WHAT’S HAPPENING?
A front of cold air is moving down from the Arctic, sending temperatures plunging.
......
Temperatures may drop by more than 20 degrees Fahrenheit (11 degrees Celsius) in just a few hours, the National Weather Service predicts.
Wind chill temperatures could drop to dangerous lows far below zero — enough to cause frostbite within minutes. In parts of the Plains, the wind chill could dip as low as minus 70 degrees Fahrenheit (minus 57 Celsius).
......
WHO WILL BE AFFECTED?
Pretty much everyone east of the Rockies — around two-thirds of the country — will see extreme weather
......
HOW LONG WILL IT LAST?
......
The cold isn’t going to stick around for long. After the dramatic plunge that will keep temperatures low for about a week, “everything will snap back to normal,”
......
WHY IS THIS HAPPENING?
It all started farther north, as frigid air collected over the snow-covered ground in the Arctic, Maue said.
Then the jet stream — wobbling air currents in the middle and upper parts of the atmosphere — began pushing this cold pool down into the U.S.
As this arctic air is pushed into the warmer, moister air ahead of it, the system can quickly develop into serious weather — including what’s known as a “bomb cyclone,” a fast-developing storm in which atmospheric pressure falls very quickly over 24 hours.
These severe weather events usually form over bodies of water, which have lots of warmth and moisture to feed the storm, Maue said. But with the huge amount of cold air coming through, we could see a rare bomb cyclone forming over land.
IS THIS NORMAL?
The storm is definitely a strong one, but “not unheard of for the winter seasons,” Oravec said.
It’s pretty normal to have cold air build up in the winter. This week, though, shifts in the jet stream have pushed the air more to the southeast than usual, Oravec said — sweeping the freeze across the country and making storm conditions more intense.
The U.S. probably won’t reach record-breaking lows, like those seen in the cold snap of 1983 or the polar vortex of 2014, Maue said.
Still, “for most people alive, this will be a memorable, top-10 extreme cold event,” Maue said.
