re: Deep South Severe Weather Thread (Enhanced)

The line of storms to the West is moving about 10 kts faster than the warned storms. We need to see it catch up and the whole thing line out.

NWS St. Louis confirmed two tornadoes so far and their preliminary damage survey showed EF2 and EF3 damage:


I've said before that we have a whole lot to learn about debris on radar. I believe radar capability has progressed much faster than our understanding of it. I would love to see these two tornadoes lead to research into debris signatures and radar presentation of Correlation Coefficient during tornadic storms during the Fall.

Thinking over the amount if debris fallout that was clear in both of those tornadoes, not just the TDS, but the fallout as what was lofted descended to the ground, I believe leaves and other vegetation could be part of the radar presentation we saw. The way it was scattered gave more of a signature than we usually see. Dry fall leaves and other dry/dead vegetation weighs less than green vegetation like we see in the Spring. It could very well be lofted higher and kept aloft longer to be distributed over a greater distance. Hopefully, last night's tornadoes lead to some good research.
