A blast of arctic air, combined with gusty winds, will take aim on the Upper Midwest and Northeast this weekend.
The polar vortex will briefly drop over the Hudson Bay in Canada. From this position, arctic air will have a direct route into the northern tier of the eastern United States.
The main thrust of the cold air will arrive across the upper Great Lakes on Saturday and will settle into New England, New York, Pennsylvania and New Jersey on Sunday.
This
graphic shows the track of an Alberta Clipper storm and the timing of
the leading edge of the arctic air. Temperatures will climb ahead of the
arctic push."Temperatures in the swath of the arctic air will be 10-20 degrees Fahrenheit below normal, which will be the largest negative anomalies since Valentine's Day," AccuWeather Long-Range Meteorologist Joe Lundberg said. "When the wind is factored in, it will feel a whopping 40-60 degrees colder than it will late this week."
This weekend, normal highs are in the lower to middle 50s in Minneapolis, Chicago, Detroit, Cleveland and Boston, the upper 50s in Pittsburgh and New York City and the 60s in Philadelphia.
During the peak of the cold air, daytime temperatures will be no higher than the 20s from northern Minnesota to northern Michigan, northern upstate New York and northern New England. Temperatures at night will dip into the lower teens and single digits over much of this swath.
Winds will gust between 40 and 50 mph over much of the swath as the arctic air approaches and settles in. Gusts topping 50 mph are possible from eastern Pennsylvania and New Jersey to New England.
Airline delays and difficulties for high-profile vehicles are likely. The gusts could be strong enough to cause sporadic power outages.
The combination of wind, cold, dry air and other factors will result in AccuWeather RealFeel® Temperatures 10-20 degrees lower than the actual temperature.

Buds and blossoms that have pushed out on some fruit trees, bushes and vines could be damaged.
The air will become plenty cold enough to trigger bands of lake-effect snow and snow showers. Some of the snow showers can extend all the way to the coastal areas of the Northeast.
In addition, an Alberta Clipper storm will produce a swath of steady snow from parts of northern Minnesota to portions of northern and western Pennsylvania, upstate New York and New England this weekend.
Enough snow could fall to cover the ground and make for slippery spots on area roads.
It is behind this clipper that gates of the arctic will be opened, and it may take until Monday until the lowest temperatures of the outbreak are realized.
"The worst blast of cold air will be the first episode this weekend into Monday," according to AccuWeather Lead Long-Range Meteorologist Paul Pastelok.
One and possibly two additional thrusts of arctic air will follow next week.
A second clipper storm could spread steady snow a bit farther to the south from Monday into Tuesday. Correspondingly, some chilly air could push farther south than from the first blast in the wake of the second clipper.
"The second and third pushes of cold air will pale in comparison to the weekend arctic outbreak," Pastelok said. "The two additional cold waves will not have nearly as much wind with them and the source region of the cold air will trend less extreme as the polar vortex begins to retreat northward."
While temperatures could approach the level of cold experienced with the blast this weekend, RealFeel Temperatures may be significantly higher with the additional cold waves next week.
Beyond next week, the arctic air will be turned off. However, episodes of clouds, rain from the Gulf of Mexico and the Pacific Ocean, and easterly winds from the Atlantic will play roles in holding back temperatures.

Actually this is probably not global warming.

CRAP!! It's screwing up my fishing! lol

winter cold is great but artic air in april just has a special ring to it!
Kevin Stojda ·
A
low of 17F here in N Connecticut on monday morning sounds great, nice
flash frozen spring flowers/blossoms. Hopefully we get a few inches of
snow next week.

The
thing that worries me is the strong wind gusts. We get wind gusts
topping 50 mph and it's a fair bet the power will be knocked out. Even
40 to 50 mph gusts may result in power outages. I hate power outages.
Curtis Grant ·
you just keep that global warming to the east of iowa. And i will be very happy here.
Ed Roberts ·
I for one like ACCU weather info with what they put out our local TV forecasters should look at this
James Anthony Hines ·
Typical
of an ice age pattern that is unfolding here as the magnetic pole shift
occurs and the primer fields weaken across North America. So it seems
to be that catalysmic natural disasters are afoot in North Amerixa which
none will be reported eh until it happens of course.

