Problem with a dual Skew-T plot

Howdy,

I'm trying to plot a model sounding and a raobs sounding together on a
Skew-T, and there seem to be good explanations of this at

<http://www.ncl.ucar.edu/Applications/skewt.shtml>

In particular, I've stolen most of skewt_4.ncl for my own script. I'm
having a problem in that the script ABENDS as follows:

 fatal:Variable (cape) is undefined
fatal:Execute: Error occurred at or near line 968 in file
$NCARG_ROOT/lib/ncarg/nclscripts/csm/skewt_func.ncl

fatal:Execute: Error occurred at or near line 80 in file
DualSoundingPlot.ncl

However, if I set the dataOpts@ThermoInfo from False to True, it seems to
work. Unfortunately, I don't really want this ThermoInfo on the plot. I'm
wondering if this is a bug. In the short term, I'll just figure out a way
to work around it, but wanted to bring it up.

I've made my script and the two datasets (very small test files) available
in

Thanks,

Don Morton
