Basic Interpolation Query

I am a bit of an interpolation newbie so please forgive my question if it is a little on the simple side!  I am looking at precipiation over a river catchment and I have point data for mean monthly precipitation from several stations dotted fairly unevenly over the catchment.  I need to interpolate so as to give a complete layer across the catchment.  I believe the method should be kriging but my question is whether there is a way ensuring the interpolation takes account of the elevation rainge within the catchment as well, due to the link between elevation and precipiation.  I have elevation for each of the guaging stations and a DTM of the entire area.

Any ideas would be gratefully received!

Many thanks
