The circulation around the powerful storm that produced blizzard conditions over the northern Plains is sending the chilliest air of the season so far through much of the central United States.
High and low temperatures through the weekend will be more typical of early November rather than the middle of October across the North Central states.
People in Denver basked in sunshine and temperatures in the lower 80s F during Wednesday afternoon but awoke to temperatures in the upper teens on Thursday morning. The temperature plummeted more than 60 degrees in less than 24 hours, making this the largest two-day temperature swing ever recorded in October. AccuWeather RealFeel® Temperatures were near zero Thursday morning while snow created slushy roads.
The city shattered its record low for Oct. 11 of 22 set back in 1946 as the mercury plunged to 9 on Friday morning.

"Temperatures are forecast to rebound quickly over the Rockies and southern Plains into this weekend," AccuWeather Senior Meteorologist Brett Anderson said.
However, it will still be on the cool side for residents of central and southern Texas, with Saturday's highs being held in the 60s in places such as San Antonio and Houston where average highs are still in the 80s at this point in the year.
Temperatures will quickly rebound in these areas Sunday into Monday.
"Chilly air is likely to hang around the northern Plains and Great Lakes region through the weekend," Anderson said.
On Saturday, cold air will continue to circulate around the storm over much of the North Central states.
While the chilly air is forecast to lose some of its punch traversing the Great Lakes and the Ohio and Tennessee valleys, the change will still be noticeable.
When compared to a high of 86 on Friday, temperatures will be slashed by 20 degrees on Saturday around Nashville.
The extensive deep snowcover will play a role in the delayed warmup over the northern Plains.
