[Z06] foggy windshield?
I would say even though you don't feel or see the water, it is definetely there hence the foggy windows. It is a common problem with the rubber weatherstripping going bad so no cause for alarm and you can replace it if you want a complete fix. For the summer my car was not garaged (I know the horror!) I bought a nice cover and never had a problem after that, so that can be a fix as well.
There are many places where the sealant/glue used to attach the roof are not exactly "complete". Water leaks in, and goes places where you may not realize. After researching on here, I found a couple spots that were more obvious once I removed the interior. I had one spot that was not so easy to locate...
Unfortunately, the only effective way to track down your leaks is pull all the carpet out and have someone spray the car down heavily, while you look for any traces of water on the inside. The most elusive leak for me to find, was under the hardtop, just behind the doors. At that location, water drains forward and then down behind the doors somewhere. On the inside of the car, I found a very, very small area about 6-8 inches below and a little bit rearward of the upper seat belt mount. I literally could only stick one finger in there, but it was filled with water, which then overflowed and trickled back towards the trunk. Somewhere in there that was a gap in the sealant and water was leaking into the car. I used my finger and slowly filled that entire void with RTV sealant. I've been dry since. Of course, that's after sealing about 3 other leaky areas.
