Problems With TWC Sounding This Evening

The 00Z sounding for Tucson this evening is shown above for 26 July 2010. There are several superadiabatic layers aloft and the sounding also appears to be 3 or 4 mm too dry wrt GPS precipitable water. There may be a fair amount of CAPE to support nighttime storms, but then again there might not. This example illustrates how difficult it can be to interpret soundings from the RRS sonde that have data problems.
