Thomas Klosterman, 5, of Coldwater, tries for a monster splash while jumping into the pool at Coldwater. Coldwater swimming pool manager Bob Miller said the community pool has averaged more than 500 visitors each day during the last week due to the extreme heat and humidity. High temperatures today and the rest of the week are expected to stay in the upper 80s with a chance of pop-up showers nearly every day, according to local weather forecaster Dennis Howick.
