It’s been three decades since Chicagoans have experienced a winter colder than this.
Friday is the 22nd day this winter that we've seen temperatures at zero or below, more than the past five winters combined, according to the Chicago Weather Center. Typically, only seven such readings have occurred by now.
Subzero readings and wind chills near minus 30 were reported across northeast Illinois, northwest Indiana and southeast Wisconsin this morning.
Other cold facts:
• Since Dec. 1, the average temperature has been 19 degrees, 7.3 degrees below the average.
• So far, this winter ranks as the 8th coldest dating back to 1871.
• The latest run of cold temps has been formidable. Readings have failed to even come near 32 degrees in Chicago for nearly 180 consecutive hours. And it's far from over. Temperatures here may remain below 32 well into next week.
