Visibility may sink to zero at times, but is expected to hover around a quarter mile, according to the National Weather Service.
Our clocks won’t be the only things springing forward this weekend. After setting a new record for cold overnight, temperatures will gradually return to normal for this time of year over the weekend, ahead of even milder conditions in the middle of next week.
It’s been meteorological spring for nearly four days, though you’d never guess from the weather. Chicago area residents will have to suffer through a couple more days of frigid weather before a gradual spring thaw begins this weekend.
It might not seem like the ideal time of year for a tornado drill, but that’s exactly what state and local officials have planned for 10 a.m. Tuesday across Illinois.
After one of the coldest months in Chicago history, March has gotten off to a relatively warmer start that might put a little spring into commuters’ step to start the work week.
This month already was the third snowiest February on record in Chicago, and March will get an early jump on the snow, with a winter storm blanketing the area in up to 6 inches of snow on Sunday, March 1.
After the snowstorm ended, temperatures dropped nearly 20 degrees in 12 hours. As of shortly before 3 p.m. Thursday, it was 18 degrees at O’Hare. By 3 a.m. Friday, the temperature had edged to zero. As of 6 a.m., it was 1 below.
Snow-covered roads made for a very slick commute across the Chicago area Thursday morning, after 2 to 8 inches of snow fell in Chicagoland overnight. Lake-effect snow was still falling in some neighborhoods late Thursday morning.
Chicago area residents will continue riding a seesaw of temperatures over the next few days, with painfully cold conditions Monday, a brief return of milder conditions on Tuesday, and then another bitter blast later in the week.
After breaking two records for extreme cold on Thursday, the double digit temperatures expected by Friday afternoon should seem downright mild by comparison.
Around 6:20 a.m., the temperature at O’Hare National Airport dropped to 8 below zero, breaking the previous Feb. 19 record of 7 below, set in 1936, according to the National Weather Service.
Brutal, bone-chilling cold was seizing the Chicago area on Wednesday, and the city won’t see any release from the icy grip of this arctic blast for more than two days.
A mass of arctic air will send temperatures plunging into the single digits during the day Wednesday and Thursday, and below zero at night both days. Thursday’s high will be only about 5 degrees, which would break a record set in 1936, when the high temperature was 9 degrees on Feb. 19.
Roads have been tough to negotiate, as wind has blown hard at times, and lake effect snow has been piling up.
Snow, frigid temperatures and 45-mph winds could make for a grisly Thursday morning in parts of northwest Indiana, the National Weather Service warned.
The temperature will continue to drop through the day Wednesday, falling into the mid-20s by the afternoon, according to the National Weather Service. That’s warm compared to Thursday, when the high is only expected to reach into the single digits and low teens.
A cold weekend is in store for Chicago, with temperatures and wind chills expected to approach the lowest recorded so far this year.
Not only was this weekend’s blizzard the 5th largest snowstorm in the city’s history, it also made the past week the 8th snowiest week on record for Chicago.
As if more than a foot-and-a-half of snow over the weekend wasn’t enough, more snow was on the way for the south suburbs, parts of the South Side, and northwestern Indiana from Wednesday morning through Wednesday afternoon.
Here are the total snow fall amounts measured by National Weather Service observers for the snowstorm that lasted from Saturday night until Monday morning.
