CHICAGO — April 2018 was Chicago’s fourth coldest April on record and the city’s coldest April in 111 years.

The snow and chilly temperatures of the month’s first three weeks were but a faded memory Monday as temperatures at both Chicago airports reached 80 degrees, making it the warmest day in Chicago since October 9. Readings as high as the mid 80s are on the way for the opening days of May. Strong southwest winds will keep the area warm through Thursday.

April’s precipitation total was also low, especially in areas west and southwest of the city.

Relative humidity levels Monday afternoon dropped as low as 13 percent at Midway International Airport. Weather will remain dry Tuesday afternoon. A Red Flag warning has been issued for a second day.

Much-needed rain is likely by Wednesday night as thunderstorm chances rise.
