You covered it.

I would NOT attempt a drive without refilling the system. I too would use distilled water until I found and corrected the leak.

If you don’t refill, the low coolant sensor can and probably will shut you down or at lease derate the engine.

 I don't think I'll get it to leak if I'm just up to 185 or so since it stopped leaking last night once temp came down.  Or I guess hypothetically could I have lost enough coolant to be below the leak now?  Seemed like it was more temp related.  I apologize for my ignorance if that would not be a thing on being below where the leak would be.  

You're on to it being temp related....actually its temp/pressure related.  The cooling system once it cools down and or the pressure is relieved by opening the tank your leak goes away.  Once you do the above recommendations its quite possible that you won't see a leak until its back up to operating temp.
