Question Alternator Hot vs Cold Question?

I was wondering why my Volt Meter in my "S" shows 13.5 when cold (first thing in the morning), then when I start the car cold but leaving from work when the outside temps are higher, I get a lower reading on Volt Gauge like below 12.

Keep in mind I never checked "actual" voltage at the post. It's just an interior observation from the Drivers Seat.

Does this sound like a grounding issue? Or a symptom of one? Or is it something else?
