NUCAPS vs Observed RAOB

Today we got a special sounding at 18Z from KMAF to compare with the 19 Z NUCAPS sounding at roughly the same location. The NUCAPS sounding was able to pick up on the stable layer above 850 mb, although the NUCAPS sounding did have it a little higher. Also, after modifying the boundary layer T/Td in the NUCAPS sounding, MUCAPE values were very comparable between the two.
