When I said 20 chasers, that may have been a slightly low guess...

[EF-5bigj]

That's a lot of chasers in a small area with a likely rain wrapped tornado.

Rick Smith shared that thought as well...almost makes you wonder how it took so long for El Reno to happen.

Is this your mobile phone, RL ?

[Bunkertor]

No wonder that one is going tornadic, imo. Great pics by Sinnerstormchasing btw.

Wheres that pic from because I'm skeptical its from today. There has been no reports of a large tornado.

I couldn't get a tag for it because its a screen grab but there have been 1 or 2 reports of a large tornado from this main supercell today, the NWS used the strong wording "A large and extremely dangerous tornado" in the TOR warning at one point.

Brett Adair ‏@AlaStormTracker 1h - One chaser overrun by the tornado....just got the phone call. They are okay, but can't release information now. Video was rolling...

It happened again!

[EF-5bigj]

El Reno should be a good lesson on what not to do.

"can't release information now" = trying to find highest bidder for video of them almost getting themselves killed.

[RL3AO]

TDS just west of Omaha?

82 mph gust in Omaha as that line passed through.

We still got several tornadoes today, but the main deterrent to a bigger outbreak (like what was expected) appears to be weak anvil level winds. If they're too weak, the main supercell type is high precipitation and they usually congeal into a line very quickly...such as today and May 31, 2013 to name two.
