Temperatures may climb above zero on Wednesday, maybe as high as 19.



The arctic air could produce a non-stop 60-hour stretch of temperatures that fail to break above 0, which would be the longest sub-zero period in the past 18 years, according to the Chicago Weather Center.



The coldest it's ever gotten in Chicago, according to the record books, in minus-27 on Jan. 20, 1985. The lowest high we've ever had is minus-11 on Dec. 24, 1983 and Jan. 18, 1994. Chicago has a chance at tying or breaking that record.



Another snowstorm is expected to hit the Midwest over the weekend, but the brunt should be to the south of us, the weather service said.



The 2013-14 season has so far registered 24.4 inches of snow, making it the snowiest of the past 13 years. The 50 hours of on and off snowfall since New Year's Eve produced the biggest accumulation of snow here since the Ground Hog's Day blizzard in 2011. Some places recorded 18 inches or more, many to the north of Chicago.



Midway Airport recorded a 12.3 inches over the three days, and O'Hare International Airport 10.9 inches.



Other totals: 18.8 inches at Gurnee and 18.2 at Mundelein; 16.3 inches at Libertyville; 16.1 inches at Elk Grove Village; 15.5 inches in Lake Zurich; 14.2 inches in Lincolnwood; 11.5 inches in Oak Park; 6.5 inches at Chesterton, Ind.; 4.6 inches at Kankakee; and 3.5 inches at Peotone.
