Mine goes from cold up to this position, slowly over the first 5 minutes or so that the engine is running.
Once it arrives at that position it stays steady regardless of 32 degrees or 115 degrees outside. I have a 180 degree thermostat.
If I park the truck and come back 10 or 20 minutes later and start it, the gauge begins at 1/2 with the needle straight up, and within about 15 seconds goes down to the pictured reading.
