The polar vortex, a recurring winter phenomenon, is once again making headlines as it prepares to unleash some of the coldest temperatures of the season across the eastern United States. This extreme weather event, characterized by a large area of low-pressure cold air typically located near the poles, is dipping southward, threatening millions with bone-chilling cold and hazardous conditions.
Key Information Across Sources
Temperature Extremes
Forecasts indicate that temperatures could plunge well below freezing, with some regions experiencing lows up to 45 degrees below average. Wind chills are expected to make the conditions feel even colder, with some areas facing life-threatening values as low as -50°F (-45°C). Cities like Minneapolis are bracing for highs of -3°F (-19°C), while more southern areas may also see unseasonable cold.
Geographical Impact
The arctic air is projected to sweep across the Plains, Great Lakes, and interior Northeast, with its icy grip extending as far south as the Gulf Coast. South Florida may be one of the few areas to escape the extreme cold, offering a rare haven from the frigid temperatures.
Duration
This arctic outbreak is expected to persist through the first few weeks of January, leaving many regions under prolonged freezing conditions. Residents should prepare for an extended period of discomfort and potential disruptions.