When will NYC have above normal temps again?? Usually in April is when we get a mini summer preview with 80 degree tmrps

Looking more like April 2007 and 2003 in Southern Ontario.
Tom O'Bedlam
Hmmmm.
Wait, slightly amended version of last week's gloom and doom article
about a polar vortex plunging the Midwest/Northeast into Jan-Feb temps?
Yet people's local forecasts show slilghtly cooler-than-average nights
and seasonable or above days. Naw, nothing sensational here.
Randy J. Anderson
Real below average! Like 2007! Easily 20-to-30 below average!
COLD Weather SUCKS
I
find it highly irnoinc that many on here have posted insults directed
toward accuweather, and remain for all to see, but when I make a comment
it gets deleted....I would like to know why, when I have not insulted
anyone on here.....and for the record...COLD WEATHER SUCKS!!!!!.....

Rick Savard no offense but that is uncalled for.
Michael Carenza Jr. ·
I hope CWS does not go back to his old ways. Because then Rick would be right. He use to insult everyone.
Randy J. Anderson
I don't like this, I see February-like temps coming my way!
James Anthony Hines ·
Huh with the approcah of the vortex just how would it effect the climate in a La Nina pattern?
John Baker ·
im
looking at local forecast for pgh pa on sunday - in the height of the
"polar vortex" - high of 44 degrees and im confused ... today tues at
1230pm its 5 degrees colder than that --- am i currently in a vortex and
dont know it ????
Alex Sosnowski ·
The
story never said "the vortex" was crossing into the U.S., only that it
would direct arctic air southward. Maybe we're wrong, but when the wind
and low-dewpoint air get factored in on Sunday, I don't think people are
going to be comfortable sitting at the game in shorts and t-shirts. My
guess is progs are not catching the intensity of the arctic air in the
lowest levels of the atmosphere. They never do.
John Kedderis ·
Alex Sosnowski you people at Accuweather are never right!
Joey Durso ·
John Kedderis if they never right why you on this webpage?
Alex Sosnowski ·
Says the 2nd clipper (Sunday-Tuesday) could go farther south.
Howard Sprengeler ·
Wasn't
this the same cold air that was supposed to hit Iowa down to the
southeast states, predicted just a couple of days ago? Now it's so much
further north so by the time it gets here, it may not even happen. The
sky isn't falling like they want you to believe.
Jeffrey Banks ·
The models definitely intensify the cold which doesn't seem logical at this time of year the cold air just isn't there.

Just look at the initial.
http://weather.unisys.com/gfs/init/gfs_500p_init.gif
So I know you can't fully believe the models but they give a pretty good picture that there will be cold air but it will be moderated in terms of how cold that air is.

COLD Weather SUCKS
Warm weather sucks even more.
Warm weather sucks even more.
Joseph Graziose
COLD Weather SUCKS
I am currently taking 10,000 IU's of vitamin D a day and my levels
still "suck"....not only am I uncomfortable in the cold I really need to
get off this computer arguing with people who have baseboard heating
about the benefits of cold weather, and get out into that sun ASAP. when
it returns......wish I lived in San Diego instead of Long Island but
would miss my kind of people, and cultural orientations, still if I won
the lottery.......maybe people who have good Vit D accept the cold, but i
can't believe it's universal....
COLD Weather SUCKS
Joseph
Graziose Same problem here, man.....not enough sun, & I am popping
Vitamin D like it's candy...but our cold weather lovers will fire back
with "don't like it?..MOVE!!!"...yet when the shoe is on the other foot,
and a massive heatwave goes as far north as Maine, they get all bent
when being told the same thing.....Oh the hypocrisy!....
Kevin Stojda ·
Joseph Graziose It's called Florida, move there if you need sun. This was a year without winter, so I'll take all I can get.
Debbie Brunell
COLD Weather SUCKS
i know it wll not last but that is ok, it has been SPRING for almost 2
weeks and every day that is cool or cold is a bonus! looking ahead
APRIL also looks to be cool temps, so that just makes it another MONTH
closer to FALL...you also have a nice day...
Kevin Stojda ·
Debbie
Brunell The fall season of winter continued into January. Only late
month and February had any kind of snow or cold weather this year. The
local ski areas really suffered with lots of early layoff's.
