When I lived in Missouri, I used Vaseline (not the lotion) on my wet skin and blotted dry. It was the only thing that kept me from cracking.
I live on the Gulf Coast, now. Only need a light lotion in the winter, it's so nice! However, the summers almost kill me!
Along with whatever emollient you find that works, have a humidifier going in your house. That will also help.
