May 12, 2016: NUCAPS sounding

The NUCAPS sounding used today from MetOp IASI satellite turned out a bit more unstable than expected when modified with a SFC T=78F and SFC Dewpt=68F. The SBCAPE was 2681 J/kg which was a little on the high side compared to the RAP and LAP data.  I think the problem today is the midlevel lapse rates are much more steeper compared to the 12Z KBNA sounding (6.8C/km).  This is the sounding below.
