With temperatures in the 90s and the heat index soaring to over 100 degrees, Thursday was one of the hottest days of the summer. That made the splash pad at Riley Park Pool an important destination for moms and kids who were looking for a little relief from the heat. The National Weather Service issued a heat advisory for the day and warned people to be careful if they had to be outside. Fortunately, relief is on the way: Highs will be in the high 70s to low 80s this weekend.
