CHICAGO (CBS) — An overnight winter storm is expected to drop several inches of snow on most of the region Sunday night into Monday morning.

A Winter Storm Warning is in effect for northern counties, including Lake and McHenry, until 6 p.m. Monday.

According to the National Weather Service, snowfall is expected from around midnight until 6 a.m. Monday morning with periods of 1 to 1.5 inches of snow per hour, especially over far northern Illinois. Blowing snow will likely further reduce visibility.

Snow totals are expected to reach 8 inches near the Wisconsin line, 3 to 6 inches near O’Hare and 1 to 3 inches in southern areas.

 On Monday, the temperature is expected to reach a high of 34 degrees and by Wednesday the temperature will drop to minus 10 degrees.

 CBS 2 meteorologist Robb Ellis says on Tuesday and Wednesday, the wind chill could drop to minus 35 to minus 55 degrees.

As of 12:15 a.m.,

The average delay time at both airports is less than 15 minutes.

City officials said they are deploying warming buses to assist homeless residents, adding shelter beds and making King Community Center’s warming center open 24 hours a day.

CPS said classes will be in session Monday. All transportation and Safe Passage services will be deployed as usual. </s> The Northeast is bracing for an intense winter storm right after parts of California have seen almost a foot of rain this week. Two storm systems have headed east.

(NEW YORK) — The Northeast is bracing for an intense winter storm right after parts of California have seen almost a foot of rain this week.

As two storm systems have headed east, with one over the Rockies overnight, more than a foot of snow has fallen in Utah and about a foot has been seen in Colorado.

The first of the two storms is moving through the Northeast Friday morning, with slick roads likely from Washington, D.C., to Boston. Snow accumulations Friday morning along the Interstate 95 corridor are fairly light — just 1 to 2 inches.

As the second storm moves toward the Plains and Midwest, heavy snow is likely in the Dakotas, Iowa, Wisconsin and parts of Illinois.

Heavy snow should be moving into Chicago, the southern Great Lakes and other parts of the Midwest later Friday night. Winter storm warnings have been issued.

Saturday afternoon and evening, this second storm is moving into the Ohio Valley with heavy snow for western New York and Pennsylvania.

South of areas receiving snow, heavy rain and thunderstorms are expected.

On Saturday night, a quick hit of heavy snow in Philadelphia and New York and many coastal areas is expected, before some of that precipitation turns to sleet and freezing rain.

New York City could see 2 to 3 inches of snow and 1 to 2 inches of sleet, with Philly receiving a bit less of both. Washington will mostly see rain, while Boston will see more snow, maybe more than half a foot.

Upstate New York, central Pennsylvania and much of New England may see more than 2 feet of snow.

Behind the storm, an Arctic blast is forecast to spill into the central and eastern U.S., delivering the coldest air of the season and brutally cold wind chills Monday morning. </s> A winter storm inched its way toward New England Saturday after leaving slick roads and runways in the Midwest.

The National Weather Service issued winter storm warnings for the weekend from the Dakotas across the Great Lakes states and into New England. It warned that conditions in the Northeast "could approach blizzard criteria."

Ice was also a possibility in some areas in the path of the storm, which was forecast to dump up to 2 feet of snow.

In Nebraska, where freezing drizzle was falling Friday afternoon, authorities closed Omaha's Eppley Airfield after a Southwest Airlines plane slid off an ice-slicked runway. In Iowa, the Department of Transportation warned that visibility was less than a half mile in many locations due to snow and wind.

And in South Dakota, where snow was starting to pile up, authorities warned drivers to give plows extra room.

The storm was expected to bring between up to 10 inches of snow to the Midwest before walloping the Northeast on Sunday. The National Weather Service in Albany, New York, said snow could fall at a rate of 1 to 3 inches an hour, creating "difficult to impossible travel conditions" in areas.

In New York City, the worst of the storm is expected from Saturday afternoon through Sunday afternoon, with snow accumulations of 3-6 inches followed by rain that could turn to ice as temperatures drop later Sunday. Single-digit temperatures could last into Monday.

On Friday, New Jersey and Pennsylvania declared states of emergency.

"This storm has the potential to deliver every, every winter weather option that mother nature has," Pennsylvania Gov. Tom Wolfe said at a news conference.

In New Jersey, the state of emergency will go into effect at noon. "Our top priority is the safety of New Jerseyans, and we urge residents to stay off the roads and prepare for potential power outages," said Gov. Phil Murphy.

Officials warned of flight disruptions at airports, as well as possible changes in train schedules. The Chicago Department of Aviation reported more than 300 flights at O'Hare and Midway international airports had been canceled as of Friday evening. Amtrak canceled some trains Saturday from Chicago to Washington and New York and between New York and Boston and Pennsylvania on Sunday.

