Welcome Chelle! A little late to this topic but better late than never

(I'm trying to be a more active member of the IIS society, I was slipping through the cracks!)
As for things to do when the skies are cloudy...well, most of what has already been mentioned here! Planning for observing can be just as fun, I tend to post-it note a million pages with notes and the like or write up observation reports. I have even used print screen shots of Stellarium to star hop to certain objects. Compile and list and any maps you need to find said objects and plan out your next clear night!

Sometimes I even get carried away and draw the constellations with their main brightest stars affixed with labels etc...
Or learn the Greek alphabet
Agree with Suzy about taking up another hobby, although it DOES get costly
I enjoy photography and writing as well so I'm constantly back and forward between my hobbies and sometimes it can get extremely confusing

That and re-watching Star Trek
I hope you get some clear skies soon!
