Extreme Temperatures
This next push of arctic air is expected to bring air that is just as cold, or even colder than the air that brought subzero lows to the Midwest and Northeast during the weekend.
Millions will shiver from Chicago to New York City as record lows are challenged during this bitter blast. Records may also fall across parts of the South where temperatures manage to fall into the teens and single digits.
Some southern cities forecast to dip into the teens or lower include Birmingham, Alabama; Charlotte, North Carolina; Columbia, South Carolina; Nashville and Atlanta.
Floridians will even experience a taste of the arctic chill with temperatures dipping down to the lower 30s in cities such as Orlando, Melbourne and Daytona Beach.
The worst of the cold is expected to focus over the East for Thursday into Friday.
In the mid-Atlantic, some daily record lows set during the late-1800s will be challenged.
AccuWeather.com RealFeel® temperatures below 0 F will be common across the regions during the daytime hours, including cities along the Interstate 95 corridor. These values can then drop by as much as 20 degrees during the overnight hours, making for a bitterly cold morning commute.
Snow showers are also likely to develop downwind of the Great Lakes late in the week even though the lakes are quickly becoming covered in ice.
Temperatures can be very dangerous, and possibly even life threatening during this arctic outbreak.

Great Lakes ice cover continues to grow rapidly, now surpassing the amount of ice at this time last year.
The total ice cover on the Great Lakes is now rated at 82.3 percent as of Tuesday. On the same date last year, the Great Lakes had 81.6 percent total ice cover.
The Great Lakes ice cover has grown over 5 percent in the past 24 hours. That's about 4,750 square miles of ice overnight. At that pace of ice growth, the Great Lakes would be almost totally iced over in the next four days.
The blast of arctic cold tonight through Friday will certainly help ice continue to grow.
The cold will come with a 10 mph to 20 mph wind, which could temporarily break up and reduce some ice. But the light wind days in the next 10 days also look very cold.
So it's going to be very interesting to watch the ice expand in the next few weeks.
From the bitter cold weather I'm expecting to head our way, combined with several days of light winds, I think we will surpass last year's total ice cover on the Great Lakes. In fact, I'm wondering if we could see the Great Lakes almost totally ice up by the end of February.
Among those beautiful sights is Niagara Falls, which has now frozen over due to temperatures which dropped to 16F on Wednesday.
And it looks like the popular tourist destination may stay frozen, as temperatures are expected to drop even lower come Thursday.
Moisture being pulled to the north from the Mediterranean Sea will combine with cold air from Russia to produce a widespread and long-lived snowstorm.
While western Turkey was hit hard by the previous storm, the worst of this snowstorm is expected to occur across central and east-central Turkey.
The higher terrain of northwestern Turkey can still get a significant snowfall, while Istanbul experiences rounds of snow squalls.
Additional accumulating snowfall is expected in Istanbul Tuesday night through Thursday. Rain will mix with the snow at times, especially during the afternoon hours and when light precipitation falls, but snow will be the primary problem.
Snow totals will vary greatly across the Istanbul area; however, the hardest hit areas could get total snowfall of 15-25 cm (6-10 inches) through Thursday. The period of heaviest snowfall is expected on Wednesday when low visibility and snow-covered roadways are expected.
Snow began on Monday across many areas in central and eastern Turkey, but the heaviest snow will fall into Wednesday in areas such as Erzincan and Erzurum. Occasional snow may even continue to fall into Thursday in some places.
Snow accumulations of 13-25 cm (5-10 inches) are expected to be widespread in central Turkey with local amounts in excess of 30 cm (12 inches). In the highest terrain, total accumulations could near 60 cm (24 inches), which is great news for the many ski resorts scattered across the region, but bad news for travelers.

