You thought that was the response? I thought that was way too fast for a response to the SSW.
Apparently it was, according to what i read, usually the response takes two- three weeks
It looks as though the response to the late February stratospheric warming is taking place now except in the USA where the eastern seaboard is much colder than normal and a nor'easter will take place in the coming days bringing blizzards. This is a contrast to the warm Winter they recorded. Meanwhile, temperatures at home are expected to go back down to average or stay slightly above for the next 7-10 days after a warm weekend.
