00:00All right, an ice and snowstorm will shut down travel across the United States beginning Saturday
00:05night, Sunday, and lasting into Monday. In fact, it may not be until the middle part of next week
00:12before everything, at least flying, flights across the country can return to normal. I want to take
00:17you to the ice storm that we are going to see here across the country. It is going to be extensive
00:23and it does include most of Texas here. Let me get this off here, generic. There we go.
00:36There we go. This is going to include a large part of Texas and into the Carolinas here. Now,
00:43there's going to be a little difference here. The northern part of this area, let me change this.
00:49The northern part of this area from Dallas all the way up into the Carolinas, a lot of this is going
00:54to be sleet. Now, there's a little difference with sleet than freezing rain. Freezing rain is far
00:58different and far more damaging than what freezing, than sleet is. Freezing rain is far worse and it
01:09looks a little different. What happens is with sleet, you get a little warm layer in a little nose of the
01:15atmosphere that's mostly below freezing. Freezing rain, a lot of the atmosphere is above freezing and
01:21it's only the ground that's below freezing. And I can show you that. That's what I want to show you
01:27what these different profiles look like. I want to take you to Dallas-Fort Worth. This is Saturday
01:35evening here. We think this is mostly going to be a sleet storm. And here's why. This is the zero line,
01:46as we call it, from the surface. What you're looking at here, this is the temperature, this is the dew
01:52point. The temperature's in red, the dew point's in green. What you're looking at here, this is the
01:57freezing line. And we're looking at the temperature and dew point from the surface
02:03to a loft. So we're going higher up in the atmosphere as we look from bottom to top. And
02:14you'll notice, here's the zero line right here. And you notice this little area right here. It's well
02:21up in the atmosphere, about eight, nine thousand, seven, eight thousand feet. You've got what I call a
02:25warm layer, where here's your zero line, freezing line. And this is all above freezing. But once you
02:33get to about five thousand feet or so down to the surface, you're below freezing, right? So here's your
02:38zero line again, the freezing line. This is above freezing. This is below freezing. So what happens is
02:50you get snow up here. It reaches that, it hits that warm layer, it melts. And then as it goes below
02:59freezing, it goes to ice. That is sleep. Notice the difference though. I want to go to Columbia,
03:05South Carolina. This is freezing rain. And you can see why. Here's your freezing line. Again,
03:13much of the temperature and dew point is above freezing. So snow here goes to rain, but there's
03:21a thin layer right here above the surface where it goes below freezing. And that's where you get
03:28the ice to melt or the ice or the rain freezes to ice on contact. Freezing rain, far worse.
03:37Let's take a look at the storm here. Here's what the question continues to be. How far north does this
03:45freezing, does this mix line go into the atmosphere here? Or how far north does it get? Here we go.
03:53Here's European. This is Sunday morning. The ice, the pink showing you the freezing line goes to about
03:59New York City, Philadelphia, Baltimore, Washington, D.C. But from the Pennsylvania Turnpike on north,
04:04it is all snow. That's the European, the American model, much farther south. But it takes it to the
04:12Pennsylvania, Maryland border. So where you're all snow, there's going to be a big, big dump of snow.
04:19I want to show you some snowfall accumulations. What do I believe? I believe that the ice line,
04:25the mixing line, sleet line is going to come southern parts of Pennsylvania, maybe as far north,
04:30maybe as far north as the Pennsylvania Turnpike. But I don't believe it'll be any farther than that.
04:37It's a big snowstorm. We haven't seen this wide of a snowstorm in quite some time. Take a look at this
04:42as we take a look at the snow accumulations here. Solid area of 6 to 12 inches from Wichita,
04:48Oklahoma City, near St. Louis, Louisville, southern parts of Indiana, downstate Illinois,
04:55in towards cities like St. Louis. I think Pittsburgh, you're going to end up with a foot of snow
04:59very close to it. But as I zoom in, you see another area where we have now highlighted 12 to 18 inches
05:08of snow in this dark blue. And AccuWeather local storm acts of 30, which means there's going to be
05:15locations within this blue area that pick up nearly two feet of snow. And you can see the area,
05:22including Harrisburg, Near State College, Wilkes-Barre, Scranton, southern Hudson Valley,
05:27I think all of southeastern New England, at least a foot of snow. Some spots will get in this dark
05:33blue, and we may extend this south, even toward Providence and Hartford, will get over a foot of
05:40snow, at least a foot of snow in those areas. How about Washington, D.C., Baltimore, Philadelphia,
05:456 to 10 inches with the potential of a foot of snow if the changeover to sleet is delayed.
05:51I think New York City, if it doesn't mix with sleet, we have four to eight. I think you'll get a foot of
05:56snow, along with most of Long Island, will also get a foot of snow if there is no mixture to sleet.
06:03Pittsburgh, I think a solid, we have six to 12 in this area, I think there could be a foot of snow
06:08very easily. Now, take a look at the map. We may change this here and there, but the general theme
06:14of a major snowstorm is on the way, and because of the cold, we're going to be looking at snow ratios.
06:21Usually, an inch of liquid would be a foot of snow. We could be looking at an inch of liquid being
06:27over 15 inches of snow because it's a dry, powdery snow, and I want to remind you of something.
06:32The cold that is with this storm. Take a look at this as we end the feed right now here. Look at
06:39this. This is the cold. Saturday morning, when you get up, the freezing line down the Texas and
06:48all of this area in pinks below zero, and that's the feed.
