Are they on the same times or different times?

You should try using the Miscellaneous->Simple difference formula.
Load in your WRF files, then select the Formulas Data Source and
the simple difference formula.Choose a display (or right click 
on the formula and select Evaluate and Save) and when prompted, 
select the two fields you want to difference from the loaded data.
If they are on different times/spatial domains, the second
grid will be resampled to the domain of the first grid.
