Chicago’s chilly temps have reached record-setting status.
With calendars still reading summer but the outdoors feeling much more like fall, the city has seen the earliest streak of temperature highs in the 50s since 1871, according to the National Weather Service.
The recent streak from Thursday through Saturday saw highs at 56, 55 and 59. The three-day chill marked only the 23rd time such a streak has occurred in the month of September.
The longest streak was six consecutive days in 1875 from Sept. 17-22.
Other years that also saw early bursts of cool temps were 2011, which had a three-day streak from Sept. 14-15 and 1923, which saw a three-day streak from Sept. 13-15.
Thursday’s 56-degree high also set a record for lowest high temperature for that day, surpassing the previous record of 61 degrees set in 1940.
The city is expected to see highs in the 60s for much of the week, with conditions returning to the 70s by the weekend.
