From the snippet below which I pulled from your log file, it looks like a 
GeoTools CRS database configuration problem. At least for this particular 
dataset. Is this a WRF NMM dataset? Do you know if it is on a staggered grid? 
If so, that may be the problem (though I'm not sure exactly what it would even 
be trying to do in that case). If not, it may be that the data is on a grid for 
which GeoTools does not recognize the CRS (or the CRS authority).

Is this happening for all your datasets? Could you send me a sample dataset 
that is showing this problem?

Ethan
