Condensation
I believe condensation is mostly a concern when going from a relatively cooler environment to a warmer, humid environment. Like out of an AC'd shop into a balmy 85 degree day with 80% RH. Water will condense quickly. Going from a 70 degree 45% humidity environment to a 50 degree 40% humidity environment shouldn't be a problem.
FWIW, I shot the parts on Wednesday, 24 Oct. It was 54 degrees, Don't know the RH. Stuck just fine. I should have a completed wing in less than a week.
