CHICAGO -- Thousands of people across the Chicago area are still without power following Sunday night's snow storm.
The outages come just as temperatures across the area drop, only expected to top out in the middle 20s on Tuesday.
About 20,000 ComEd customers are without power, down from a high of 340,000. North suburbs including Arlington Heights and Glenview were among the hardest hit.
ComEd brought on additional crews from other states to help restore the outages. Some crews are working 16-hour days to restore light and heat to Chicago area homes.
The power came back on Tuesday evening at Joe Runtz's block. He said his home got down to 47 degrees Monday night.
ComEd's Tim McGuire said he sees the toll that working long hours in the cold has on the company's lineman.
"They get up, they come in, don’t ask any questions and they give you 16 hours a day. Get their rest. Barely see their families and they come back out again," he said.
Runtz and his neighbors said they are thankful for ComEd for restoring their heat.
ComEd has made significant progress, but outages still remain. The company said the majority of those who still do not have power will have it restored at some point Wednesday. A few outliers may have to wait until Thursday.
