ST. LOUIS — The heat reached record-setting levels Friday in the St. Louis area.
A temperature of 101 degrees was recorded just after 3 p.m. at St. Louis Lambert International Airport, setting a new city record for June 18, said National Weather Service meteorologist Brad Charboneau. The previous record was 100 on June 18, 1953.
NWS meteorologists predicted the day’s heat index — what it feels like once humidity is factored in — would reach 105 to 107 degrees in some places.
Officials warned the combination of heat and humidity can cause heat stress for those with extended exposure or those exerting themselves outdoors, so the National Weather Service issued the heat advisory covering the St. Louis metropolitan area and a large swath of the broader region.
City officials in Troy, Missouri, were urging residents to conserve water. In a Thursday evening alert, they asked that if residents must water their yards, they do so on an alternating schedule.
Officials urged people to check on neighbors and relatives most susceptible to heat stress, including the very young, the elderly and those without air conditioning.

Nationwide, increased power demand from air conditioners being turned up high to ward off the heat has stressed electric grids.
Officials in California and Texas this week called for people to reduce energy use to avoid blackouts. But a spokesman for Ameren Missouri assured residents in the St. Louis region they had no need to worry.
“We don’t anticipate any rolling blackouts,” vice president of operations and technology services Kevin Anders said. “The grid is built for this.”
Still, heat waves can cause isolated infrastructure failures, as equipment is stressed by increased usage and heat. Anders said the company is responding to any outages. Customers can visit www.ameren.com/alerts to sign up for notifications.
Along with the heat, thunderstorms were possible along and north of Interstate 70 overnight Friday. Some storms had the possibility of being severe and the potential to bring damaging winds to northeast Missouri and west-central Illinois, forecasters said.
The chance of thunderstorms will stick around for a few days. High temperatures are forecast to be 97 degrees on Saturday and Sunday, and 86 on Monday.
