What’s the hottest Fourth of July ever in Kane County? What was the coldest? The wettest?
The National Weather Service Chicago keeps track of those sorts of things, with 144 years of data to choose from.
The hottest Independence Day temperature ever in these parts is 102 degrees, and that record was hit twice, in 1911 and 2012. The coldest temperature was 50 degrees in 1972, and the wettest was in 1995, when we got 1.72 inches of rain.
Just about half the time, we get rain on July 4, and we break the 100-degree barrier about 17 percent of the time.
What’s in store for this year? The National Weather Service isn’t making a prediction as of Tuesday, June 28, but the Weather Channel is showing 86 degrees and sunny.
The following statistics comprises 144 years of data. Data collection began at the University of Chicago, then at Midway, and currently at O’Hare which is now the official station for Chicago.
