Hi Randy-

Right now, the IDV needs a temperature and dewpoint variable and only knows how 
to compute dewpoint from Temp and RH.  In the WRFout grids, you have 
Temperature and mixing ratio.  We'll have to add something to calculate the 
dewpoint from mixing ratio.  

For WRF grids that have had WRFPost run on them and converted to pressure 
levels, the Sounding parameters will show up in the 3D grid->Derived fields.   
There is a section of the Workshop materials that covers this:

under the accessing and displaying grids section.
