your night temperatures are fine for most orchids. If you want to put them out go ahead.
My shade-house is unprotected and the plants stay outside year round down into the low 30s.
I do not consider humidity as important as other people. A dry environment can damage flowers, but we are horribly dry here in Florida all winter, and it does not seem to hurt the plants.
Avoid direct air blowing on the plants, especially flowers,
