That didn't take long. Strong couplet one frame, almost gone the next. I guess the definition of a spin-up, and an example of why the tornado probability is lower than the other severe modes.

I think the best tornado chances as far as anything more than a spin up in the line of storms will be anything slightly ahead or on the southern edge of the cluster when it crosses into MS and later AL. There is a lot of daytime heating and nothing to impede the energy here right now.

About to get real ugly in Ruston. Seems to be a spot where tornados spin up

How do you look for debris on RadarScope?

Using Correlation Coefficient. You look for an area of lower return. But, it has to correlate with the location of the circulation on Velocity. You can't just find a low value in a storm and assume it is debris. It has to be in the same spot as the rotation couplet.

Those of you who want to better understand radar and how to use it should check out the podcast Chaser Chat with Jeff Frame and Gabriel Harber. Specifically, listen to the December 3, 2020 episode on Radar. Jeff goes into detail on the different modes of radar and how to interpret what you see. It has a primary focus on RadarScope. It would be an hour well spent if you are interested.

This is perfect for me as someone who enjoys following on RS app (and OT weather threads) but only have a casual understanding of the different radars. Thanks!

Good deal. There is plenty of good info in other episodes. Some of it is more advanced, but start with the basics of radar, hodos/soundings, and models, and you will have a really good grasp of most severe weather setups.

Dr. Jeff Frame is legit. He's a good follow on Twitter, too. You'd like that poscast.

If you want to get into the weeds, listen to the three parter on Failure Modes.

I’m on the way to Farmerville coming from downsville right now and I can barely see anything. Leaves and limbs falling everywhere. This is getting pretty scary
