This looks like a possible tornado trying to get on the ground.

Can someone with more experience tell me what the velocity photo above is, like what the colors mean?

...THE TORNADO WARNING FOR WEST CENTRAL DUBUQUE COUNTY WILL EXPIRE AT
630 PM CDT...

The storm which prompted the warning has weakened below severe
limits, and no longer appears capable of producing a tornado.
Therefore, the warning will be allowed to expire. However, gusty
winds and heavy rain are still possible with this thunderstorm.

The colors represent wind moving radially towards (green) or away (red) from the radar. That's why intense tornado vortex signatures are characterized by intense greens/reds paired very closely together. The bolded term, "radially" is somewhat important in the definition.

If you don't know what it means, just think of the radar site as the center of a circle, and wherever I'm looking at a storm as a point within the circle, but not at the center. The radial direction is simply the direction straight from the center of the circle (the radar site) to the region of interest (in this case, the storm I'm analyzing on velocity).

So what I posted above indicates rotation with the greens and the reds close together then? Is that correct?
