The heat wave will continue through the weekend. When will it start to cool off in Kentucky?
Even thought the heat advisory ends tomorrow, the heat isn't going anywhere anytime soon. Stay safe out there, Kentuckians.
Kentucky and much of the Midwest is experiencing a heat wave and we aren't going to see daily temperature highs below 90 until next week.
Here's what to know.
While Kentucky will no longer be under a heat advisory as of Wednesday night, June 25, the daily temperature high will continue to be in the 90s throughout the rest of the week.
We will see the daily high slowly start to taper off each day, but based on the current forecast it is likely we won't see a daily high in the 80s until Tuesday, according to Kyle Wilkins, a meteorologist at the National Weather Service in Louisville.
"It might slightly cool down going forward, like right now for Louisville, we have the high as 97, and then tomorrow 96, 95 on Thursday, Friday 94, into the weekend low 90s," Wilkins told the Courier-Journal Tuesday afternoon. "So it's a gradual tapering, but it's still going to be about the same give or take a couple degrees so you're not going to see a lot of relief. It looks like our first chance of real relief may come on Tuesday [July 1]."

Any showers or thunderstorms may provide some temporary relief throughout the week, as long as the skies remain cloudy for a time after.
"Being under shower will provide some immediate relief, but if that shower moves out of the way, or fizzles and the cloud cover associated with it immediately moves, you are going to be left with higher humidity there," Wilkins said.
In the meantime, Kentuckians should be careful if spending time outside. Drink lots of water, take breaks and spend more time inside with air conditioning.
"If you're outside working, pay attention. If you start to feel dizzy, exhausted, take a break. Get under a tree, go in if you can. Drink plenty of fluids," Wilkins said. "Check on elderly, more sensitive people and people that don't have air conditioning. Just check on your neighbors and families, make sure they have water. Try to take care of each other."
