Condensation/fog inside windshield front and back

[atlfreebird]

Just purchase a 2012 Fiesta SE 3 weeks ago. After a recent rain storm and and having the car parked all day in humid weather, I notice some inside condensation on the inside of the front windshield, the rear windshield, and a small amount on the driverside window (all of this is inside the car). The next day it was gone. Is this a defect that should have me running back to the dealership, or is it normal in hot humid wet weather (Georgia). Honestly, I've never had a brand new car before, and expect everything to be perfect. Am I overreacting? Thanks in advance for any feeback.
