Indystorm Posted March 19, 2018 Share Posted March 19, 2018 I am assuming that the atmosphere is capped south of the present storms in northern Alabama and might unzip later as the LLJ increases and more forcing occurs. Link to comment Share on other sites More sharing options...
nrgjeff Posted March 19, 2018 Share Posted March 19, 2018 Agree the Alabama cluster (responsible for the Russellville tornado) is blocking the LLJ into the Tenn/Bama Border cell. It is like blocking out in basketball. Really it is. Maybe it can get ahead and come into Chattanooga. Actually, maybe I should be careful what I wish for after dark.

pbrussell Posted March 19, 2018 Share Posted March 19, 2018 Just now, Calderon said: TDS near Lester, headed directly at Ardmore and the I-65 welcome center for Alabama. I’m still a bit unsure. There’s been a lot of radar crap associated with these storms and that apparent debris sig doesn’t match up entirely with the area of rotation. Regardless, all the signs point toward there being a tornado with that storm at some point Link to comment Share on other sites More sharing options...

nrgjeff Posted March 19, 2018 Share Posted March 19, 2018 Yep, the front cell of the cluster is dominant. Farther north cell in Tennessee also now appears to have enough space with which to work. Improvement after a hiccup is not unusual when the LLJ gets going close to dark, especially in Dixie. Could be a wild evening indeed. EDIT for below: One of the only things good about Dixie is fewer chasers. Still the terrain is one reason I sat out this one so close to home.
