Western half of US to be hit with temperatures of up to 30 degrees colder than normal after Alaska experiences bone-chilling lows of minus 41F.
Forecasters expect the record-setting cold weather plaguing Alaska to spread to the rest of the United States in the coming week.
Low temperatures have already set in The Last Frontier State, which is witnessing its coldest weather in almost two years.
Record-setting cold weather could strike large parts of the United States in the next week as record-setting low temperatures from Alaska sweep south, climatologists have warned.
The cold blast is set to last between six and eight days.
One weather model expects low temperatures of 25F degrees below the norm in Denver, Colorado, and Rapid City, North Dakota, by December 7, according to Pivotal Weather.
'Cannot recall last time I have seen such a cold anomaly forecast across almost entire USA,' climatologist Roger Pielke Sr. said on Twitter.
