The National Weather Service in Louisville has issued an Extreme Heat Warning, which is in effect for much of the area until 9 p.m. Thursday.
“We have a very strong ridge moving in that’s already overhead over Tennessee,” said NWS Louisville Meteorologist Brian Foster. “It’s only going to be building stronger throughout the week, so we’ve got a lot of hot temperatures in store. Our heat index values are going to soar well above 100 degrees across our whole area, and so we’re really trying to message people that it’s going to be hot this week and that they need to take preparations now, find ways to stay cool throughout the hottest parts of the day.”
Foster said some relief, but not much, is expected once the weekend arrives.
“Friday, Saturday, and Sunday heat index values will be around 100 or just below,” Foster said. “Highs are still going to be in the low 90s, maybe upper 80s by Sunday, but it’s still going to be some potentially dangerous heat for the middle part of this week.”
Foster said weather officials are warning residents to avoid overexertion in the heat, and take necessary steps to stay cool.
“Things like staying hydrated throughout the day, and spending as much time in air conditioning as frequently as possible,” Foster said. “If you have to work outside, make sure to wear light clothing and also light-colored clothing like sunshirts, something that would reflect the sunlight off your body to keep you a little bit cooler.”
