The Polar Vortex core moving into North America

"The lower Polar Vortex is much more dynamic and CAN BE BROKEN APART.

Is PRESSED from BOTH the Pacific and the North Atlantic side.

...an active cold air transport line directly from the polar regions."

Depending on where you are this Thanksgiving, freezing your leftovers shouldn’t be a problem.

Be prepared for an Arctic blast in the heartland, with wet weather in the East.

We're in for a very significant blast of Arctic/Siberian air later this week and into early December.

This airmass will drop temps up to 25°F below average in some areas, but most of the CONUS will be at least 10°F below average.

Snow will be possible for parts of the Great https://t.co/QUMBDEiJ4u

@NWS

The first arctic outbreak of the season is set to move through the eastern U.S. this week bringing a chilly holiday weekend for many. Dangerous wind chills across the Upper Midwest and heavy snows downwind of the Great Lakes will accompany this wintry blast. https://t.co/Q9ma6e057O

A lobe of the polar vortex threatens to bring some seriously cold and possibly snowy weather to the United States during the week of January 6th.

Frigid air will overtake just about the entire country.

"Such plunges occur when the air currents that keep frigid air over the North Pole - the polar vortex - weaken, and the freezing arctic air slips south and pushes the vortex down with it. A perfect recipe for wintery weather."

Beyond the winter storm there will be no shortage of cold shots for the eastern USA through mid month... at least. https://t.co/5Q1Djf2PAl

"This pattern is expected to last through at least the middle of January.

But not everyone will be cold. Warmer early-mid January temps are expected in the West as a result of the jet stream buckling north into western Canada."

Strong winds will also accompany the arctic air. Those winds will combine with the cold."

Tampa Bay is about to see our coldest stretch in 2 yrs. The extreme cold advertised earlier by the models will NOT materialize BUT we will still see impressive cold. From Tues to Fri of next week "high" temps will stay in the 50s each day! That's ~15 degrees below normal. @WFLA https://t.co/DgBB634Sin

@RyanWeather

It may have taken an extra few weeks, but radiation out to space in the Winter Arctic has produced extreme cold pools that will now slosh around from Siberia to North America during the next 7-10 days.

The NE Pacific is trying very hard to shut off the cross-polar valve of cold https://t.co/ly8ApSpgpQ

@NOAAClimate

Another surge of very cold air looks to drop down from the Arctic over a large region of the central U.S. this weekend and into early next week. Is THIS cold air outbreak related to the Polar Vortex?

@WeatherProf

The jet stream that helped dump a foot of snow on the Gulf Coast is now accelerating over the Atlantic, helping fuel the strongest storm on record over Ireland with 100 mph gusts and 50 ft waves! It is so strong NOAA sent a hurricane hunter to Ireland to collect data!

@severeweatherEU

Are you ready? The potential for a significant deformation of the Polar Vortex and its split through mid-February is increasing.

Stay tuned for an in-depth analysis and forecast soon. https://t.co/HMgHSKFir4

@Ventuskycom

For the first time this winter, the polar vortex is expected to break up. 🧐 Although it is currently strong, it will begin to weaken over the next seven days and split into several smaller vortices by mid-February. This process could bring below-average temperatures to Europe in https://t.co/CRHRuA6RvT

"It shows the stratospheric high-pressure system to grow very large and push against the Polar Vortex. This completely changes the wind dynamics in the stratosphere. This is almost like sparks flying when the two large systems collide in the stratosphere."

@severeweatherEU

A strong Stratospheric Warming event is now forecast for mid-March, and it will create a full collapse of the Polar Vortex in the stratosphere. It will impact the pressure patterns over North America first, based on the early projections.
