I've really noticed 4 "natural" catalyst for convection in our area. #1 is the sea breeze and it usually doesn't work for us #2 is the differential heating along the blue ridge, it may occasionally send a storm or 2 our way but they generally die in the triad #3 some weird deal in the sandhills I'm not sure if it's differential heating due to the sand or an albedo thing but storms love to fire in moore, hoke, Scotland, Cumberland counties #5 Piedmont trough this is usually our winner but so far its been biased too far west. It seems like though there is a seasonal trend and the Piedmont trough initially focuses in the central Piedmont in June and early July but as summer wears along it drifts east. If you look at today the sea breeze went off first and shot NW as an outflow, the sandhill convection went up and got enhanced by the seabreeze then the Piedmont trough got active and the sea breeze enhanced it too. Unfortunately we were again left in crap town.
