The Chicago Tribune is reporting, “After a brief spell of spring in the Chicago area, temperatures will drop 30 to 40 degrees Thursday afternoon, when a winter weather advisory goes into effect for sleet and freezing rain.
As of 8 a.m., it was 56 degrees at O’Hare International Airport, and the National Weather Service said it could reach 62 before temperatures plummet. That would break the record high for this date of 61 set in 1880.
A strong cold front will then move into the area from the west in the afternoon, and temperatures are expected to drop into the 20s over three hours, just in time for the evening rush. The winter weather advisory is in effect from 6 p.m. until midnight…”
