Right now in Bowling Green, it is in the upper 70s with a very muggy dewpoint of 72. A stationary front lies just to the north of Kentucky that will likely dip down into part of the state throughout the week.
Surface Observation
The high pressure system to the east is keeping us stuck in this sauna instead of getting to enjoy the pleasure of fall weather. Looking at the GFS, it looks like that system should finally be pushed out Tuesday. A very deep trough from the northwest will come through to push that high pressure system out of the way. This trough will give a big boost in rain/thunderstorm chances for Wednesday. We also have the chance to see the leftovers of Tropical Depression 14 Wednesday and Thursday. Heights will increase Tuesday so there is a good chance we will see at least some showers from that.
GFS Wind Speeds and Heights at the surface
Unfortunately looking at the dewpoint models, it doesn’t look like we’ll get a ton of relief. Sunday and Monday will both be pretty nasty on the muggy meter. Sunday and Monday both are looking at maximum dewpoints at 72. Dewpoints will drop to 71 Tuesday, but then jump back up to 72 Wednesday. Thankfully Thursday is looking to have its maximum in the upper 60s, which believe it or not will be a big improvement.

So in summary
The Good: Relief is on its way sometime between Tuesday evening and Wednesday.
The Bad: We have a high pressure system that does not want to leave.
The Ugly: The muggy meter will be extra nasty to us until Thursday.
Sunday will reach a high of 90 and a low of 68 with a slight chance for rain over night.
Monday will hit a high of 88 and a low of 69 with a slight chance for rain.
Tuesday will see a high of 87 and a low of 68 with an increased chance of rain and a slight chance for thunderstorms.
