In this video I will discuss a strange wild temperature event that happened on December 20, 2016 in Saskatchewan, Canada. On that day the temperature was 25 degrees Fahrenheit (20 degrees Celsius) on the western border and -36 degrees Fahrenheit (-38 degrees Celsius) on the eastern border. A difference of 60 degrees Fahrenheit (34 degrees Celsius) in 400 miles. This happened because of the northern hemisphere polar jet-stream and subtropical jet-stream.
