These images were captured from NSSL's Warning Decision Support System running on the KTLX (Twin Lakes) radar.  All times include a "broad view", with 0.5 degree reflectivity and storm-relative radial velocity shown (earlier images may have base velocity instead).  These images are of the storm that eventually hit the south OKC metro area.

1. All units are in metric.  The Azimuth and Range to the center of the image are typically given in the lower right-hand corner of most images.
2. "8-panel" images show reflectivity and velocity at various heights through the storm (or tornado).  Height of the center of each image is given in the lower right corner.
3. "x-section" images are vertical cross sections, usually shown with a (quasi-)horizontal ref/vel image that contains the line along which the cross-section was taken.  All of these images are either cross-radial or along a radial.
4. Satellite imagery, within this timeline, is indented.
5. Look at the 8-panel images if you want to see the "raw data" without the algorithm output covering it up
