This was the 12z Del Rio sounding.

This sounding is a modified NUCAPS near Del Rio. While the lower level structure was a bit different than the actual sounding, the observed sounding was taken several hours earlier before boundary layer modification. This was an unmodified NUCAPS sounding from the same region. Boundary layer moisture is not captured nearly as realistically as the prior modified example. Overall, trust in the modified NUCAPS sounding data has increased dramatically after some exposure to it. I would say many forecasters need more experience learning about the soundings through simulations to trust the data more.
