Tushka Tornado: "Hook" and Radar Discussion


The Tushka tornado of April 14, 2011 was the most intense weather event to strike Texoma since the Lone Grove event of February 2009. The storm killed 2 people and injured 25 more, and destroyed the school along with many other buildings in Tushka.

The National Weather Service rates the twister as an EF3, which places its winds in the range of 136-165mph.
The radar image above was captured from Doppler 12’s archive file: it shows the textbook “hook” shape associated with stronger tornadoes. This tornado is just a mile or two west-southwest of Tushka at the time of this scan.
What causes the hook? Fierce winds wrapping into the center of rotation are moving horizontally and upward at the same time. The effect around the tornado is so strong that precipitation which would normally be in that area is held aloft and/or wrapped away to the north and west. This leaves a clear “hook” shape on the radar display as the beam samples the lower levels of the storm.
Will we see more tornadoes in Texoma this spring? There’s no way to know for sure, but the typical season peak comes in the period May 1-20.
Take Care,

    the multiple vortex tornadoes like this one are much harder for radar to read accurate wind speeds. Would have been best to get a ground based reading from a mobile unit. I was 1 mile south of the tornado on 69/75. The NWS reading was as accurate as you could have gotten, but the separate vortex inside my have briefly went EF-4. All I can say is it was closer to 165, than 135.

    First of all you gave very good advanced warning on the Tushka tornado. I disagree with the NWS. I believe it was an EF4. I live 2 miles from Tushka. I Saw it,felt the ground shake, and heard the sound. I never experienced anything like that. I saw the damage to the school. The winds had to be faster than 165mph.

    I wanted to add that this is one of the huge advances with channel 12 compared to the "other" option in this area. Channel 12 is the ONLY media outlet that has their own doppler radar up here. The "other" service I mentioned uses the National Weather Services radar which are located near Norman, Ok, Fort Worth, TX, and Tulsa, OK which due to the distance of those it makes some severe events such as tornadoes more difficult to identify on radar, but with the proximity of KXII 12 Doppler, it helps to provide better views, warning, and an easier understand of what is actually taking place. Thanks for your investment in proper equipment.

    Just wanted to send you and your team and big Thank You for always being there for the public during severe weather. You give us a peace during these storms because you cover the areas and let us know where the severe weather is and where it is going. Year after year KXII is ALWAYS there for us. Thank you all sincerely for keeping us aware.

    An astonishing capture of what were certainly some terrifying moments. Compliments to the KXII weather crew.

    Just to say how much we appreciate your continued coverage during weather events such as this. In your coverage area, we have many relatives and friends, Okla. & Tx., and seems a weather event such as this always affects someone we are close to. Hats off to you and your team--and to those "first responders" to disasters. My husband and I are retired fire dept. volunteers and understand what goes on when the need arises. I am a retired newspaper reporter/journalist and photographer, and understand somewhat, the positions one must deal with when covering such events. No easy task - ALL!
