Monthly Discussion Thread - Month of October, 2019
Snow steadily fell in communities north and west of Chicago most of Thursday, and a heavy band of snow that moved into downtown shortly after noon dumped snow into the early evening, making it the second-heaviest October snowfall since 1989.
The 3.4 inches of snow that fell at O’Hare International Airport, the city’s official recording station, shattered the daily record for Oct. 31 of 0.1 inches set in 2014, the National Weather Service tweeted about 6:30 p.m. Rockford Airport recorded 4 inches of snow through 4 p.m.
And if the rare late-October snowfall wasn’t enough of a Halloween trick, the day had also been marked by strong winds and 8- to 12-foot waves along the Lake Michigan shoreline in Cook County.
The overnight temperature is expected to get so low it could approach a record for cold set 140 years ago, forecasters said.
Amid a winter weather advisory, unprecedented accumulation in the city meant it was already the snowiest Halloween in Chicago’s history, Jake Petr, a meteorologist, said of the 12-hour snowfall totals released at 1 p.m.
The highest total came from a few miles outside Rockford, where 5.3 inches of snow fell in the previous 12 hours. In the Crystal Lake area, a far northwest suburb in McHenry County, an unofficial recording of 5 inches was taken by a weather spotter, he said.
The National Weather Service in Chicago said areas to the west, such as Ottawa and Joliet, could see as much as 7 inches of snow Thursday, said Mark Ratzer, a meteorologist.
Before this year, it had snowed on Oct. 31 just six times, according to the weather service.
And if Chicago tallies just 5 more inches of overall precipitation at any point in the next couple of months, 2019 will become the wettest year recorded since the weather service started keeping track in 1871, meteorologist Gino Izzi wrote on social media Thursday morning, before additional precipitation cut into the amount needed by Dec. 31 to break the record.
The adverse conditions throughout northern Illinois already prompted some communities, including Winnetka, Vernon Hills and several McHenry County locales such as Marengo, Johnsburg and Oakwood Hills, to call off trick-or-treating for Thursday, opting to reschedule.
Chicago does not have set hours for trick-or-treating; however, temperatures are expected to drop into the 20s after the storm system moves through, Petr said.
“It’s going to be really cold behind this system, really cold air will sweep through. We’ll have lows in the 20s Thursday night into Friday, and that should be kind of like our first hard freeze for the area,” Petr said.
Scott Lincoln, a senior hydrologist with the weather service, explained that the lowest temperature for Oct. 31 was 23 degrees set in 1873, but because it’s often coldest in Chicago just before sunrise, that record was not broken. Once the temperature drops behind the storm system, it should be in the 20s late Thursday, but the lowest temperature should come early Friday. If it drops to 24 degrees, as expected, it will be close to — but not break — the record for coldest low temperature on Nov. 1: 21 degrees, set in 1879, he said.
“It’s possible it could get kind of close to that,” Lincoln said. “As of right now, though, we are not forecasting that we’ll break it.”
