Default y+ problem?

I have a simulation that consist of two parallel heated wall and blowing air between them. Flow is turbulent and attached picture, you can see the y+ contours on one of two walls. Although y+ value should decrease along x direction as flow gets developed, there is a region that shows an increasing. ( I enclosured in the picture). For this reason I have a heat transfer coefficient distribution that decreases from start point naturally but increases at that region then decreases again after that region.

What may cause this region ? Thank you for your precious comments.
