Decide on a common projection, I would go with something like AEA or LCC for 
the state of NW, then project your temp data into that location. You can cut 
out the temp data by

1. convert NM outline into raster
2. rename raster to MASK
3. make a copy of the projected temp data
4. the new copy with be clipped by the raster MASK
