Northern central states are astute at fighting driving snow and subzero chill, but the early cold snap this week could hit them like a boxer's punch thrown before the opening bell.
This blast, reminiscent of last January's deep freeze, comes too early for comfort. Leaves are still on the trees, and a snow dump is coming – a foot or more in parts of Minnesota and Wisconsin.
The leaves can make the trees accumulate more snow, weighing branches down more than they would if they were bare, CNN meteorologist Tom Sater says.
More falling limbs could mean more accidents, downed lines and power outages. But there's more.
After his party's losses in the midterm elections, President Barack Obama will wade into a mass of foreign policy challenges during his trip to Asia this week.
Obama made America's pivot to Asia a centerpiece of his foreign policy architecture. But some commentators say the President, beset by crises elsewhere, has failed to put words into action.
"The Asia pivot remains more rhetoric than reality," CNN's Fareed Zakaria said. "Having promised a larger U.S. military presence in the Philippines, Singapore and Australia, there is little evidence of any of this on the ground."
Obama arrived Monday in Beijing, where the greater U.S. focus on Asia is viewed with deep suspicion.
She stumbled into the business naked, bleeding and burned.
And in desperate need of help.
This 16-year-old girl thankfully got it, and more than a month later is in good condition at a hospital and undergoing rehab, Charles City County, Virginia, sheriff's Capt. Jayson Crawley said.
And the man accused of doing this to her? Authorities say they think he is now in custody in Maryland, where he was caught coming out of a vehicle with a woman he'd allegedly abducted Sunday night in Philadelphia.
The suspect in both cases is Delvin Barnes, 37.
Chilling video shows how ISIS brainwashes children with propaganda films.
Jana was a 19-year-old in her final year of high school, with dreams of becoming a doctor. Then, ISIS came to her village last August, and her world collapsed.
She described to me in chilling detail, how the jihadis first demanded that members of her Yazidi religious minority convert to Islam. Then they stripped villagers of their jewelry, money and cellphones. They separated the men from the women.
A United Nations report explained what happened next. ISIS "gathered all the males older than 10 years of age at the local school, took them outside the village by pick-up trucks, and shot them."
Among those believed dead were Jana's father and eldest brother.
A different fate lay in store for the women.
About 200 Syrian rebels entered the besieged city of Kobani at dawn Wednesday with weapons that included mortars and heavy machine guns, a Syrian rebel commander said.
Col. Abdul Jabar Okaidi spoke to CNN by phone from inside Kobani, a Syrian border city.
Okaidi said the rebels are using weapons from the Free Syrian Army supplies, but did not disclose which brigades offered the weapons or assisted.
This is the first group to enter, and more fighters will come in if required, he said.
"Today, 200 is enough," he said. "But we can send more today if needed."
Nearly 7 in 10 Americans are angry at the direction the country is headed and 53% of Americans disapprove of President Barack Obama's job performance, two troubling signs for Democrats one week before the midterm elections, a new CNN/ORC International Poll shows.
Democrats are battling to try and save the Senate majority, while hoping to prevent more losses in the House, which the GOP controls by a 234 to 201 margin.
In the Senate, Republicans need a net gain of six seats, and several state polls in the past month of contested races show that Democrats are in danger of losing control of the majority, and thus Congress. Currently, Democrats control the Senate by a 55-45 margin with two of those seats held by independents that align themselves politically with Democrats.
Boko Haram gunmen kidnapped at least 30 boys and girls from a village in northeast Nigeria during the weekend.
The abductions are the latest in a string of recent kidnappings by Boko Haram that dims hope for the anticipated release of 219 schoolgirls held by the group since April following a controversial ceasefire declared by Nigerian authorities.
Heavily armed Boko Haram gunmen invaded the town of Mafa, in Borno state, on Friday through Saturday and seized 30 boys and girls, local leaders said.
The news of the kidnappings was slow to emerge due to lack of telecom service in the region, where most telecom towers have been destroyed in Boko Haram's five-year insurgency against Nigeria's government.
A doctor who recently returned from Guinea has tested positive for Ebola - the first case of the deadly virus in New York City.
Here is a timeline of Craig Spencer's movements since he got back from the West African nation:
When did he return from Guinea?
Spencer came back to the United States last week after treating Ebola patients in Guinea, where he worked for Doctors Without Borders.
He completed his work in Guinea on October 12 and left the country two days later via Brussels.
He arrived at John F. Kennedy International Airport on October 17, but he exhibited no symptoms of the virus until Thursday morning, said Dr. Mary Travis Bassett, New York City's health commissioner.
The physician, who works at Columbia Presbyterian Hospital, was checking his temperature twice a day. He has not seen any patients since his return.
Did he have any symptoms?
The 33-year-old did not have any symptoms after his return, but developed a fever, nausea, pain and fatigue Thursday morning. He began feeling sluggish a couple of days ago, and his fever spiked to 100.3 degrees Thursday, authorities said.
How many people has he been in contact with?
Spencer was in contact with four people after he started exhibiting symptoms, authorities said. Ebola isn't contagious until someone has symptoms.
Three people - his fiancée and two friends - are being placed on quarantine and monitored, health officials said. The fourth person is a car service driver who had no direct contact with him and is not considered at risk.
Spencer also went for a three-mile jog and visited a bowling alley in Brooklyn prior to feeling symptomatic, according to Bassett.
The bowling alley closed Thursday as a precaution, but it said in a statement that health officials have determined there are no risks to customers.
He also traveled on three subway lines. "At the time that the doctor was on the subway he did not have fever ... he was not symptomatic," Bassett said.

First a soldier guarding a hallowed war memorial was gunned down in Canada's capital. Then shots erupted in the halls of the country's Parliament minutes later.
The two shootings in Ottawa Wednesday left lawmakers barricaded inside offices and parts of the city on lockdown for hours as police searched for suspects.
Ottawa Police lifted the lockdown Wednesday night and said there was no longer a danger to the public.
But many questions remain about the shootings: Who was the gunman? Why did he open fire? And was he acting alone?
"It appears there was just one shooter, and that shooter is dead," Ottawa Mayor Jim Watson told CNN's Anderson Cooper. "But it has been a traumatic experience, obviously, for not only our city but the country."
Investigators haven't provided any possible motives for the shooting. Canadian Prime Minister Stephen Harper didn't provide details about the investigation in a televised address to the nation Wednesday night.
"In the days to come, we will learn more about the terrorist and any accomplices he may have had, but this week's events are a grim reminder that Canada is not immune to the types of terrorist attacks we have seen elsewhere in the world," Harper said. "Let there be no misunderstanding: We will not be intimidated. Canada will never be intimidated."
It is unclear whether additional suspects were tied to the shootings or whether additional arrests have been made. The Royal Canadian Mounted Police said more information would be provided in a press conference Thursday.
As authorities continued to investigate, details began to emerge about the man they suspect was behind the shooting.
Michael Zehaf-Bibeau was identified by Canadian officials to their American counterparts as the suspected gunman, multiple U.S. officials told CNN.
Bibeau, who was born in 1982, was a convert to Islam and had a history of drug use before he converted, two sources said.
His passport had been confiscated by Canadian authorities when they learned he planned to go fight overseas, a U.S. law enforcement official told CNN's Susan Candiotti. The official said it was not clear when that happened.
Canadian broadcaster CBC reported that Bibeau had a record of drug arrests going back 10 years.
