Air compresor outside OK?

Hey, I picked up an 80 gal upright 5hp 2 stage air comp. since my 30 gal oil-less is the loudest useless piece of junk ever made. I really would like the extra space in the garage (and the new compressor is HUGE) so I am going to pour a cement pad behind the garage and build a small shed. It doesen't get too cold here in the Tacoma, WA area but just wanted some input on the best way to go about this. I will need to run the 240v wiring out to it and was thinking of having a switch in the garage so I don't have to go outside everytime I want to use it.

Thanks
