We always dry all of our small stuff (socks, undies, etc) inside rain or shine just because it's more convenient not to have to use clothes pins on all that little stuff. Nothing ever drips on the floor unless I've hand washed it and then I hang it in the shower until it's done dripping. We also dry our larger things outside in the winter with no problem. Even if the clothes freeze they still dry through a phenomenon called sublimation. Ever notice how a thin layer of snow will disappear even if it never gets above freezing? That's sublimation. It does take a little longer, so if you don't want them out overnight hang them inside.
One tip we've learned for drying thick fitted diapers faster inside is to put a fan on them on low. It does take a little electricity, but WAY less than a dryer, and in damp or humid weather our thickest diapers would take almost 48 hours to dry without the fan.
