On Monday, Colorado's capital saw a temperature of around 91 degrees Fahrenheit (33 Celsius), which dropped to 36 degrees F on Tuesday morning.

"Drastic change to WINTER starts tonight!," the National Weather Service in Boulder tweeted on Monday.
"Prepare now, for this sharp change from summer to winter!"

After the weather department's tweet, winter indeed arrived in the state on Tuesday with snowfall coming in Denver on Tuesday morning.

Weather forecasters described this phenomenon as one of the most abrupt ever seen in the state in such a short period of time. The change is due to a blast of cold air coming in from Canada.

A few days ago Denver recorded a temperature of 99 degrees F, suggesting the sharp and dramatic fall on Tuesday.

Forecasters say that the bizarre weather is expected to last through Wednesday night and predicted temperature hitting 77 degrees F on Sunday.
