I'm Carla Zeus.

We hope you had a great weekend or that you have a great one coming up.

Let's get started.

There's a new rule in the United States for people traveling aboard planes, trains and some automobiles.

The Centers for Disease Control will require masks to be worn on public transportation and not just in the vehicles themselves.

The order applies to airports, train and subway stations, ferry terminals and ports, places where people wait to use public transportation.

500 says the masks can be cloth, disposable or even home made, and passengers can Onley take them off for short periods of time to eat, drink or take medicine.

Many companies, like airlines, already had mask requirements in place, but up until now it hasn't been the law.

The new 500 requirement effectively makes it one, and that means that people could face criminal charges if they refused to wear a mask.

This doesn't apply to kids under two years old or people who have disabilities and can't wear a mask, medical officials say.

The United States has recorded the most positive coronavirus tests in the world.

More than 26 million of the 103 million reported globally and 100 official says requiring masks on transportation systems will protect Americans and provide confidence in being able to travel safely.

Last year it this time the agency did not recommend that the public wear masks, and a medical professor told CNN this was because there was Onley quote thin and questionable scientific evidence that wearing masks had any benefit.

The hundreds new requirement takes effect Monday night, and it would apply to the Hyperloop concept we've told you about in the past, if that ever gets off the ground, it's not known yet if Hyperloop could be practical or affordable, but proponents of it have a lot of enthusiasm for the magnetic train with a lot of speed.

E love to say that you'll be ableto travel at 500 miles an hour without spilling a drop.

Look, we're using a proprietary magnetic levitation system.

You're literally floating on a bed of air and it will be super smooth.

Were able to achieve these speeds, uh, in a way that we've never seen before.

One of the advantages of what we're doing is that we control the environment.

The tube is completely serene in the way that it is.

So if we think about air travel and turbulence, we don't have any of that.

That is taking place here right now.

E mhm 12th Trivia.

Felix Bernard and Richard B.

Smith teamed up in the 19 thirties to write What Hit song, White Christmas With a song in My Heart, White Cliffs of Dover or Winter Wonderland.

Bernard wrote the tune, and Smith wrote the lyrics to Winter Wonderland.

That seasonal classic describes the upside of winter weather, but a lot of Americans we're seeing it to the extreme.

A cold front swept into the West Coast last week.

It brought powerful winds and heavy rains into central and northern California.

Here's a look at what that rain did to part of Highway one, the Pacific Coast highway.

As the system made its way east.

It put more snow in the forecast for Iowa, Wisconsin and Illinois.

And as it swept over Pennsylvania, meteorologists said it would intensify the result of that A nor Easter, bringing possible blizzard conditions to New York on Monday.

Wind gusts nearing 50 MPH, more than a foot of snow in that region and half a foot or more possible in Washington, D.

C residents were warned of ice and sleep from Maryland down to North Carolina.

In all, more than 110 million Americans, or one third of the country's population, were set to feel the chill of winter early this week to explain some of the different types of that weather.

Here's CNN 10.

Contributor Tyler Mauldin's call A small change in temperature could make a big difference in the type of weather you see from late fall early spring, the period when the U.

S.

Gets impacted by winter storms.

These systems can bring a variety of impacts rain, freezing rain, sleet and snow.

The temperature that determines whether you receive liquid or frozen precipitation is, of course, 32 F, a k a.

The freezing point.

But here's the kicker.

It's not all about the temperature we can feel here on the ground.

Just as important is what's happening thousands of feet in the air between the ground and the clouds, when particles of ice fall from a cloud and immediately encounter warm above freezing air.

All the way to the surface.

It will melt, and you'll need the umbrella, because all you'll get is plain all rain.

On the flip side, if those same ice particles were surrounded by cold below freezing here all the way down, it stays frozen and you'll need a shovel because you're gonna see all snow.

Things get interesting when these particles fall through a mixture of above and below freezing temperatures.

When there's a deep melting layer, followed by a little sliver of sub freezing air at the surface, you'll get freezing rain.

The warm air completely melts the ice in the rain and then doesn't have time to refreeze back into snow.

The rain becomes what we call super cool and immediately freezes to the ground upon contact.

Sleet is similar, except it falls through a smaller layer of warm air and has time to re freeze just a bit before reaching the ground.

And that Carl is the science behind wintry precipitation.

Staten Island, Chuck Chattanooga, Chuck, Woody, the Woodchuck.

How much would Woody Chuck?

These are the names of some lesser known groundhog's animals that once played a part in ancient weather forecasting and modern forecasting.

At least for entertainment value.

General Beauregard Lee and the famous punctuate Tony Phil.

Also factor into this report by CNN's Alison Chinchar.

I'm CNN meteorologist Allison Chinchar on Tuesday.

Punks Itani fill the most famous groundhog in all the land is expected to make his prediction of what the weather is going to be like.

For the next several weeks, the question comes down to Will he see his shadow or not?

Usually, for the last many years, Phil overwhelmingly has seen his shadow, meaning Mawr Winter will be expected.

Since 18 87 he's seen his shadow 104 times.

He has only not seen his shadow about 20 times.

Now, I will say, in terms of accuracy, he has only been right about 50% of the time in just the last 10 years.

However, year over year, his odds have been increasing and improving in the last few.

The forecast for Tuesday in punks Itani, Pennsylvania, calls for snow.

Ah, lot of it.

There will already likely be at least 4 to 6 inches of snow on the ground from this previous snowstorm that will be moving through the couple of days before, but additional snowfall may be coming down when he's making his prediction, which means it might be a little difficult to see his shadow temperatures also very cold, likely in the mid twenties with a wind chill Onley in the low to mid teens.

If that works out, most likely, Phil will not see his shadow predicting an early spring.

The question becomes.

Does Mother Nature agree with that prediction?

Looking at Noah's long term forecast from March through May, it does look like the vast majority of the country is looking at much warmer than normal temperatures.

So in theory, yes, spring is more likely to come early.

In terms of temperatures, we can expect whether than normal conditions across portions of the Great Lakes and drier than normal conditions across portions of the Southwest.

But if you don't like Phil's prediction, whatever it may be, the good news is there is a lot more ground hogs who also make predictions, and chances are at least one of them will give you the prediction that will make you happy.

Groundhog's Air, also known as whistle pigs, and I bet they'd really am up.

The forecast they'd be baking it up is they went along.

Now some might call that a pork choice.

Their friends might rib them about it or bust their chops.

But don't chuck the idea altogether, because turning Groundhog Day in the whistle Pig Day would leave some pickled pink up.

Why did we mention that?

Because they subscribed and left a comment on our YouTube channel.

Have a great day, y'all.
