KTBW Laps versus NUCAPS Sounding

The 18Z NUCAPS Adjusted Sounding came in drier than originally thought. But taking a closer look at the LAPS Layer PW data...the drier sounding makes sense. At a clear air retrieval point bout 15 miles off of the coast of Whitney Beach, FL showed ample moisture at low levels but much drier air at mid and upper levels. The total layer PW according to LAPS was 1.7" but the NUCAPS sounding indicated a TPW value of 1.3". Drier air was noted in WV imagery so perhaps the actual PW value is somewhere in the middle.
