Ah, Chicago, your weather really builds character.
Yesterday our official temperature got up to 27°C; today's forecast is 29°C. So it might surprise you that Sunday's low was -1°C, a record fro April 29th.
Or maybe it won't surprise you. Especially given the other records we set in April:
The Chicago area saw a record 16 days in which temperatures were 32 degrees or lower in April, said Kevin Donofrio, a meteorologist for the National Weather Service. The previous record was set in 1874 and 1873 for 15 days freezing or below-freezing temperatures. The average monthly temperature is about 49 degrees, according to the weather service.
In addition, this month may go down as the fourth-coldest April on record for the Chicago area in terms of temperature averages, Donofrio said. The cold start to spring postponed Cubs games and prompted the CTA to keep its “L” platform heat lamps on as commuters slogged through a chilly April.
Snow and cold in Canada was to blame for the lower-than-normal temperatures in Chicago in recent weeks, Donofrio said.
In April, the Chicago area saw six days with accumulating snow and three days with flurries, Donofrio said. The snowfall wasn’t uncommon, though the area did set a record on April 9 for the 2 inches of snow accumulation.
Yes, blame Canada. But really, right now Canada—really just Nunavut and northern Quebec—is the only place in the northern hemisphere with significantly below-normal temperatures. The planet as a whole is 0.4°C above normal, and hasn't been below normal in years. (This has remained true even when the normals are adjusted at 10-year intervals.)
But hey, it's May. I'll take a few spring days before we have to turn the A/C on again.
