Story summary

A polar vortex is unleashing a brutal chill across the U.S., plunging temperatures below zero and sending wind chills plummeting to a bone-numbing -40°F. Over 300 million people are bracing for this icy onslaught, with weather warnings ringing out from the Midwest to the Deep South, underscoring the stark extremes of winter's grip.

History

Historical Context

The current polar vortex is reminiscent of past extreme cold events, notably the 1985 cold wave that gripped much of North America. That event resulted from a similar southward shift of the polar vortex, causing record low temperatures and significant infrastructure damage. Such patterns highlight the ongoing vulnerability of the U.S. to severe winter weather, exacerbated by climate change and shifting jet streams.
