Mostly sunny day at 11:30 and the fans aren't on yet..
The roof is hot, the inside roof planks are warming up..
But, the attic peak sensor is only showing 61.8 (outdoors is 45.5).

I looked at the ridge vent with binocs and I could see the heat wave effect.
Inside the attic, I measured the temp of the planks close up..
The lower planks were warm, the middle planks were warmer.
Higher=warmer.. Until the last plank at the peak.. 20 deg colder!
The ridge vent is sucking out the heat!
