Temps will effect velocity differently depending on the powder. Some a good deal.
Which and how much well... that's why you have a chronograph.
Figure it out. 
Load development aside, I try to test things in the conditions I think I'll be using them if possible/applicable. You know, if I'm trying to figure out what the drop will be for a hunting rifle that I'll be shooting in sub freezing temps, it's better that I go with February numbers than July numbers.
