Forecasters predict Chicago will get down to its coldest temperature so far this winter, -19°C, overnight:
What arrives Thursday night and Friday morning on gusty northwest winds is but a lobe of cold air off that vast wintry reservoir of air. If there's one piece of good news which accompanies the cold blast, it's that the chill is to hit hard for a day and a half then back off, giving way to a more moderate brand of cold air this weekend. But, while its stay here is to be comparatively brief, the near -18°C low temperature predicted at O'Hare is to be accompanied by 24-32 km/h sustained winds likely to generate dangerous wind chills under 20-below---and potentially as low as 30-below in a few of colder locations north and northwest of the city.
But on this day in 1985 we experienced -33°C, the coldest temperature recorded in Chicago. If I recall correctly that was one of only two days in my four years of high school when they closed the school for weather—because they couldn't start the buses.
At least the snowstorm pounding the central U.S. will miss us.
