Below, I posted about a downburst I captured using Doppler wind velocity radar yesterday. You'll see a comment asking about what a tornado looks like.
Below is the Chapman tornado from Tuesday night in the velocity data.
ADDITION: My friend and storm chaser Lanny Dean provided this photo of the tornado at the time these radar images were captured. Like so many, it was wrapped in rain and didn't look like a tornado. That is why it is absolutely vital to follow the warnings, not your eyes.
