Thus, it leads to our daily weather shape in many different ways, as it works as one large hemispheric circulation in general. And although the Polar Vortex spins well above our heads, it remains close-connected with the lowest parts of the atmosphere we live in. The Polar Vortex is the strongest during the winter months in both the Northern and the Southern hemispheres. and recently also in Europe and Asia as the vortex shifted on the other side of the northern hemisphere. We could experience this quite a lot in Canada, the U.S. It has the main and major effect on the winter weather across the high and mid-latitudes every year. The vortex extends from the middle of Earth’s troposphere up into the stratosphere layer. The Polar Vortex is spinning around the North Pole, grazing through the air at about 20-50 km above the Earth’s surface.īoth the troposphere and the stratosphere are actually pretty crucial for our climate, as the Polar Vortex covers most of the bottom half of the atmosphere. This is the Polar Vortex, an enormous, tri-dimensional ring of very powerful winds moving through the sky high above us. The stratosphere also has the Ozone layer, which has a vital role in the protection of our planet’s life against the potential storm impacts from the Sun or outer space.Īnother thing in the stratosphere, which is making our weather even more variable, often triggers some significant large-scale weather events. It is an 11-50 km thick layer and the air there is also very dry. It gets much thinner above the North and South poles.Ībove this layer, there is a much deeper one, known as the stratosphere. The troposphere is the deepest above the equatorial region. The depth of it varies from around 8 km to almost 20 km, depending on where you live. It is about 12 km deep, extending from the ground up high into the sky. The layer close to the Earth’s surface is the troposphere. Those two are known as the troposphere and the stratosphere layers. The majority of the dynamics for our daily weather occurs in the lowest two layers. The Earth’s atmosphere is built of six layers, rounding our planet. So, before we head into deeper details regarding the potential evolution of the winter storm Quinlan in the coming days, here is a quick overview of what the Polar Vortex is and why is it important to know when we track our daily weather.

It has been very active through the whole winter season, now finally losing its strength. The background behind these significant cold outbreaks across the North American continent is found in the activity of the Polar Vortex aloft. Severe winds, heavy soaking rain with floods, and a couple of tornadoes will be possible on Friday. The cold front advancing into the warm and moist air spread across the Southeast, with Alabama, Georgia, South Carolina, and northern Florida in particular, will also enhance chances for severe thunderstorms. A major snowstorm is likely to develop along the low, with severe winds and potentially blizzard conditions affecting millions across the Northeast. With the interaction of the Arctic cold air with the warm subtropical air mass spread across the Southeast, the system will begin strengthening through Friday night, becoming the next bomb cyclone as it grazes across the East Coast, reaching New England late Saturday as a violent Nor’Easter storm. Bringing near-freezing temperatures and unseasonably cold air also far south along the Gulf Coast of Texas, Louisiana, and Mississippi before the system ejects farther east. A major cold blast with temperatures 40-50 ☏ colder than just recently will follow behind the storm, putting central and northern U.S. Then, the low is forecast to considerably deepen while moving across the Southeast and rapidly intensify as it turns towards the Northeast on Saturday. on Sunday, some areas even colder than Alaska Record Cold with 40 ☏ below normal Temperatures to impact Southeast U.S. The system will emerge over the Rockies on Thursday, blanket the central and southern Plains with fresh snow, from northern Texas and Oklahoma to Ohio, Kentucky, and Tennessee, and also the northern parts of Mississippi and Alabama on Friday. Meanwhile, the Polar Vortex aloft is *finally* weakening its strength and moving away from North America.Ī potentially significant impact of a new winter storm Quinlan is shaping up for a large portion of the country in the next few days, with snow also for the South. Snow is forecast to spread across the South before the system becomes the next Nor’Easter bomb cyclone for the Northeast on Saturday.

A major winter storm Quinlan will blast far south across the CONUS, reaching Gulf Coast, Florida, and East Coast through Friday. After a record-breaking warmth recently, the weather is going to significantly flip across Canada and the United States in the coming days.
