Wow! That is a high temp.
If I'm being honest, and that is what you asked for... I would think something is up with that temp.
I say this only because you said you woke up and didn't really feel hot or warm, right? My temp this morning was 98.67 and as soon as I opened my eyes this morning I knew my temp was gonna be up because I FELT really warm, ya know?
That being said... I do still think the rest of your chart looks really excellent. Hopefully tomorrow's temp is a bit less... odd.
