National Weather Service upgrades heat watch to warning

Heat indexes set to climb to 110 to 115 degrees Wednesday

John Patyk, 13, tries to keep cool in front of a fan as he tends to his family's Patyk's Farm Market and Greenhouse near Richmond on July 25, 2023. With temperatures in the nineties and high humidity forecasted, cooling centers will be open throughout McHenry County.

The National Weather Service has upgraded Wednesday’s excessive heat watch for McHenry County and surrounding areas to an excessive heat warning.

Heat indexes on Wednesday are set to climb to 110 to 115 degrees, and the warning issued Tuesday notes some areas may see heat indexes reach even higher.

Todd Kluber, a meteorologist at the National Weather Service, said a cold front is coming through at some point during the day on Thursday, but “it will still be hot,” he said.

“That’s been the one factor that’s been the question,” Kluber said. “How quick does that front get in?”

We’re implementing water breaks every 30 minutes for athletes.”

Most school districts in the area are not planning on closing schools due to the heat wave, but some area school districts have made changes to their schedules.

“We’re 100% air-conditioned,” Damisch said. “They must have been clairvoyant.”

Crystal Lake District 47 announced late Monday that West and Canterbury elementary schools will be closed Wednesday and Thursday due to a lack of air conditioning in those schools.
