As you know, I keep a close eye on severe weather all across the south because I have family and friends in TN, TX, AL, MS, etc.... Who am I kidding, I watch severe weather across the country.
Yesterday, I was watching some wicked looking storms in Alabama. One storm in particular looked to be putting down some severe hail as indicated by radar. Radar showed what we a call a "Three Body Scatter Spike" on storm south of Marion, AL. A three body scatter spike is the little green line that is seen to the left of the storm below. A TBSS is a unique "flag" that we have large hail. I invite you to read this link to see how this anomaly occurs. More or less, when the radar beam hits the hail, it reflects to the ground... then back to the hail... then back to the radar. Since the signal takes longer to return to the radar, it "thinks" the rain is farther from the radar site. This produces the little line of false reflectivity away from the radar site. Make sense?
This assumption of severe hail was confirmed this morning when I saw the video below. When this radar image was taken, a chaser had punched right into this storm! Take a ride with him into this wicked storm for about 10 minutes. It gets pretty intense. I would not have wanted to be in that storm!
Have a great day,
