Sunday forecast: Dangerous heat wave continues across Chicagoland



Chicagoland will continue to be gripped by a dangerous heat wave through Sunday and Monday.

The entire area will see intense sunshine, high humidity and possible record-high temperatures in the mid- to upper 90s, with heat index values near 110 in some locations.

An Extreme Heat Warning remains in effect for all of Cook County until midnight Tuesday morning, and until 7 p.m. Monday for Kenosha County in Southeastern Wisconsin. This means dangerously hot conditions, with heat index values between 105 and 110.

For the rest of Chicagoland and Northwest Indiana, a Heat Advisory remains in effect until midnight Tuesday morning. This means peak afternoon heat index values between 100 and 105.

Will we see a record?

There’s certainly a chance for it on Sunday.

The record high for June 22 at O’Hare International Airport is 97. Saturday’s high at O’Hare reached 94, so if it gets even a little warmer on Sunday, we could see a record.

By comparison, the average high for Chicago this time of year is in the mid-80s. Temps were already going past 80 early Sunday morning.

Very sticky air

The best way to measure how uncomfortable conditions are is by looking at dew points.

With dew points in the mid- to upper 70s predicted for Sunday, it’s going to be oppressive to miserable.

Cooling centers open

This may surprise some, but when examining all weather-related fatalities, heat is No. 1, and second place is not even close.

How does heat become deadly?

Heat waves kill by overwhelming the body’s ability to regulate its internal temperature, leading to heatstroke, organ damage and cardiovascular failure. Extreme heat can also exacerbate existing health conditions like heart and lung problems, and dehydration can cause organ shut down.

If you need a place top stay safe and cool, these six community centers will be open in Chicago to serve as cooling shelters:

  • Garfield Center – 10 South Kedzie Avenue, will be open Saturday and Sunday.

Open Monday and Tuesday:

  • Englewood Center – 1140 West 79th Street.
  • King Center – 4314 South Cottage Grove.
  • North Area Center – 845 West Wilson Avenue.
  • South Chicago Center – 8650 South Commercial Avenue.
  • Trina Davila Center – 4312 West North Avenue.

Other cooling options include Chicago Police Department district stations (available 24/7), Chicago libraries, senior centers, park district facilities, city colleges and all 50 Chicago outdoor pools.

When will it cool down?

The extreme and dangerous heat looks to be in store through Monday, before it finally cools down a little on Tuesday and for the rest of the week.

However, as the dome of heat that’s currently sitting over Chicagoland moves east, the chance for showers and storms also increases, so we could be in store for stormy weather starting around Tuesday.

And while it won’t be record heat after Monday, it still looks to remain warm and humid all week, with highs still in the mid-to upper 80s.

June heat wave perspective

The level of heat this weekend is not unprecedented, but it’s comparatively rare during the month of June.

Only five other years have logged at least three consecutive days in which the high temperature reached 95 degrees or higher. The last time it happened was 37 years ago, back in the heat/drought summer of 1988.
