The polar vortex is a fascinating and powerful weather phenomenon that can bring bone-chilling cold to parts of the Northern Hemisphere
1
. Imagine a massive, swirling mass of cold air and low pressure that usually resides over the North and South Poles
2
. During the winter months, when the jet stream weakens, this cold air can plunge southward, bringing frigid temperatures to lower latitudes, including the United States

.
This winter, the polar vortex is making headlines as it dips down from Siberia, bringing an arctic blast that’s set to freeze much of the U.S
2
. Beginning this weekend, temperatures are expected to plummet into the single digits and even below zero across the northern tier of the country
2
. Wind chills will be even more brutal, dropping into the negative teens and 20s in some areas
2
.
The impact of this cold snap is widespread
3
. Cities from the Midwest to the Deep South are bracing for record-low temperatures
2
. For example, Atlanta is expected to see temperatures drop to the freezing point, with wind chills in the 20s
2
. In the Rockies, Plains, and Midwest, some areas won’t make it out of the single digits

The polar vortex isn’t just a winter curiosity; it has significant implications for daily life
3
. Schools may close, flights could be canceled, and residents will need to take extra precautions to stay warm and safe
3
. The extreme cold can also cause infrastructure issues, such as frozen pipes and power outages

.
Interestingly, climate change plays a role in the behavior of the polar vortex
1
. While the Arctic is warming faster than the rest of the world, this can disrupt the polar vortex, causing it to weaken and send cold air southward more frequently
1
. This means we might see more of these arctic blasts in the coming years.
