The combination of a cold Canadian-origin air mass, clear skies and light winds allowed temperatures to drop to their lowest levels so far this fall at many Chicago-area locations this Wednesday morning. Lowest airport reading was 20-degrees at Rochelle, followed closely by 21-degrees at Aurora/Sugar Grove. Burlington just across the Illinois-Wisconsin border also recorded 21-degrees. Both Midway and O’Hare, Chicago’s official site bottomed-out at 29-degrees.
