From now on, I'd recommend that if you see any signs he's going into shed, hold off on feeding until after he sheds. Some snakes have no problem with multi-tasking, but with others it can really mess up their shed (where it sticks- they need help- & it comes off in tiny pieces- trust me, it's not fun).
The reason is simple: digestion uses more water in their body, & so does shedding -they actually secrete some moisture between the old & new skin right before they shed to facilitate the process. So if their body is digesting, they may not have enough hydration to do both easily: some snakes may upchuck their meal (because without proper hydration they cannot digest it) while others may digest but get stuck in the shed process. Neither scenario is good.

And that's why, in the wild, most snakes instinctively don't hunt to eat when they feel a shed coming. But as pets, it's often hard to resist "room service".
No, don't raise the temperatures- actually, when snakes are in shed, you'll notice they usually gravitate to the cool part of their homes. Trust your snake to figure out where he needs to be now.
