Chicago’s record-breaking heat wave continued Monday with a sixth day in a row of temperatures in the 90s.

High temperatures in area have hit the low- to mid-90s from Wednesday through Monday, according to the National Weather Service. Monday’s temperature reached a high of 92 degrees.

The predicted high for Tuesday is 89 degrees, near the record of 90 degrees set in 1998.

Sharply cooler weather is expected Wednesday, when the predicted high is 71 degrees.

Sunday’s temperature reached 93, breaking the previous record high of 91 for the day set more than a century ago in 1891.

Monday marked the sixth day in a row of high temperatures at or above 92 degrees, according to the Weather Service. That broke the record of 90 set in 1993.

There has never been a heat wave of this duration and magnitude this late in the season in Chicago, according to the weather service.

The previous latest streak of five days in a row of temperatures of 92 or higher was Sept. 15–19, 1955.

Saturday’s high temperature of 95 degrees broke the record of 91, and tied for the hottest day of the year. That meant a second record,  for the latest in the year that the hottest temperature of the year was recorded in Chicago, according to the weather service.

Relief will finally come Tuesday night when a cold front arrives and brings a chance of showers and thunderstorms.
