About the mapping?  Well in weather systems like ours you can't change a single point value without also altering all other points.  For example, I would want to increase the point value for Broomfield to 4" from 2", but that would increase all values by 2".  A mapping software that allowed a weighted value change would be ideal... say you wanted to raise broomfield by 2" and it would blend that into the surrounding data.  That would help the broadcast media side immensely to have that kind of control over the gridded data.  So often the met just puts up the map that looks good for a few spots, but terrible for others with no ability to change it.
