I've never seen a CAP reading above 100C. I doubt if you would see one that warm. Technically though, a cap is not a proper cap without CAPE, because you need positive buoyancy for the warm air to "cap" convection as such. Its just an inversion if the temperature line stays to the right of the TAPP line throughout the atmosphere.

Michael Beazley @MBZLY · Details
@TxStormChasers yeah, CAP is broken, and storm forms.. moves along its path and runs into stronger CAP what happens?

Texas Storm Chasers @TxStormChasers Close
@MBZLY The storm will weaken and eventually dissipate. Depending on the strength of the cap, this can happen slowly or in a matter of mins.
