Sudden stratospheric warming event expected to develop in next two weeks and will probably weaken the jet stream
A sudden stratospheric warming event is expected to develop over the next two weeks, leading to a rapid collapse of the polar vortex.
This will be the second and probably final disruption of the polar vortex this winter in the northern hemisphere, the first having taken place earlier last month, which was associated with a severe cold spell across much of the eastern half of the US.
