Is this Drought Centered on I-85?

I just checked this week’s drought monitor. No big surprises, I guess. The drought is still here. Although, is it me or does it look like this drought is centered on I-85?

Using the Drought Monitor’s statistics and Swivel, I created the graph below which shows while the percent area in the Southeast that is in an exceptional drought has dropped in recent months, the % area in the Southeast with some level of drought is relatively constant.
