I know ALOT of people that refuse to ride in the rain, but I truly do not mind it as long as (like you said) there is no thunder/lightning and it's not freezing cold. Just remember:

Avoid white (or yellow) lines - they get really slippery when they are wet and even when riding on them straight, you can still slip

Slow down on corners - just pretend you are turning on alot of gravel and slow down.

Pay EXTRA attention to drivers - the rain may impair their vision more than normal. I've never had a problem, but I'm also very careful.

Use lights on front and back - Even when it rains and it is sunny (I love when that happens) I always ride with my front and back light (blinking). No matter what the weather, if it's raining, I'm lit up

Be extra careful if it just started raining - as we know when driving our cars, it's alwyas slicker when it firsts rains as it is moving around oils on the road. If I am going to ride in the rain, I usually wait about an hour to let the rain wash away the oil.
