How cool is it tonight?
It's so cold that one village is postponing its mosquito spraying.
The village of Woodridge sent a notice to residents saying it is putting off its skeeter spraying until Thursday.
"The treatment was rescheduled because the cold weather and mild winds will make mosquitoes less active, resulting in a less effective treatment," its emailed notice said.
National Weather Service data shows it did actually hit 70 today at O'Hare International Airport, despite a forecast high of 67. But a breeze with gusts as high as 22 mph may have given you a chill. It was only 57 degrees Tuesday morning.
The normal high for this time of year is 85.
It's expected to be even chillier tonight, with temperatures in low 50s. Will you even kick your heat on?
The suburbs will be like much of the Midwest with cooler temperatures all week resembling fall.
"If we get anywhere near or below 52 degrees tonight, officially out of O'Hare, that would be a record low for this date," ABC 7 meteorologist Jerry Taft said.
The record low on this day was 52 degrees in 1975. The record high was 98 in 1976. The record low for Wednesday is 49 in 1945.
