Summer scorcher: Highs in 90s on Monday, Tuesday

Updated: September 27, 2013 6:26AM



The week will start out a scorcher and then maybe — maybe — ease up by Labor Day weekend, according to the National Weather Service.

We got a taste of the heat Sunday, with a high of 89 at O’Hare Airport.

On Monday — when about 400,000 Chicago Public School students start classes — the high will hit the low 90s, and ditto for Tuesday, which will be hot but won’t break a 1973 record of 97 degrees. The heat is sliding toward Chicago from the southwestern states.

Moisture in the air will make both days feel more miserable, with Tuesday’s heat index potentially hovering around 100, according to the weather service.

CPS spokeswoman Becky Carroll said a majority of schools have air conditioning or partial air conditioning, and 800 fans will be available Monday. She said principals try to keep staff and students as comfortable as possible on hot days by drawing shades or moving to cooler classrooms.

If there are any clouds Monday night, weather at sunrise Tuesday weather will start out even hotter and build from there.

“A few locations could flirt with record highs as we get into Tuesday,” said National Weather Service meteorologist David Beacher.

Wednesday will be cooler, with a high in the upper 80s, according to the weather service. But the mercury is expected to be on the rise again.

Despite a heater of a week, August has had some cool patches in its first and second weeks, so overall, the average temperatures have been pretty normal, Beacher said.

People should start drinking lots of water now, he said.

“They need to prepare for it and need to prepare today,” Beacher said.

In addition to drinking plenty of water, experts suggest wearing loose-fitting clothes and scheduling activities for early morning or after sunset.

The rising heat didn’t put the brakes on Sunday’s annual triathlon.

A little wind made for a “head breeze” for bikers, event spokesman Scott Hutmacher said.

And the Chicago Fire Department provided a 30-foot wide “rainmaker” to sprinkle water on the estimated 7,000 athletes racing Sunday in the 31st annual Life Time Chicago triathlon.

But the temperature in Lake Michigan was about 72 degrees Sunday morning — or “incredibly comfortable,” for the swimming portion of the triathlon, Hutmacher said, adding, “It is not too hot, not too cold.”

The nonprofessional athletes — or “average Joes” swam, biked and ran from 6 a.m. to 2 p.m., with 51 registered professional athletes starting at 11:15 a.m., he said.
