OK, this is just one distant chart from a suite of some 20 ensemble members from the GFS model, but it’s something pretty special none the less. Complete reversal of the mid latitude zonal winds, Easterly from one side of the chart to the other screaming across the UK.

If such a scenario were to happen it wouldn’t so much be weather, more a complete breakdown of the fundamental laws of physics! Did the Earth’s direction of rotation change?
