My main questions about this potential event (devil's advocate
against the potential threat):
1. Will directional shear be sufficient to produce supercells
in the South since the Low pressure center will be so far to
the north?
2. Will instability be sufficient to sustain severe weather
since there is expected to be a lot of heavy rainfall in
advance of the trough?
3. You have to think about climatology, right? This is October.

Watch the trends as the system comes across. It will answer all your questions. I think you guys will have a decent shot at something. you are a lot closer to the low than we are and they are predicting severe weather out of my WFO... Be ready
I will be watching! We will need a lot of sun tomorrow to help the atmosphere recover from the heavy rain expected tonight and early tomorrow a.m. I expect a broken line of storms to roll through here, some with rotation.