Chicago is forecast to receive as much as 8 inches by Saturday and wind gusts in the Chicago area are expected to reach 35 mph. </s> • New York and surrounding states were gearing up for a second winter storm within a week on Wednesday.
• Between 6 and 12 inches (15 and 30 cm) of snow are forecast for New York City and the surrounding suburbs in New Jersey and Connecticut through to Thursday morning.
• The storm will spread west into Pennsylvania and up past Boston into New England where some locations may get as much as 2 feet (60 cm) of snow.

NEW YORK (Reuters) - New York and surrounding states were gearing up for a second winter storm within a week on Wednesday, with less wind but more snow predicted this time around as thousands remain without power from the last nor'easter.

Between 6 and 12 inches (15 and 30 cm) of snow are forecast for New York City and the surrounding suburbs in New Jersey and Connecticut through to Thursday morning, with wind gusts creating "near-white out conditions" for commuters, the National Weather Service said on Tuesday.

The storm will spread west into Pennsylvania and up past Boston into New England where some locations may get as much as 2 feet (60 cm) of snow. Snowfall may turn to wintry rain in some areas, depending on how much of the storm stays out at sea.

This week's storm is not forecast to have the hurricane-strength winds whipped up at times by the storm last week, but forecasters say strong gusts of 60 miles per hour (96.56 kmph) and accumulated snow will still be sufficient to knock down more power lines.

Some 250,000 homes and businesses in the region were still without power on Tuesday after the previous nor'easter.

The governors of New Jersey and Pennsylvania declared states of emergency, which gives them access to support from the U.S. government if needed. New Jersey's Department of Health warned of treacherous driving conditions.

NYC Emergency Management said the city had 234,000 tons of rock salt on hand and was deploying 693 salt spreaders. City officials advised residents to avoid roads and stick to mass transit instead.

Amtrak canceled some of its Wednesday trains between Washington and Boston as well as some services in Pennsylvania, New York state and other areas of the Northeastern and Mid-Atlantic United States. </s> The National Weather Service out of Binghamton has issued a " Winter Storm Warning " for Central New York 1AM Tuesday - 1AM Wednesday.

For the cities of Rome, Utica, and the rest of Central New York, we are looking at heavy snow showers:

Total snow accumulations of 7 to 10 inches expected. Snowfall rates up to 1 inch per hour are expected Tuesday into Tuesday evening. Winds gusting as high as 30 mph."

A Winter Storm Warning for snow means severe winter weather conditions will make travel very hazardous or impossible. If you must travel, keep an extra flashlight, food and water in your vehicle in case of an emergency. </s> A "significant winter storm" will strike the Ohio Valley, Appalachians, and Mid-Atlantic Thursday and the Northeast this evening, according to the latest NWS Weather Prediction Center's short-range forecast.

A potent upper-level low will push through the Ohio Valley Thursday, resulting in dangerous wintry conditions there to continue and move northeastward.

Models suggest that parts of the Ohio Valley could receive a few additional inches of snow and some freezing rain.

According to the forecast, a low-pressure surface system will gain strength over the Southeast coast and charge northward along the Eastern Seaboard on Thursday and Friday, resulting in freezing rain across the Southern and Central Appalachians as warm air collides with fridge air at ground level. NWS warns ice accumulations could be over a quarter of an inch there.

Later this evening, into the overnight hour, the upper-level and surface lows are expected to produce "a perfect storm" with heavy snowfall in the northern Mid-Atlantic and into the interior Northeast. Snow totals in interior Pennsylvania and New York could measure about one foot. State and local governments across the Northeast have already issued Winter Storm and Ice Warnings as well as Winter Weather Advisories.

Models show the heaviest of this wintry precipitation will remain slightly west of major cities DC, Baltimore, Philadelphia, and New York City, but a wintry mix is possible for those areas Thursday evening and could cause severe travel headaches.

"A strong early season winter storm is impacting the central and eastern United States to end the week, spreading snow and ice into places like St. Louis, Indianapolis, and other portions of the Midwest early Thursday. Heavy snow and ice is anticipated to impact the suburbs of the I-95 corridor from Washington to Boston, with even some brief wintry precipitation into the major cities before a change to rain. However, strongest impacts will be felt from central Pennsylvania northeastward into the mountains of northern New England where locally up to 0.25” of icing and a foot of snow is expected. This storm is coming as a strong push of cold air coming down from Canada interacts with Gulf of Mexico moisture, resulting in early season wintry precipitation. As the storm departs, more cold air will likely reinforce itself back into key natural gas consuming regions of the Great Lakes and Northeast next week, furthering the bout with sustained above normal heating demand in these regions," reported Ed Vallee, head meteorologist at Vallee Weather Consulting.

Weather models show record low temperatures for some parts of the Northeast.

