And also very complex! I publish a 9 day forecast for Rutland at

another similar feature may follow southwest, and still there is
further development in the positive vorticity side of the jet at T=120
over the Norwegian Sea.. After that even the broader scale has badly
wobbled over the last two days, blow trying to forecast out to T=240 -
I reckon best wait till we have a little more ensemble/model cohesion.
