That is we get underway this February 4th.

I'm Carla Zeus.

There's this thing called the polar vortex we've told you about before.

According to meteorologists, it's not accurate to say the polar vortex is coming to get you, but it can cause Frigidaire to invade the continent.

And that's exactly what it will be doing this weekend.

Scientists describe the polar vortex is a low pressure air mass that's located near the Earth's north and south poles.

It keeps the Arctic air bottled up in these areas, but in the winter months, the polar vortex can become unstable and allows some of that frigid air to spill south.

And a single blast of this Arctic air is the main reason why every state in America all 50 including Hawaii, will see below freezing temperatures.

On Monday morning, 86% of the country 235 million people will be affected.

Forecasters predict high temperatures in the Midwest to be 15 to 20 degrees below normal.

Some parts of Wisconsin could see temperatures of 25 degrees below 0 F.

That's one of 16 states expected to see sub zero temperatures on Monday.

Meteorologists don't know how far south the cold air will reach, but some forecasts show cities like Atlanta, Georgia seeing their lowest temperatures in years.

The dangers of all of this especially up North frostbite within 30 minutes if people are outside and not wearing the right kind of clothing freezes and ice jams on rivers or possible snow that comes before the cold could ice up on roads, causing traffic problems.

Forecasters say unusually cold conditions are expected to remain in place for the next 10 days.

12th Trivia.

Which of these US School District's has the largest student enrollment?

Miami Dade County, Florida.

Clark County, Nevada.

Broward County, Florida or Houston, Texas?

According to the U.

S Census Bureau, Miami Dade County has the largest student enrolment on this list.

Oh, at some point last year, schools in all 50 states were closed to in person learning because of concerns about the coronavirus pandemic.

Now, according to Ed week dot or GPI, partial closures have been ordered in five states.

In person, learning has been required in four states and the 41 other states allow in person learning, though many governments have District's decide whether they will be open and what their restrictions are.

Studies have shown that in communities where the virus isn't widespread or where masks air worn and regular testing is done, schools can be opened without causing more problems.

But some researchers air concerned that where there is widespread transmission, there could be mawr exposure in schools, and the kids and teachers who catch Covad there could spread it through their communities.

There have been concerns raised by teachers about their risk of catching coronavirus.

There's a debate raging about whether virtual learning is as effective as in person learning, and experts have voiced concerns that school closures may be taking a toll on students mental health.

So there's no nationwide consensus on what the right approaches, and that's a challenge being faced by other countries as well.

The holidays are long over, but many classrooms across Europe are still empty.

In the UK, schools have been closed to the vast majority of students since the beginning of the year.

A surging coronavirus cases on new Mawr transmissible variants have forced the government to backtrack on earlier promises to get Children back into school for in person learning.

I must inform the house that for the reasons I have outlined, it will not be possible to reopen schools immediately after the February half term.

But some education leaders say the government has been too slow in taking action.

We were saying to government that really, they should be looking at allowing schools to go toe online teaching in the last few weeks before Christmas.

I think if they've done that, we wouldn't have had quite the level of the peak that we've had in this country.

It's a similar story for many of Britain's neighbors.

Schools in Portugal remained open even during the country's strict national lock down in early January.

But a devastating increase in both cases and deaths has since pushed the government to enforce tougher rules ordering schools and universities to close for at least two weeks.

With few exceptions, the thing the government says it's a necessary measure to stem the spread of the variant first found in the UK, But some parents feel it's too little, too late.

This'll is a measure that should have been taken a long time ago, especially before Christmas, when there were fewer positive cases, it would have had fewer consequences for our Children's learning.

Lack of consensus on whether school closures air necessary is evident across the continent.

Along with the UK and Portugal, Germany and Ireland have opted to keep school doors closed to students.

Under most circumstances, Italy and Sweden are taking a regional approach, allowing some in person teaching in combination with online classes, depending on local infection rates.

While the Netherlands will allow kindergarten and elementary school students to return next week aunt In France, Spain and Switzerland, schools are open but with precautionary measures in place, such as mask wearing, social distancing and staggered attendance.

One expert at a leading medical journal told CNN that whilst there may not be consensus on the best approach, decisions on where the schools should remain open need to be considered on a local level.

Different countries have to make decisions based on their situation.

Not all countries have the same level of infection on.

I think schools school closures should be considered within the local prevalence.

While some evidence suggests that schools may not be drivers of transmission, scientists in the UK say that remote learning can help restrict the spread of the virus.

E think schools do have a role to play in restricting they spread of the virus so closing schools can tribute can contribute to a reduction in the transmission of the virus, but not in silo.

Closing schools alone is not going to be enough.

But with new variants on the rise in Europe and beyond, the issue of how soon governments are able to lift restrictions on schools remains a divisive topic from where the Children need to wear masks to whether educators should be made to teach face to face.

For now, there's little consensus on little clarity.

Over the years, we've covered some of the more unusual winter sports, like Snow Chi Ting in Norway, participants can experience speeds of 70 MPH and jumps as long as 500 ft.

There's also ski during or steering in Switzerland, which combines the dangers of both skiing and horse racing.

CNN 10 contributor Chris James reports on um, or traditional winter sport.

Hey, Carl, I'm coming to you right now from Brooklyn, New York, which has been transformed into a winter wonderland, according to the National Weather Service, over 15 inches of snowfall was recorded here, making it one of the heaviest snowfalls in New York City history.

And for today's virtual field trip, I'm taking you somewhere even Snow Air at a much higher altitude.

Ah, place that has become known as the most magical winter destination in the world.

Welcome to the Band National Park in Alberta, Canada.

This little city is literally sandwiched in between the Rocky Mountains.

The summit of Sulfur Mountain is known to be one of the most incredible spots.

Toe watch the sunrise, the most popular winter activity.

No surprise here is skiing and snowboarding the terrain, and Bam is known for being rugged and quite challenging.

The black diamond trails here are not for novices.

Banff is known for having some pretty steep hills, so you better know what you're doing before testing your luck.

This is one of the most popular areas to visit Mount Norquay, which is a short ride from downtown band.

This ski resort dates back to 1926.

It's loved by locals and families alike due to the powdery snow and these breathtaking views.

This is the Lake Louise Ski Resort, which is also located in Banff National Park.

It boasts over 4200 acres, and according to its owners, not much has changed here in this cozy lodge since the 19 seventies.

This is where people can relax with a bite to eat and a warm drink after skiing down those ice cold slopes.

Yeah, speaking of cold, right now, it's 30 degrees outside.

And although Brooklyn is by no means band, I have to say there is something about snow that instantly makes me happy no matter where in the world I am.

Back to you, Carl.

Just like some folks turned to groundhog to predict the weather.

Others turned to animals to predict the Super Bowl and ahead of next Sunday's face off between Kansas City and Tampa Bay.

Ah, Wolverine and Montana picked Tampa Bay.

Or at least he ate the cake with the Buccaneers logo.

But in Kansas City, the goats the animals are wearing chiefs jerseys because when they're not eating hair there cheering on the defending Super Bowl champs, the question is, who's quarterback will be the goat?

That's some people's chief concern.

Brady fans might be thinking the buck stops here.

They're hoping his team will Tampa down the competition.

But even though they're not playing Atma home, it may not matter to the Chiefs if they're not in Kansas City anymore.

Neither Q.

B wants to pass on the chance to go running back to another Super Bowl victory.

Sheridan, Wyoming gets today's shoutout on CNN.

10.

We're rooting for the Bronx of Sheridan High School.

Thank you so much for watching I'm Coral Jesus.
