104 years ago today a remarkable Chinook wind event in North Dakota caused a staggering 83 degrees of temperature change in less than 12 hours near the city of Minot.
The Chinook Wind is a force of nature occurring east of the Rocky Mountains. They form when air moves rapidly down the eastern slopes of a mountain range, being compressed in the process. When the air is compressed, it heats up, and in the case of high Chinook winds, to a great extent!
According to the National Weather Service, on the morning of February 21, 1918the morning low was -33 degrees, but as strong and warm winds blew down the Rockies and eastwards towards North Dakota, the temperature spiked to a high of 50 degrees!
