tornado_wind.copyriteWhile inside the Goshen County, WY tornado on June 5, 2009, TornadoVideos.net recorded an astounding 155 MPH wind gust with the roof-mounted R.M. Young marine model wind monitor! TVN Instrumentation Specialist and TwisterData developer Dave Demko says, "[TVN] recorded a peak one-second average horizontal wind velocity of 155.2 MPH (approximately 3 meters above ground level) at 22:25:59 UTC (2009-06-05 22:25:50 UTC correcting for datalogger clock drift) after the crew stopped and lowered the vehicle!  Keep in mind, given the performance limitations of the wind monitor instrument in highly turbulent flow, that this observation almost certainly does not represent the highest wind velocity actually encountered by the SRV while the tornado's core flow region traversed the vehicle. The highest three-second rolling average wind speed (official WMO/NWS definition of a "wind gust") was 150.2 MPH -- WOW!!!  These speeds are squarely in the middle of the EF-3 range (136-165 MPH).

Click on TVN's Latest Chase Video (above) to view this AMAZING tornado intercept!

Strong tornadoes and extremely large hail are possible again today in Kansas, Nebraska, Iowa and Missouri as strong directional and speed shear combines with high instability over the region. Yesterday's storms were suppressed by a strong cap, but the models are indicating that the cap will break over the moderate risk area this afternoon, which could result in a dangerous weather situation! Numerous chasers will be in the area so be sure to follow along on the LIVE VIDEO tab at top left!

I think that should be used as edvidence as it was rural with nothing to damage. reeds dominator definately took a beating but held up. i think u have to add that to what wurmans radars caught im sure it was higer than a EF1. Good job to u guys

The whole situation was perfect for gathering data, and I think we're about to witness a tremendous amount of new knowledge regarding everything involving tornadoes.
Not just tornadogenesis, but all the little minute details that may have been missed before while so many things are happening and observers couldn't detect w/the naked eye or conventional radar.
An enormous amount of data was collected from all sides of this tornado and will take quite a while to colate, but boy, oh boy are there going to be some delerious storm-data-nerds involved in the process!!

Well, on the EF scale you were in an EF-3 if i'm reading the scale and 3 second wind speed average, and you wern't too far off from an EF-4 (since it starts at a 3-second average wind of 167 mph). Did it feel like it wanted to roll at all?

Reed said that it did feel like it was going to roll... fortunately this wasn't a more slowly-moving, larger tornado. I'm not thinking they would have driven into it if it had been, though. ;)

Thats some pretty neat readings you guys gathered, even though I think you guys are nuts for getting that close(just wish to hell I could).

Is there a way to get sound with the video streaming?

TIV must be very jealous of TVN at this time, maybe they will loan the Imax camera to Reed.

that was great that the wind instrument was able to get those wind gusts like that with such precision.that tornado sure did look wild and it mustve been awesome seeing that tornado.so far this afternoon the severe weather been firing up in eastern co.i heard several reports on cnn using the vipir hd radar and titan hd radar showing the supercells firing up with possible tornadoes.

WOW that is some crazy video! I think ya'll should ask the TIV team to borrow the IMAX camera. LOL

Stay safe out there guys!!

Hey Reed,

Call up a film school and get a guy to rent an IMAX camera...pump out a 20 min short of one of your intercepts...lol Casey would turn blue I swear!!

Go work all...sounds like data from multiple sources will lead to a very valuable intercept.... awesome.
