Snow Totals
On the roads, the Illinois Tollway said it has deployed its full fleet of 196 plows to clear roads.
"Our crews will be working throughout this storm to keep our roads clear and safe so our customers can safely complete their travels," Illinois Tollway Executive Director Cassaundra Rouse said. "Tollway plows are using a brine solution along with road salt to help prevent ice from sticking to the pavement, melt ice more effectively at lower temperatures and better protect the environment by reducing the amount of salt needed during storms. We're asking our customers to help us protect them by reducing their speed, steering clear of other vehicles and staying alert for changing pavement conditions and weather conditions."
The conditions led the Federal Aviation Administration to issue a Ground Stop at O'Hare. The Ground Stop was lifted at around 8:45 a.m.
As of 4:30 p.m.., 588 flights have been canceled at O'Hare and 57 at Midway.

The winter weather, combined with the government shutdown and spring break travel, is leading to lengthy delays and cancellations at Chicago's airports.
Storm brings snow, gusty winds to area, impacting travel
Transportation Security Administration agents are working without pay.
Union leaders representing TSA officers voiced their frustrations at Atlanta's airport.
"Unlike other federal agencies, such as ICE and CBP, TSA employees are working without pay. Many are coping with eviction notices, vehicle repossessions, empty refrigerators and overdrawn bank accounts," said Aaron Barker, American Federation of Government Employees Local 554 president.
Security lines got long at points but have been moving relatively quickly.
"We originally were supposed to leave out last night, and then we got a last-minute cancellation. You guys are not going anywhere. So we rebooked and we're hoping and hoping that we're able to get out of here," said Crystal Cooper, whose flight to Las Vegas was canceled.
One family from Springfield, Missouri was originally supposed to be vacationing in Hawaii two days ago. That flight got canceled hours before they were set to leave.
So they pivoted plans to the Dominican Republic, booking a flight out of Kansas.
"Then, the flight in Kansas got delayed, and then it got canceled. So then we drove from Springfield, Missouri all the way to here in Chicago, and now we're trying to get from Chicago to the Dominican Republic,while there's snow on the ground without it being delayed or canceled," Gabe Weisbrod said.
They drove eight hours overnight in hopes of catching a flight out of O'Hare Monday.
"Everyone's off for work and everything so everyone already took off. So now we're just trying to get anything possible to get out," Weisbrod said.
Another group also had their flight to Miami canceled Monday morning and pushed to Tuesday.
"Tuesday at like 3 p.m. and then we wouldn't get there until 11 p.m. so over 24 hours after we supposed to get there," Macie Ripslinger said.
They waited in the agent assistance line like so many others to rebook another flight.
"They got me rebooked twice already. I'm going to Virginia for work. And I'm running late again. I guess my trip got canceled again. So this is the third time," said Oscar Schubert, whose flight to Virginia was canceled.
The city's Department of Aviation said it's monitoring the situation and encourages travelers to continue checking with their airline for updates.
"Ordered the Uber early in the morning, knew I didn't want to," said Davis Silver, whose flight to Orlando was canceled. "Right as I got here delayed four hours, so we'll see. I've got friends flying out today, too, and no one's making it out of here now."
"We can't take another cancellation. My mom has to get back home," Cooper said.
Many had to stay in hotels Sunday night.
"This is part of a college trip. There are 13 other people with me. We came from Tokyo last night, Tokyo to here. And our trip gets canceled at 9 o'clock. That's great," said Dongyu Jin, who is traveling to Fargo, North Dakota.
Jin has been trying to get back to North Dakota to resume classes after a spring break trip.
"They say there are no flights until the 21st. I have classes coming up, tests to take," Jin said.
Sarah Parrish and her husband stayed at a hotel overnight after their flight kept getting canceled.
"We are trying to get to Indianapolis. We were schedule to get there last night. We had a connecting flight here in Chicago. And our flight has canceled three times," Parrish said.
Although the travel disruptions have been a hassle, passengers say some airlines have tried to make it up.
"I've been very appreciative, with United being able to comp me a hotel and some meals," said Eulalie Sullivan, who is traveling to Seattle.
There were several crashes on Interstate 57 early Monday morning in Iroquois County due to whiteout conditions.
No injuries were reported, but southbound I-57 in the area was temporarily closed until the weather cleared up.
Those strong storms overnight also caused damage in some areas.
Heavy rain Sunday leads to south suburban flooding
In Riverdale and Dolton, trees were knocked down. At last check, more than 300 customers are without power.
Hours of intense rainfall Sunday night overwhelmed Dolton's sewer system, forcing water back into drains and into basements across several neighborhoods.
Erwin Gray says he gets anxious anytime there's bad weather in the forecast.
"Every time it rains now, if it's a really bad rain, I'm checking," Dolton resident Gray said.
Lots of rain can mean lots of water in his house.
It's happened a few times in recent years. The latest incident was Sunday evening, when the severe storm backed up the village's sewer drains.
All Gray could do was wait for the rain to stop.
"That was my game plan, just to move stuff around and wait it out. But it didn't stop. I have not had any sleep," Gray said.
Now, Gray is left with a tub clogged with soot.
They're also assessing the damage at a multi-use space near 142 and MLK.
Water seeped through the roof, taking down ceiling tiles.
Shirley Muhammad is with the South Suburban Recovery Group, which provides disaster relief to residents. She says people have been reaching out for help.
"We've also gotten calls from South Holland, Riverdale, Phoenix. So, it's a south suburban problem," Muhammad said.
For years, Dolton has dealt with critical infrastructure challenges. And spokesperson Nakita Cloud says the mayor is working on getting funding to fix the problem sooner than later.
"He's actively calling on legislators to send in funding because we're broke. So yeah, we need the help right now," Cloud said.
The mayor is expected to assess the damage done to the village, and information will be sent out to homeowners soon regarding flood assistance.
The weather is to blame for a partial house collapse on the South Side near 69th Street and South Washtenaw Avenue. City inspectors will figure out the exact cause of the collapse.
