Total PW looks good from the operational version (minus the blacked out data, of course). It is a little blotchy on the merged TPW (left). A similar comparison below of the AllSky TPW and Operational product.
CAPE is a different story.
AllSky calculations are mostly in a clear airmass, as you can tell by the operational product not being blacked out. Peak values on the right are in the 1700-1800 J/kg range, whereas points on the left peak at 2600-2800.
