As winter tightens its grip on the nation, there\u2019s no shortage of atmospheric drama to talk about.<\/p>\n

The real headline-grabber this week is the surge of arctic air pouring in from the north. That in turn has set the stage for a winter storm that could grind to a halt parts of the Southern and Central U.S., with ripple effects stretching from Texas to the Gulf Coast, the Carolinas and the Mid-Atlantic.<\/p>\n

At the heart of all this is the polar jet stream, a fast-moving river of air five to seven miles above our heads, which acts like a thermostat and storm track. This week, it’ll drag frigid Canadian air deep into the Plains and South. That dip sets up a classic battleground between cold, dense Arctic air plunging south and moist, warmer air pushing up from the Gulf of Mexico.<\/p>\n

That kind of setup is meteorological rocket fuel for winter storms.<\/p>\n

Impact from Texas to the Carolinas<\/p>\n

By late Thursday into Friday, the storm ramps up in intensity.<\/p>\n

Northern Texas, Oklahoma, Arkansas, and into Missouri and Tennessee: Widespread snow, sleet, and freezing rain could be enough to snarl interstates and threaten power grids in Northern Texas, Oklahoma, Arkansas, Missouri and Tennessee.<\/p>\n

Farther south and east, in Mississippi, Alabama, Georgia, and the Carolinas, a dangerous icing scenario unfolds, where freezing rain will coat surfaces in a thick glaze. This isn\u2019t just a frost-on-your-windshield type of ice. This is power-line-snapping, tree-limb-breaking, travel-halting ice that could lead to days without electricity in some areas.<\/p>\n

\"SevereSevere icing is expected across the southern U.S. (Danielle Noyes\/1DegreeOutside)<\/p>\n

On the southern edge of the storm, where the warm air wins, severe thunderstorms, including strong wind gusts and isolated tornadoes, are not out of the question.<\/p>\n

This storm stretches out from Friday through the weekend on the Eastern Seaboard.<\/p>\n

Could it reach us in Boston?<\/p>\n

Yes, but not with the same ferocity our southern neighbors will endure.<\/p>\n

The main energy of the storm should slide to our south late Sunday into Monday but New England could be grazed by the system’s northern fringe. While the heaviest snow likely stays south of us, a few inches of accumulating snow can\u2019t be ruled out, especially if the storm nudges northward just a bit.<\/p>\n

True arctic air arrives<\/p>\n

After a relatively mild midweek with pockets of light snow Wednesday evening into the overnight, true arctic air arrives Friday night into the weekend.<\/p>\n

Friday Night: Wind chills drop well below zero across the region.<\/p>\n

\"FrigidFrigid air will set into New England by Friday. (Danielle Noyes\/1DegreeOutside)<\/p>\n

Saturday: Highs will struggle to get into the low teens for daytime highs. Coupled with the wind, “feels-like” values will be around or just below zero much of the day with the most intense cold \u2014 10 to 25 below zero \u2014 across northern New England.<\/p>\n

Sunday: Same story. Gusty winds continue. Bitter air holds firm.<\/p>\n

The polar vortex is the primary culprit of this cold snap. Usually, the vortex acts like a “keeper” of cold, locking it over the Arctic. This month, a sudden stratospheric warming event caused the vortex to wobble and stretch. Think of it like a spinning top that\u2019s been bumped, and it\u2019s now “leaking” Arctic air down into North America.<\/p>\n

On top of that, we are currently in a La Ni\u00f1a phase, which typically pushes the jet stream north. But this year\u2019s La Ni\u00f1a is weak and fading toward “neutral” status. That has led to a more unstable weather pattern, allowing cold air to “dip” much further south than usual.<\/p>\n

Is this normal?<\/p>\n

Statistically, this winter has actually seen several record-high temperatures across the country. However, the intensity of the current cold is higher than average for this time of year. We are seeing a tug of war between long-term warming trends and short-term Arctic outbreaks.<\/p>\n
