It was time for some cool weather. Thursday’s 70° high was not only the coolest here since the 70° two months ago on June 17, it was the first daytime reading in September which was below normal. Still, the reading marked the 110th consecutive day in Chicago with a peak reading of 70° or higher—a new record. The 110 day streak which began back on May 29 sneaks by the previous record of 109 straight days at or above 70° set between May 24 and September 9, 1959.
Thursday’s cool daytime readings followed chilly lows of 48° at west suburban Aurora and Rochelle. The country’s chilliest air occurred out West. A low of 27° produced frost in the Grand Canyon early Thursday while Flagstaff—an hour away by car—bottomed out at 30°.
Warmth returns here with southerly winds this weekend.
