It's a record we may break, whether we like it or not: The number of days this winter that the low has been below zero. We've seen 19 subzero lows so far, tying with the winter of 1872-73, according to the National Weather Service. The worst -- or best -- was the winter of 1884-85 when there were 25 such days. The normal for a winter is 7 days.
"Chicago is within striking distance of the all-time record for number of subzero lows in a season," the weather service states, crediting "the incredible frequency of arctic air masses this winter, combined with persistent snow cover."