As the cold weather pours into the Northeast, the US-Lower 48 heating degree day (HDD), GFS Operational, a measurement designed to quantify the demand for energy needed to heat a building, has abruptly moved higher.

And maybe the HDD surge was one of the triggers that blew up a fund's short natgas book.

Yesterday morning, the price of the 1st month natgas contract soared, spiked as much as 20% in minutes - the biggest intraday move higher since 2009 - with the price exploding higher once a barrier of stops at $4.40 was tripped, at which point furious short covering sent nat gas as high as $4.929 in just seconds, the highest since February 2014, when the US experienced its "polar vortex" winter.

Putting the move in its long-term context shows just how breathless the recent short squeeze has been.

What is social media saying about 2018's first winter blast? </s> A winter storm system bringing blizzard-like conditions across the Upper Midwest on Monday will dump wintry weather across parts of the Deep South and Northeast by midweek, creating treacherous travel conditions.

The National Weather Service's Weather Prediction Center said that parts of southeastern Minnesota and Wisconsin could see over a foot of snow. The winter storm will then bring upwards of a foot of snow to Michigan before targeting the Northeast overnight Monday into Tuesday.

Rain and snow will develop along an arctic front associated with the storm over parts of the Ohio Valley stretching into the Lower Mississippi Valley on Monday, according to the NWS. The snow and rain will move eastward by Tuesday afternoon, affecting cities such as Birmingham, Atlanta and Nashville.

WIND CHILLS OF MINUS-45 TO MINUS-60 EXPECTED IN CHICAGO, MUCH OF UPPER MIDWEST

"A dangerous week of cold air and travel conditions are coming up," Fox News Senior Meteorologist Janice Dean said Monday. "Snow and ice will coat even the Deep South Tuesday through Wednesday, which will make travel incredibly difficult and possibly crippling."

Winter storm warnings and advisories were posted stretching from Mississippi stretching up through Tennessee into West Virginia.

Winter storm watches were also posted for the Atlanta area for Tuesday were up to 2 inches of snow may fall, FOX5 reported. Public works crews were spending Monday pretreating roads in Atlanta, which has a busy week ahead of the Super Bowl on Sunday.

Further north, the Minnesota State Patrol was responding to scores of spin-outs and crashes early Monday in the Twin Cities metro area, even before the busiest commute time, because of snow-covered and icy roads.

"Plows are out across the state. Heavy snow overnight and blowing and drifting snow are making for some tough conditions," Minnesota Department of Transportation spokesman Kevin Gutknecht told the Associated Press.

In Wisconsin, plow drivers were having a difficult time keeping up with the snow in Sheboygan. Courthouses and most offices were closed in Milwaukee, Waukesha, Columbia and Washington counties, while dozens of flights were canceled early Monday at Mitchell International Airport in Milwaukee County.

WHAT IS A POLAR VORTEX? A LOOK AT WHAT COULD BE IN THE FORECAST THIS WINTER

Up to 3 inches of snow is expected in the South, while the interior Northeast will see between 6 inches and a foot of snow by Wednesday night.

The storm system is associated with an arctic front that is responsible for a cold air outbreak associated with the polar vortex that will bring bone-chilling cold to the Midwest.

Temperatures on Wednesday could fall to 30 degrees below zero, and could feel as cold as 60 below because of the wind chill.

"Some of the coldest air in decades will pour in across the Northern Plains, Midwest and Great Lakes with windchills in the negative-40 to negative-50 degree range and air temperatures below zero for several days," Dean said. "This will be dangerous and potentially deadly for these regions, and people need to stay inside."

The Associated Press contributed to this report. </s> (Reuters) - A winter storm bringing icy rain to the Great Plains and Midwest claimed the life of a Missouri woman on Friday, prompted the delay of an NFL football game and threatened power outages and treacherous conditions throughout the weekend.

Ice, freezing rain and winter storm warnings were in effect from the Texas panhandle north into Iowa and east through central Indiana, the Weather Service said in an advisory, and both Missouri and Oklahoma had declared states of emergency.

“Significant amounts of ice accumulations will make travel dangerous or impossible,” the weather service said. “Travel is strongly discouraged. Commerce will likely be severely impacted.”

The storm’s first known casualty was Tiffany Jackson, 31, of Crystal City, Missouri, who police said lost control after driving too fast on an icy overpass. Her vehicle slid off the road and struck multiple trees, the Missouri State Highway Patrol said, causing her to die at the scene.

Forecasters warned that ice accumulation from the storm could be more than half an inch (1 cm), creating slick roadways especially on bridges and overpasses, and possibly causing scattered power outages across the region, the service said.

The National Football League postponed the start time of a divisional playoff game between the Kansas City Chiefs and the Pittsburgh Steelers in Kansas City from around noon local time on Sunday to 7:20 pm, when conditions are expected to ease, the Chiefs said on the team’s website.
