Winter heat wave caused by ‘stuck’ jet stream

The video discusses a sudden shift in weather patterns in the US, with freezing temperatures moving from Alaska and Canada to the lower 48 states. Prior to this, the US experienced record-breaking heat, while the Pacific Northwest and British Columbia faced heavy rainfall. The unusual weather was attributed to a stuck polar vortex, which typically changes shape and position but remained stationary, causing warm weather in November and early December.
