The above Video Still from AccuWeather was taken TODAY and shows a Jet Stream Shift coming to the North West USA over the Weekend.
This Jet stream shift looks to be a predictable event using the recent Monthly November USA forecast from Piers Corbyn.
The current "Red Warning" R5 period (8th - 10th November) seems to be altering the loction of the Jet Stream and no doubt this change will also apply in other areas around the world at the same time inc. Europe.