It worked. You win, East Coast. We concede.
Kevin McGrath, a resident of Dieppe, probably wasn't expecting his home video showing off the amount of snow congregating around his house to hit almost 84,000 views on YouTube in two days but that's precisely what happened.
"Driving conditions will be very difficult and we continue to urge everyone to stay off the roads for the entire day," Baker said in a morning news conference.
Boston measured 16.2 inches of snow in the storm, making this winter the city's third-snowiest on record. Blizzard conditions were verified in Chatham, Plymouth, Hyannis, Martha's Vineyard and Falmouth, where visibility was one-quarter of a mile or less with 35 mph-plus winds for three hours or more.
"There's a little bit of déjà vu all over again," Baker said.
The snow was expected to stop by midday, but the central and eastern parts of the state are under a blizzard warning through Monday morning because high winds will blow snow and reduce visibility.
With the storm falling on a weekend and students set to start February vacation on Monday, no travel ban was issued.
"The most important thing people need to do today is stay safe and take care of themselves," Baker said. "Someone who gets trapped out there. . . it's just going to be a very bad day to be on the roads."
MBTA service was suspended for the entire day on Sunday, and a decision will be made in the afternoon on Monday' service. Flights are not expected to leave or arrive at Logan Airport before mid-afternoon.
Transportation Secretary Stephanie Pollack said more than 3,000 pieces of equipment are treating the roads.
"We're going to need time," she said. "Just because it stops snowing in your area does not mean you should clear your car out and get out there right away."
This next push of arctic air is expected to bring air that is just as cold, or even colder than the air that brought subzero lows to the Midwest and Northeast during the weekend.
Millions will shiver from Chicago to New York City as record lows are challenged during this bitter blast. Records may also fall across parts of the Southeast where temperatures manage to fall into the teens and single digits.

It is possible for some snow showers or flurries to accompany the arrival of the harsh cold, especially across the Tennessee and Ohio valleys. This could drop a few inches of snow, leading to some slick travels.
Snow showers are also likely to develop downwind of the Great Lakes late in the week even though the lakes are quickly becoming covered in ice.
Just take the Weather Channel's Jim Cantore as an example. The 51-year-old meteorologist displayed the infectious enthusiasm of a child while reporting on Sunday's blizzard in Massachusetts, US.
In the video below, which has gone viral over the past 24 hours, Cantore can be seen tramping around in knee-deep snow when the screen suddenly flashes pure white in a rare example of 'Thundersnow' - when lightning occurs during snowfall.
"Oh yes! Yes! Yes!" he exclaims. "We got it baby! We got it! We got it! Woo! Woo! We got it! Yes! Listen to that! Listen to that! Oh baby!"
Just as Cantore begins to regain his composure, the screen again flashes white, setting the excitable weatherman off on another bout of wild celebration. "Oh again! Again!" he shouts, throwing a handful of snow into the air. "That's a two-fer. That's a two-fer, baby. Oh my goodness!"
Four further flashes illicit similar exultations, as the meteorologist gives up any pretence of hiding his excitement.

"It'll be zero degrees and blowing snow, and that's not a good time for everybody," said Roger Sample, who owns a construction business in the town on the shores of New Hampshire's Lake Winnipesaukee and serves as the carnival's chairman.
The carnival, which Sample said has been held for more than two decades, typically draws about 1,000 visitors out onto the frozen lake's Alton Bay for games and rides, as well as to see small planes that land on the ice.
Comment: The northeast USA cannot seem to get a break from the record setting cold and snow, which shows no promise of ending soon:
- Valentine's weekend blizzard to rage in Northeast; bitter cold, powerful winds, whiteout conditions possible
- Frigid air to bring harshest winter conditions to Midwest, East through mid-February
A rescue vessel is rushing to free a damaged Australian fishing ship with 27 people aboard which has become trapped in thick Antarctic ice.
The 207-foot ship, the Antarctic Chieftain, suffered propeller damage after hitting a chunk of ice on February 7 in an isolated region near the Ross Sea, south-east of New Zealand. The ship, which is used for harvesting Patagonian toothfish, became stranded in ice floes up to 10 feet thick and lacked the power to break free.
Les Scott, managing director of Tasmanian-based Australian Longline, which owns the ship, said an underwater video inspection showed three of the four propeller blade tips were damaged. None of the crew has been injured.
