Right now there is a multicellular line of thunderstorms moving from Western Tn into Middle Tn. At the moment it looks like it will be here in 2+ hours, with small hail and damaging winds possible. The main threat with these storms will be the active and dangerous cloud-to-ground lightning. Severe potential seems low at the moment, but if they continue to grow I do not see a severe warning being out of the question. However, something may kill these storms entirely.
This outflow boundary that is surging ahead of this line can do one of two things. On one side, it can act as a lifting mechanism, creating more thunderstorms. Or, on the other side, it can cut off and kill these current thunderstorm’s updrafts, causing it all to die. With the current speed and trajectory of the outflow boundary (also known as a gust front), I am guessing it will do the latter. I will keep monitoring things and radar and update as things happen.
