The temperature in Chicago hasn't gone above freezing for 12 days, and got down to -20°C only last night. So right now, at -2°C, and with the sun out, it feels positively tropical.
Unfortunately, the forecast doesn't show us actually getting above-freezing temperatures as far out as it goes. Medium-term forecasts also show below-normal temperatures all the way out through mid-March. And in the latest bit of good news, the Great Lakes are almost 86% covered in ice, close to the record of 94.7% set in 1979. For perspective, a year ago the lakes got up 93% coverage and the last ice didn't completely melt until June 12th.
So, we could be in for another chilly spring and cool summer, followed by (one hopes) a mild autumn, just like last year.
And because warmer temperatures to the west of us seem to have caused this pattern to emerge both last year and this year, it could become a permanent feature of north-eastern North America's climate.
