Neither will make much of an impact on you at those ranges.
Both can vary dramatically based on time of year and elevation. If you are on the plains it's going to tend to be very dry, under 20%. I the mountains probably around 40%
If you picked an average temp of about 40 Deg it probably wouldn't be too far off unless most of your hunting is going to be up high where it tends to be considerably colder.
