Parts of the United States are experiencing frigid weather as a result of the polar vortex. NASA satellites captured the moments as the polar vortex was moving from Canada to the Midwest United States.

Frigid Weather
The U.S. Midwest has been experiencing unusually frigid weather these past weeks، and it’s because of the polar vortex. In many areas، temperatures have dropped to below 0 degrees Fahrenheit، and the weather has caused service disruptions، power outages، school cancellations، air travel disruptions، and even several deaths.

Using NASA’s Atmospheric Infrared Sounder (AIRS) on the Aqua satellite، the agency captured the polar vortex as it was moving from Canada to the Midwestern United States from Jan. 20 to 29. The purple and blue show the coldest temperatures from -40 degrees Fahrenheit to -10 degrees Fahrenheit، and the image shows how the coldest areas are moving southward into the United States.

So far، the U.S، Midwest has been experiencing the lowest temperatures in years.
