I think a tepigram and a skew-t are not quite the same thing, though they serve the same purpose (analagous to the difference between a Mercator and Lambert chart).

I found a good blank tephigram on the net if anybody wants to plot the soundings.

This tephigram shows the dry adiabats as paralell straight lines, whereas the SALR is clearly temperature dependant (not fixed 1.5 C/1000ft as some texts imply) and approaches the DALR at high altitudes.
