I think he meant sheer(windsheer) vs a Microburts..
You can have windsheer and not have thunderstorms overhead...
Posit that anyone in here stating they are flying into thunderstorms as part of research in a small general aviation aircraft are typing these posts from the underworld.
You don't fly through CBs, everyone knows this. Hurricane chasers can in large C130s and such, specialy built to handle the turbulance, and they pick thier way through it as best they can, with more then typical radar setups.
