Chicago’s recent run of late-season warmth will continue in full force as October opens.
Despite a 16-degree plunge from Saturday’s summery high of 84, Sunday’s 68 was still pleasantly mild on a spectacular fall day complemented by plenty of sunshine and low humidity.
Temperatures will quickly rebound into the middle 70s Monday and surge to July-level middle 80s on Tuesday potentially making this the warmest start to October in 37 years since the mercury peaked at 84 on October 1, 1976. The autumnal warmth should continue in slightly diminished fashion through Friday as clouds and showers throttle temperatures a bit.
The coolest weather of the season should arrive by the weekend in the wake of a cold front as gusty northwest winds are expected to drop high temperatures into the upper 50s by Sunday, a level of chill not experienced here since a 57-degree high on May 25th.
