NUCAPS Shows Increasing Instability Across RAH CWA

The mid-day NUCAPS (top below) profile shows an unstable atmosphere across the RAH CWA with MUCAPE around 2500 j/kg. This is especially helpful as the latest LAPS data to come in is over 3 hours old.

The upper levels in the NUCAPS sounding appears to show a much drier profile than the observed sounding from GSO this morning (bottom above). In the upper levels, this seems reasonable, especially after looking at the latest upper level LAP layer PW (below). A substantial dry layer is clearly moving into the region, so this upper level drying is believable. I'm not sold on the much drier lower levels of the NUCAPS sounding because; a) NUCAPS does poorly in the lower levels, b) the LAP layer PW shows moistening in the lower levels, and c) were it not for a few very moist obs around 550mb in the observed sounding, the lower portions of the two soundings would look very similar. Perhaps the moist layer around 550mb in the observed sounding contained bad data?
