I’m here at Tybee Island with some friends in a severe thunderstorm that we just experienced! It was something else! We were inside and I watched it closely!

In good news the heaviest rain (1.5-2.5”) set up directly over falls lake AGAIN and the lake registered its biggest one day jump since the free fall started

Yep the run ahead outflow killed us.

So technical question: I know that outflow from one cell can kill another.  But how does any cell manage to last any length of time and sometimes move 100+ miles without always chocking on its own outflow since that spreads out in every direction?

Had a good thumping with the storms here today. Picked up 1.49" rain so far today. See if we can anything else this evening.

The short answer is shear. In simple terms, CAPE is a measure of the fuel in the atmosphere for storms and wind shear is what allows storms to organize and not choke themselves off so quickly (should be at least 25 knots but preferably more). Today there was not much shear present so it makes more of a pulse storm scenario where they pop up and die quickly.
