Tank temperature help

[JLollino]

so I live in Chicago and it's been pretty hot and humid out here so it's been starting to worry me and khaleesi's tank is getting up to around 25% humidity but my bigger concern is that her basking spot is between 100 and 110 depending on how high she wants to go but she normally stays at the 95-100 area. I'm taking temps with a really good temperature gun so these temps are extremely accurate. But the problem I'm having is her cooler side is getting the lowest 84 degrees and this is in the opposite corner and she never goes there. The farthest over I have seen her go is temped at 85-86 degrees and I know this is too hot. I just feel like she never really seems flustered or too hot as she enjoys being in her basking spot and she will venture over to the cool side but not for long. Everything else is going great, good poop, eating well, daily baths and no lethargic behavior. How can I get her temp lower? I also have her uvb bulb on the inside of her tank which I custom installed because I've heard it's much better and the screen on top reduces up to half of the uvb. Any help would be great, I try to turn on the air in my apartment for a little bit I get nervous as in I don't want to make it too cool. Here's my setup as of now and on the vine is usually where she stays that temps at 98.

I probably wouldn't worry too much as long as the gradient is there.

I keep reminding myself that these guys are meant to live in the Australian outback. My husband has been there and he says it's "F'n hot" during the day and "OMG cold" at night. These little guys are programmed to survive in that, so I'm pretty sure your baby will do well in your tank.

At least, that's what I keep telling myself.

How cold does it get at night once the heat light is off. I wouldn't worry about the AC - turn it on. Look up the average temperatures for different cities in the outback. Most of them still get cold even during the summer.

I agree that having the gradient will allow for self regulation so she will move around as needed. I live over in Iowa and have similar temperature fluctuations. I've found that using an adjustable lamp stand for the basking light is useful for these seasonal fluctuations because you can just raise it up higher on warm days and lower it when it gets cooler.
