There are many different weather stations out there to choose from. Costco has some, Camping World, or if you want the really good, Maximum and Rainwise make ones to the National Weather service standards. BUT, they are expensive.
Davis instruments, as mentioned, and one that I have is Oregon Scientific. Both good, and more reasonably priced.
I have an Oregon Scientific one in the Monty, and I have the Maximum weather station at the stick house, but the Maximum cost me over $1500 for that one.
Just "Google" home weather stations and be prepared for lots of viewing.
I actually also have one that is very basic, with a rain gage (tube) a wind direction arrow, a temperature gage, and a whirligig that I just stick in the ground.
