Washington, KS Tornado

April 29, 2010

We targeted north-central Kansas today, and it paid off in the form of supercells and a brief, weak tornado (pictures will be uploaded when I can get some still captures from the video). The moisture return was a little weak, but the dynamics and kinematics were in place for some severe storms, and given the degree of shear, I was anticipating that there could be a couple weaker tornadoes with the storms. We were lucky to be within a mile of the area when/when the tornado developed.

Mostly flat updraft base with a non-rotating wall cloud.

Weak tornado with debris cloud (see arrow).

Debris cloud grows a bit.

Still a healthy debris cloud.

Debris cloud becomes a little more diffuse.

Circulation weakens to "rapidly rotating wall cloud".
