The overdrive doesn't care if it's raining or not, all it cares about is the speed. If you're driving fast enough for the overdrive to work, then you should use the overdrive, regardless of weather. If you isn't, you shouldn't, regardless of weather. Often it's sensible to lower speeds in poor weather conditions.
You should drive slowly (perhaps 10 mph less than what is posted) and carefully in the rain. Be very careful when you are starting up again after being stopped at a red light; if you take off too quickly in the rain, you can easily spin out of control.

Overdrive use depends on speed, not weather. Can you drive at overdrive speeds, use overdrive. If you can't, don't. Often it's sensible to reduce speed in poor driving conditions.

Over-Drive
An over drive should enable you to save your fuel usage. It allows you to drive at the same speed, but using less revs, therefore you will use less fuel.
