The National Weather Service is predicting the heat index for Louisville to be mostly in the triple digits for the next week. While we won't experience record-breaking temperatures, this is expected to be the longest heat wave Louisville has experienced this year.National Weather Service meteorologist John Gordon says the combination of high temperatures and a high pressure system means more air quality alerts. He also notes this is the time of year when high school sports teams often start practicing. "I worry about the football players going out, the runners, people working in construction, it’s pretty unpleasant. They cannot drink enough liquid."Gordon echoes advises citizens to "wear a lot of sunscreen, drink a lot of liquids, protect the pets and animals, the elderly, and the young."The coolest day out of the next ten should be Monday, with a high of 88 degrees.
