoma up into SW MO and NW AR are under the gun for tornadoes today. Think the supercells that fire W and S of the OKC metro could pose a significant risk to lives and property again today. PLEASE keep a source of weather information handy and contact your neighbors to make sure they are in the loop. Be proactive and not reactive today!"

Historical info - from Tornado Titans' Facebook post earlier in the day (check the time stamp):

(http://www.tornadotitans.com)

"Winds backing out of the SE in this corridor in C. Oklahoma will maximize tornado potential this afternoon with any discrete cells."

Another unreal video of the Moore tornado as it's tearing through neighborhoods. Not on YouTube yet, just on Facebook from a fellow named Jeff.

Can't believe how close this guy was.

http://www.facebook.com/video/embed?video_id=10200597107263068

Wow! This is unreal. 30 minutes of nearly wall-to-wall coverage of the Moore tornado on May 20, 2013 by veteran KFOR TV met Mike Morgan and helicopter pilot John Welsh.

Absolutely unreal footage as these guys covered the tornado.

"It's grinding...80 mph inflow...it's sucking us in...folks, there isn't time to delay or think, you've got to act now...move quickly, you may have seconds to take life saving action..."

IT IS INTENSE STUFF. Can't imagine how these guys keep their cool and do their job. Even as the tornado is threatening their own homes and families.
