7 Day Forecast
ST. LOUIS — As the calendar marked the official start of summer Thursday, forecasters were predicting high temperatures here to reach or exceed 95 degrees on each of the next five days, topping out at 102 on Tuesday.
And the heat wave follows a stretch in which temperatures hit at least 90 during eight of the previous nine days.
“The fact that it’s lasted a while is pretty dangerous for people who don’t have adequate ways to cool down,” said Matt Beitscher, a lead meteorologist with the National Weather Service office in Weldon Spring.
Friday’s high is expected to reach 96 degrees, followed by highs of 98 on Saturday, 95 on Sunday and 99 Monday.
After Tuesday’s crest, temperatures are expected drop a bit to 94 on Wednesday and 90 next Thursday.
When the humidity is factored in, Beitscher said, the next few days will feel even hotter.

That reading, known as the heat index, is expected to be in the upper 90s in the metro area on Friday and Saturday and as high as 102 on Sunday and 104 Monday. Then, by Tuesday, the heat index in parts of the area could jump to between 108 and 110.
The Weather Service office here said the best possibility of rain will be Sunday morning, Tuesday night and Wednesday.

The hot weather here is part of a heat wave that stretched from the Midwest to New England. It brought record heat to Maine, overflow crowds to Indianapolis homeless centers and led New York to open pools and beaches early.
In St. Louis, the prolonged heat is spurring the Cool Down St. Louis charity to urge people to look in on relatives and neighbors to make sure their homes are cool enough — especially elderly and disabled people.
“Physically check on them,” advised Gentry Trotter, the organization’s founder and interim executive director.
He said some people who have air conditioners don’t turn them on because they fear big spikes in their utility bills. He said people living in older brick homes are especially at risk.
Trotter’s organization works to provide air conditioners to seniors age 62 and older and disabled people who don’t have a working AC unit; such individuals should call the group at 314-241-0001.
Also, he said, anyone who needs assistance paying a utility bill to avoid being disconnected or to get reconnected can apply at cooldownstl.org. The organization covers St. Louis city and 43 counties in Missouri and Illinois.
Trotter said members of the public can make donations at any Commerce Bank location.
Meanwhile, the city of St. Louis announced that various cooling centers have opened, with varying hours of operation.
Included are most St. Louis Public Library locations; the Five-Star Senior Center, 2832 Arsenal Street; the Northside Youth and Senior Service Center, 4120 Maffitt Avenue and Bevo Senior Center, 4705 Ridgewood Avenue.
A St. Louis County cooling center is at the Loaves and Fishes Overflow Emergency Center, 2055 Concourse Drive in Maryland Heights.
