• Frigid air surges to impact from the northern Plains to the Southeast and Northeast.
US braces for prolonged frigid temperatures
The United States is bracing for a prolonged period of frigid temperatures as the polar vortex extends its reach across North America. Unlike typical disruptions where the vortex weakens and retreats, this elongated pattern is set to deliver sustained cold weather throughout late January. The eastern half of the Lower 48 states is expected to experience particularly harsh conditions, with temperatures significantly below average.
