It was off the entire time? Why was it even out?
Even still, you need to leave it in rice for a few days for sure and at this point, I would open it up and make sure it's fully dry before you go plugging it in. Not sure if you lucked out. A phone left in a storm doesn't sound lucky at all.
I left my iPhone in a thunderstorm last night, it sat for about 12 hours overnight.
Putting it in rice to see what will happen...it was in a Otterbox commuter.
But the one that I'm maybe wondering that I have going for me is - it was dead. No power.
Possible better results since it wasn't on?
If it was turned off it means there is no possible way it has short-circuited, on the other hand twelve hours before you put it in rice might mean that there is oxidation/rust on components that can eventually cause damage.
If you're not handy yourself, hand it in for a thorough checkup/cleaning before trying to turn it on.
I just looked and it looks like the little water indicator is still silver and not red?

Well, there really aren't that many places where water can get into an iPhone... How well does the case you had on cover those openings?
It's pretty solid.

It's two parts - the first being a rubber casing around the phone, then a hard casing. The port would have been closed, and the ear jack would have been closed.
My neighbor said though when it was found it did have standing water on the screen and the case was damp on the inside.
I'd say chances are good that it will be fine - since your iPhone was rained on and not submerged.
If not, Apple will replace it for $249 or $299 (can't remember which). Good luck.
