[GEMPAK #DWM-347008]: invalid grd file

SFCNTR will allow for the contouring of a single field.  Using OAGRID and 
OABSFC should produce a grid from objectively analyzed point data specified in 
the parameter list.  In short, either method should work.

You need to run the script in steps to confirm that the grid file is first 
created and then that objective analysis is performed correctly, using GDINFO 
to confirm that the grid is created and then filled.
