Weather reports from Chicago and the suburbs.

A winter weather advisory in Cook and DuPage counties ended at noon.
As of 9 a.m. Sunday 6,900 customers remained without power, according to ComEd officials.
The advisory covers Cook, Will, DuPage, Kendall, Kane, Grundy, DeKalb and Ogle counties from noon Thursday until 6 a.m. Friday.
The heavy fog and showers were causing hazardous driving conditions for the morning commute, the National Weather Service said.
A band of “particularly intense snow” swept into the area around 4:30 p.m., falling at an inch or two an hour and whipped by wind gusts as high as 40 mph, according to the National Weather Service.
A winter storm warning has been issued from 3 a.m. until 9 p.m. Thursday for southern Cook County as well as Grundy, Kankakee, Kendall, La Salle, Livingston and Will counties in Illinois and Lake and Porter counties in Indiana.
Cook County was under a winter weather advisory until 6 p.m. The National Weather Service said accumulations of 1 to 4 inches was possible, especially in the northwestern part of the county.
Some areas downstate could get more than a foot from the first wave of the storm. The National Weather Service said a second wave on Thursday may not be as severe as first forecast, with snowfall the heaviest south of Interstate 55.
Wednesday’s big snowstorm kept many folks at home, but not the Black family.
State officials estimated it could be the worst snow storm to hit the state since 2011, the blizzard that left hundreds of motorists stalled on Lake Shore Drive. Or it could be a standard Illinois snowstorm. Forecasters’ models have varied widely. “We are working off a range, so it’s possible that we get 6 inches of snow, it’s possible we get 16 inches of snow,” said Scott Swinford of the state Emergency Management Agency.
State law requires the budget address to be given this year on the first Wednesday in February, and a spokesperson said Gov. J.B. Pritzker will do so. But because of potential hazardous winter travel, the Senate would convene at noon on Tuesday, but the remainder of the week’s House and Senate sessions would be canceled.
The National Weather Service estimates at least 6 inches of snow will fall in the Chicago area, 8-10 inches to the south and in Indiana. Some models show as much as 20 inches, though the weather service tweeted caution.
A winter storm warning was in effect for north and central Cook County until 2 p.m.
The temperature at O’Hare International Airport hit minus 5 overnight but a balmy 30 degrees is expected for Thursday.
A wind chill advisory is in effect from 8 p.m. Tuesday to noon Wednesday in northern Illinois.
A light but steady snow made driving hazardous and forced the cancellation of more than a hundred flights at O’Hare and Midway airports.
A winter weather advisory in effect from Saturday night through 9 a.m. Sunday also forecasts a sharp drop in temperatures and wind-chill readings in the single digits.
The best way to keep your lips moist in winter is to moisturize frequently with healing ointments like Vaseline or Aquaphor, one expert recommends. Chapsticks are better in warmer weather.
Wednesday also marks the earliest date that temperatures at O’Hare reached 90 degrees since 2011, according to the National Weather Service.
The National Weather Service said it was the weakest level of tornadoes and hit the west suburb briefly around 4:45 p.m.
The last 80-degree day in Chicago was over six months ago, on Oct. 9.
It only seems like everyone is heading somewhere warm.
Temperatures were expected to continue dropping Monday, which could have “the coldest night of this most recent cold snap,” said Brett Borchardt, a meteorologist with the National Weather Service.
The official reading at O’Hare International Airport hit minus-1 at 8 a.m. Friday, according to the National Weather Service. Saturday, the weather service expects freezing rain to create hazardous driving conditions in the greater Chicago area.
The advisory is in effect until 6 p.m. for Cook, DuPage, Will, Kane, Lake and McHenry counties in Illinois, and Lake and Porter counties in Indiana.
With winter weather delaying flights and COVID-19 spurring staff shortages, many travelers returning to the city Sunday or early Monday waited hours just to get their luggage.
Regardless of age, people with a medical condition should find somebody else to clear the driveway or possibly to opt for a snow blower, one doctor says.
